Strive to promote the study of "Juexue"

On May 17th, 2016, in his important speech at the symposium on philosophy and social science, General Secretary of the Supreme Leader specifically pointed out the issue of "Juexue", demanding that the traditional cultural resources be systematically sorted out, so that the cultural relics collected in the Forbidden Palace, the heritage displayed on the vast land and the characters written in ancient books can come alive. These discussions have pointed out the direction for doing a good job in Oracle character recognition, and encouraged the vast number of philosophical and social science workers.

In October 2016, a major project entrusted by the National Social Science Foundation, "Research on Oracle Characters Supported by Big Data and Cloud Platform", was officially implemented. This work has a great responsibility and a glorious mission. Over the past year, researchers in various sub-topics have devoted themselves to it regardless of gains and losses. At present, all the work has progressed smoothly and achieved many phased results.

As we all know, Oracle Bone Inscriptions is the earliest known writing system in China, the starting point and basis for tracing the origin and early development of Chinese civilization, and it is of great value in cultural inheritance, precious and important. However, in recent years, Oracle character recognition has encountered a great bottleneck, and even stagnated. It is scientific and feasible to interpret Oracle Bone Inscriptions by combining modern scientific and technological means with traditional methods, which is worthy of our active exploration and attempt.

The advantages of modern science and technology in assisting the study of Oracle Bone Inscriptions discipline are obvious: the burden of scientific research workers in consulting materials will be reduced, the research efficiency will be improved, and it is possible to chisel HarmonyOS in the recognition of Oracle characters, thus solving many unresolved problems in the study of Oracle bone inscriptions, Yin Shang history and ancient Chinese civilization.

According to the promotion plan of Oracle Bone Inscriptions’s interpretation and reading work, the project has set up 10 sub-topics, and modern scientific and technological means have played an obvious role. For example, the computer film processing technology can implement the image data of the number of Oracle Bone Inscriptions films scattered around the country and the current hiding place; Oracle Bone Inscriptions’s hermeneutic database and glyph digital database are being established, which will help to study the structure and changing law of Oracle Bone Inscriptions’s glyphs that have been interpreted, as well as the relationship with later characters. The close relationship between the meaning and context of characters and the re-checking of controversial Oracle inscriptions are also being carried out one after another.

It can be said that this kind of organized academic research is rare in the history of academic research in China. China Academy of Social Sciences, Tsinghua University, Fudan University, Capital Normal University, China Literature Museum, Henan University, anyang normal College and other research institutions and institutions are all involved, involving history, archaeology, literature, art, computer and other multidisciplinary means. This is a very gratifying situation and is likely to occupy an important position in the development history of Oracle bones.

This major project entrusted by the National Social Science Fund is multidisciplinary and needs the close cooperation of experts in many fields. Many technologies and methods will be tried for the first time in the study of Oracle inscriptions. It is suggested that professional academic journals should be fully used to introduce new scientific research achievements in the process of project research. At the same time, we should listen to the opinions of experts in various sub-topics and summarize them, so as to advance the research work in a targeted, methodical and step-by-step manner.(Li Xueqin)

Solve the problem of low temperature disinfection! China CDC has successfully developed two formulations of chlorine-containing low-temperature disinfectant.

  According to the website of China CDC, after more than five months of repeated exploration and research, China CDC screened out two low-temperature disinfectant formulas from dozens of formulas, and completed the laboratory and field disinfection effect evaluation. In January, 2021, emergency pilot applications were carried out in suifenhe city, Heilongjiang Province and Qingdao, Shandong Province. The results showed that the developed low-temperature disinfectant had simple production process, low raw material cost and reliable disinfection effect at low temperature, which could effectively solve the disinfection problems of low-temperature environment and frozen goods packaging in the northern alpine region.

Shaoguan’s first cross-border e-commerce B2B export business declaration was successful, and the first batch of goods completed export customs clearance in 9 minutes.

  Recently, Shaoguan’s first cross-border e-commerce B2B export was successfully declared. Shaoguan Haoda Supply Chain Management Co., Ltd. successfully declared a batch of "protective films" with a value of US$ 54,000 using this model. The whole export customs clearance time takes only 9 minutes from declaration to release.

  Cross-border e-commerce B2B export is called "cross-border e-commerce business-to-business export", which means that domestic enterprises transport goods to overseas enterprises or warehouses through cross-border logistics, and enterprises transmit relevant electronic data according to customs requirements, and complete transactions through cross-border e-commerce platforms. This trade model enjoys the convenience of full informationization of customs declaration, adding convenient declaration channels and giving priority to inspection, which can effectively improve the efficiency of cross-border e-commerce retail export and help improve the foreign trade competitiveness of small and medium-sized enterprises.

  Faced with the impact of the epidemic, Shaoguan Customs and Shaoguan Municipal Bureau of Commerce have solidly promoted the work of stabilizing foreign trade and promoting growth, actively promoted the national customs clearance integration declaration model to enterprises, provided guidance to enterprises throughout the process of registration and filing, port opening and data declaration, and successfully attracted enterprises to return to their territories for declaration, which effectively boosted foreign trade growth.

  The person in charge of Shaoguan Haoda Supply Chain Management Co., Ltd. said that with the strong support of Shaoguan Customs and Shaoguan Municipal Bureau of Commerce, the company successfully opened the first cross-border e-commerce B2B export business in Shaoguan, and experienced the bonus of fast and convenient customs clearance in Shaoguan, and the operating cost of the enterprise was greatly reduced. The company expects that the export value will reach 70 million US dollars during the year.

  In the future, Shaoguan Customs will fully support the development of new formats, including B2B export of cross-border e-commerce, support customs clearance facilitation measures, actively promote the diversified development of Shaoguan’s foreign trade, provide a new platform for stabilizing foreign trade and inject new kinetic energy.

Shanghai "Tianjiacha" Teahouse was investigated, and the victim students got back the cheated money.

  Weibo said that two Japanese students encountered "saucers" when visiting the Yuyuan Scenic Spot in Shanghai. Weibo screenshot

  The Beijing News (Reporter Lin Feiran, Li Xin, Zhang Jian, intern Zhang Rui) On April 7th, a netizen posted a Weibo saying that on the afternoon of the 6th, two Japanese students were taken to the Yuyuan Teahouse on the second floor of No.229 Jinling East Road for tea when they were visiting the Yuyuan Scenic Area in Shanghai. "When I checked out, I was told that the tea fee was 48 yuan’s bite. A total of more than 2,100 yuan was spent, and all the cash of more than 1,000 yuan was forcibly hollowed out. "

  At 7 o’clock last night, "Shanghai Huangpu", which was certified as the official WeChat public account in Huangpu District, sent a message saying that the teahouse involved had been investigated and dealt with. Once the illegal facts are verified, they will be severely punished according to law.

  The day before, "Shanghai Huangpu" announced that the money had been returned after the deceived students reported to the police.

  event

  Invited to tea, told 2000 yuan at checkout.

  Weibo said that two Japanese students encountered "saucers" when visiting the Yuyuan Scenic Spot in Shanghai. According to the receipt of the case (incident) of Shanghai Public Security Bureau published in Weibo, at about 15: 45 on April 6, two parties (Japanese students) came out of Yuyuan Station of Shanghai Metro Line 10 and met a man and two women, who were asked to help them take photos.

  These three people invited two parties to have dinner together. Subsequently, the two were taken to Yuyuan Teahouse on the second floor of No.229 Jinling East Road for tea, and were told that they spent a total of 2,000 yuan at checkout. More than 1,000 yuan in the wallets of the two parties was forcibly taken away. Afterwards, Japanese students reported the case to the Bund Police Station of Huangpu Branch of Shanghai Public Security Bureau.

  On the evening of April 7, the netizen claimed that two students got back the cheated money at the Bund police station, but was asked to stop here.

  respond

  The store has returned the consumption amount to the party concerned.

  At 6: 44 pm on April 8, "Shanghai Huangpu" issued a statement on the situation of chopping off customers in Yuyuan Teahouse, No.33 Henan South Road, responding that on April 7, after the parties asked the police for help, the store had returned more than 1,000 yuan spent by them through work.

  The article also said that on the morning of April 8, Huangpu District Market Supervision Bureau conducted an on-site inspection on the second floor of No.33 Henan South Road. After investigation, the "Yuyuan Teahouse" at No.229 Jinling East Road reflected by netizens is actually located in Room 206, No.33 Henan South Road, Huangpu District, Shanghai. The enterprise is "Shanghai Yiketing Tea Co., Ltd.".

  According to industrial and commercial data, Shanghai Yiketing Tea Co., Ltd. was established on April 12, 2013 with a capital injection of 30,000 yuan. Its business scope covers prepackaged foods, bulk food, direct imported food, arts and crafts, tea sets, etc. Its legal representative is Hua Jingqin, and it is registered by Huangpu District Market Supervision Administration.

  Last night, the Beijing News reporter got in touch with Mr. Guo Dong, a shareholder of the company. He said on the phone that it was not 48 yuan’s tea, but he was not the main person in charge now, and then hung up.

  At 7 o’clock last night, "Shanghai Huangpu" announced that after investigation and evidence collection by Huangpu District Market Supervision Bureau, "Yuyuan Teahouse" was suspected of violating the Consumer Protection Law and other relevant laws and regulations, infringing on the legitimate rights and interests of consumers, and has now filed a case for investigation. Once the illegal facts are verified, they will be severely punished according to law.

  In addition, the relevant law enforcement departments in Huangpu District remind consumers to pay attention to whether the purchased goods (services) are clearly marked when consuming, so as to avoid the price being tricky, and at the same time, be sure to ask the merchants for invoices or consumption vouchers, so as to facilitate the rights protection in case of consumer disputes.

  Statement 1

  If it involves saucer fraud, can I get a refund?

  Han Xiao, a lawyer of Beijing Kangda Law Firm, believes that if the tea provided by the teahouse where the "saucer" is located does not match the price list, or Japanese students order directly from the saucer when they consume, and are required to pay a high consideration when they pay the bill, then the behavior of the saucer is suspected of criminal fraud; If the saucer has forced payment during the transaction, it is suspected of forced transaction.

  Judging from the current information, the amount involved is 1000 yuan, which has not yet reached the sentencing standard for fraud (3,000 yuan) or forced trading (2,000 yuan) in the Criminal Law. Therefore, in addition to refunding money, according to the relevant provisions of the Law on Public Security Administration Punishment, the saucer is most likely to face administrative punishment, that is, detention for less than 10 days and a fine of less than 500 yuan. "If the police find other victims after investigation, they may be criminally punished."

  Statement 2

  Does Japanese student status affect rights protection?

  Han Xiao said that according to the "Measures for Punishment of Infringement on Consumer Rights and Interests", when operators make false or misleading propaganda on goods and services, the administrative department for industry and commerce will punish them in accordance with the Consumer Protection Law. According to the circumstances, you can impose a warning, confiscate the illegal income and impose a fine of less than ten times the illegal income.

  "China’s civil law, criminal law and administrative law all stipulate the principle of territoriality, that is, events that occur in China are subject to Chinese laws." Han Xiao said that although the victims in this incident were Japanese students, it did not affect their rights in China through civil, criminal and administrative means. In terms of rights protection, according to the current report, Japanese students can call the police to coordinate and resolve disputes, or they can ask the saucer to compensate themselves for personal and property losses caused by this incident through civil procedures.

  In recent years, we have experienced "sky-high" events.

  In addition to 48 yuan’s high-priced tea, in recent years, the media reported many "high-priced" events. For example, a dish of "sky-high tofu" at 368 yuan, "sky-high horse riding" at one yuan per second, a bowl of casserole rice congee in 100 yuan, a dried apricot in 8.8 yuan and so on.

  In this regard, Zhang Lingyun, vice president of the School of Tourism Management of Beijing Union University, once suggested that the government should take the lead in establishing a supervision consortium for tourism, public security, industry and commerce, price and other departments. We can set up a government to guide prices, seriously investigate and deal with negative tour fees, and seriously rectify the catering market.

  A cheap shrimp in 38 yuan.

  Event: During last year’s National Day, some netizens broke the news that they encountered a guest-killing incident while eating in Qingdao. When ordering, the boss confirmed that 38 yuan had a "sea prawn", and when checking out, it became a 38 yuan, and the asking price for a plate of prawns was more than 1,500 yuan.

  Results: Qingdao Municipal Price Bureau and others found out that although the food provided by the food stall was clearly marked, it was not standardized and was suspected of misleading consumers. The hotel involved was fined 90,000 yuan and ordered to correct it immediately.

  398 yuan a catty of sky-high fish

  Event: In February this year, Weibo, a Chen Yanfa from Jiangsu, said that after going to Harbin for the Spring Festival and being taken to the "North Shore Wild Fish Village" restaurant by a tour guide, the bill bill showed that the price was 10,302 yuan and the unit price was 398 yuan.

  Results: The local government departments found that there were some behaviors, such as selling farmed mandarin fish as wild mandarin fish, and failing to apply for renewal of the Catering Service License on time. The business license of the hotel involved was revoked and a fine of 500,000 yuan was imposed.

  894 yuan sky-high mushroom stew chicken

  Event: On October 2 last year, a Shanxi tourist said that he was taken to a restaurant for a farmhouse banquet by a "black tour guide" in Laoshan Scenic Area, and finally spent 2,300 yuan, including 894 yuan for a mushroom stew chicken.

  Results: Laoshan Scenic Area ordered the person in charge of the hotel to suspend business for rectification, apologized to the tourist, and compensated the tourist for all the losses.

Samsung released the roadmap of advanced chip technology: the new version of 2 nm process will be mass-produced in 2027, and the development and production time will be shortened by 20%.

On June 13th, Samsung Electronics announced the progress of many chip technologies in the future at the "Samsung OEM Forum in 2024", and said that its OEM business plans to provide customers with one-stop services, and integrate its number one storage chip, OEM and chip packaging services in the world, so as to produce artificial intelligence chips faster and take advantage of the artificial intelligence boom.

Samsung said that customers only need one communication channel to dispatch Samsung’s memory chip, wafer manufacturing and packaging teams at the same time. Compared with the existing technology, the time from research and development to production is expected to be shortened by 20%.

Siyoung Choi, president and general manager of Samsung Wafer Manufacturing, said: "We really live in the AI ? ? era-the advent of generative AI is completely changing the technological landscape."

Samsung has launched fierce competition with TSMC in the field of chip foundry, hoping to catch up in the field of AI foundry. Samsung introduced an advanced process called BSPDN, and moved the power interconnection to the back of the chip. This technology improves power, performance and area, and can be used for AI chips and high-performance computing. Compared with the first generation of 2 nm process, the voltage is significantly reduced, and the mass production time is in 2027. Korean media pointed out that there is no precedent for commercialization in the world.

Samsung also promotes the architecture of all-around gate transistor (GAA). As the chip becomes more and more refined and even breaks through the physical limit, GAA is regarded as an important factor to continue to manufacture more powerful chips for AI. Competitors such as TSMC are also developing GAA chips, but Samsung started earlier and said it plans to mass-produce the second-generation 3-nanometer chips using GAA in the second half of this year.

According to Samsung Electronics, the 1.4-nanometer chip technology is progressing smoothly. From the perspective of efficiency and production yield, it is expected to be mass-produced as scheduled in 2027.

Samsung predicts that the global chip industry revenue will increase to 778 billion US dollars by 2028, driven by AI chips.

Marco Chisari, executive vice president of wafer manufacturing and marketing of Samsung, said that Samsung believes that OpenAI CEO Altman’s rough forecast of the surge in demand for AI chips is true. Earlier, foreign media reported that Altman had told TSMC executives that he hoped to build about 30 new fabs. Samsung Electronics predicts that by 2028, the list of AI-related customers will increase fivefold and revenue will increase ninefold.

According to Jibang’s estimation, Samsung Electronics’ market share in wafer manufacturing fell to 11% in the first quarter of this year from 11.3% in the previous quarter, while TSMC increased from 61.2% to 61.7% in the same period.

It is worth noting that TSMC, the main competitor of Samsung Electronics, is gaining momentum. Huang Renxun, CEO of NVIDIA, has agreed that TSMC should raise prices. Barclays analysts are optimistic that the upcoming mass production of 2 nm applications will be faster than expected. Barclays believes that the leading position of semiconductor applications has shifted from smart phones to data centers. "The demand for 2 nanometers is strong, which is a big advantage for TSMC." Barclays raised the target share price of TSMC ADR from US$ 150 to 170 yuan, maintaining the "overweight" rating.

Report on the vitality of the Yangtze River ①: The health status of the Yangtze River basin presents regional differences.

On September 27th, on the day of World River Day, the press conference of "Taking the Pulse of the Yangtze River" and "Yangtze River Vitality Report 2020" (hereinafter referred to as "Report") co-sponsored by WWF and The Paper was held in Shanghai.

In this activity, WWF, together with the Institute of Hydrobiology of Chinese Academy of Sciences, the Institute of Geographical Sciences and Resources of Chinese Academy of Sciences, the Nanjing Institute of Geography and Lakes of Chinese Academy of Sciences, the Yangtze River Academy of Water Conservancy Commission, the Environmental Planning Institute of the Ministry of Ecology and Environment, the Key Laboratory of Yangtze River Water Environment Education Department of Tongji University, the School of Water Conservancy and Hydropower of Wuhan University, and the Suzhou Institute of Environmental Innovation of Tsinghua, jointly released the Yangtze River Vitality Report 2020.

It is understood that WWF and the above eight research institutes started the project in 2018. The purpose is to provide a systematic and objective report on the health diagnosis of the Yangtze River, provide policy advice for strengthening the ecological environment protection of the Yangtze River basin and implementing the green development strategy of the Yangtze River Economic Belt, provide policy suggestions for the protection and management of the Yangtze River ecosystem, and stimulate and promote different stakeholders to actively participate in the Yangtze River protection.

Kyle Rambotti, Global Director-General of WWF, said in the preface that as the first complete basin-level index in the world, the Yangtze River Vitality Index is also an innovation, and its concept connotation and evaluation method are expected to be further promoted worldwide. After all, for the major rivers in the world, we can’t reverse the trend of freshwater ecosystem loss and biodiversity decline until we better understand their vitality.

As the core of the report, Kyle Rambotti said that a complete basin-level index in the world is the Yangtze River vitality index, which sorts out many indicators and selects representative, indicative, concise, traceable and sustainable indicators to comprehensively reflect the health status of the Yangtze River freshwater ecosystem from three dimensions: hydrology, water environment and water ecology. The main conclusion of the index evaluation is that the overall health status of the Yangtze River is B-, and it shows regional differences with human activities.

The Paper, as the strategic cooperation media of the project, sent reporters to interview the relevant experts of the research group on the hydrology, water environment and water ecology of the Yangtze River before the report was released, so as to comprehensively interpret the report on the vitality of the Yangtze River.

Hydrological article

Hydrological index should be considered comprehensively.

The report points out that as an important characteristic of freshwater ecosystem, the change of hydrological situation determines the water quality, habitat and biological life history process of rivers. At the same time, the amount of river sediment transport and the change of sediment erosion and deposition significantly affect the biogeochemical cycle, water quality, river-lake relationship and the development of estuary delta, which is of great significance to the function of river ecosystem. The indexes for evaluating hydrological situation in the report mainly include hydrological process indicators and connectivity indicators.

Jin Chen, the leader of the research group of the report and a professor at the School of Water Resources and Hydropower of Wuhan University, told The Paper that the hydrological index is mainly aimed at natural rivers, that is, compared with the era without large reservoirs (before 1980), the higher the index, the closer it is to the natural hydrological process.

He said that at present, the main stream and tributaries of the upper reaches of the Yangtze River (except Chishui River) are not pure natural rivers. Therefore, the hydrological index is not high, which is mainly aimed at natural ecosystems such as fish. For densely populated China, it is necessary to build a reservoir. It cannot be simply said that a high hydrological index is better, and a low hydrological index is not good. "Both human beings and nature need water resources. The high or low hydrological index reflects the difference between human beings and nature in water resources distribution. It is necessary to comprehensively consider the needs of human development and nature protection and make rational distribution and regulation."

Global warming and the development of urban agglomeration affect the hydrological situation.

Besides being influenced by the connectivity between reservoirs and rivers and lakes, climate change also shapes the hydrological situation of the Yangtze River, which is mainly reflected in precipitation and flood events. Li Xin, a member of the research group and a doctor from the National University of Singapore, told The Paper that the report analyzed the impacts of ENSO (El Nio-Southern Oscillation, El Ni? o/La Ni? a and Southern Oscillation) events and global warming on the extreme precipitation index and hydrological core index by correlation analysis.

The results show that ENSO events have a significant impact on the extreme precipitation indexes in the source, upper and middle reaches of the Yangtze River basin. Specifically, La Nina events in ENSO events will generally increase the intensity and frequency of extreme precipitation in the source, upper and middle reaches of the Yangtze River basin, which may lead to an increase in flood risk in the Yangtze River basin. Global warming has a significant impact on the index of extreme precipitation in the middle and lower reaches of the Yangtze River basin, which will generally increase the intensity and frequency of annual precipitation and extreme precipitation events in the middle and lower reaches of the Yangtze River, and may also increase the flood risk in the Yangtze River basin.

Li Xin also stressed that the impacts of global warming and ENSO events on hydrological core indexes in different water resources areas show spatial differences, which indicates that hydrological processes have complex responses to global climate change. He believes that "this requires us to further strengthen the impact assessment of climate change on the regional hydrological cycle process, and constantly improve the ability of the Yangtze River basin to scientifically respond to climate change under the background of" Great Protection of the Yangtze River ".

According to the analysis of the report, the rapid development of urban agglomerations in the middle reaches may lead to frequent floods and an increase in the average flow during the flood season. In this regard, Li Xin explained that "the urbanization process has turned many permeable surfaces into impermeable surfaces, resulting in reduced infiltration, increased surface runoff components and increased peak urban flood discharge".

Nature-based solutions may ease the flood control situation in the Yangtze River.

According to the above analysis of the two experts, it can be seen that climate change, land use and other factors all affect the hydrological situation of the Yangtze River, making the flood control situation in the Yangtze River basin more complicated. This summer, the middle reaches of the Yangtze River once again experienced the test of a big flood. How to alleviate the complicated and severe situation, the report proposes that the solution based on nature should be one of the important means in the future when necessary engineering measures are adopted. Jiang Luguang, one of the technical leaders of the research group and an associate researcher at the Institute of Geographical Sciences and Resources, Chinese Academy of Sciences, explained this scheme in detail.

The World Conservation Union (IUCN) defines "nature-based solution" (NBS) as "an action to efficiently and adaptively respond to social challenges and bring benefits to human welfare and biodiversity through the protection, sustainable management and restoration of natural or artificial ecosystems". Jiang Luguang believes that this is completely consistent with China’s ecological civilization concept of respecting nature, adapting to nature and protecting nature. He told The Paper that there are many concrete manifestations of nature-based solutions, such as ecological restoration, adaptive strategies of ecosystems, and green infrastructure.

Taking the flood situation of Poyang Lake in flood season this year as an example, Jiang Luguang introduced the function of "returning farmland to lake" project to adapt to the natural rhythm of the Yangtze River and promote the harmony between people and water. In the flood season of 2020, some hydrological stations in Poyang Lake experienced the highest flood level in history, and the project of returning farmland to Poyang Lake fully played the role of flood storage and detention for the first time. Returning farmland to lake dikes can store about 2 billion cubic meters of flood water, reducing the water level of the lake by 25-30 cm in flood season, and greatly alleviating the flood control pressure of key dikes (protecting towns or tens of thousands of acres of fertile land).

In addition, the ongoing sponge city construction is also a good "nature-based solution". Sponge city advocates giving priority to the use of natural drainage system and low-impact development facilities in urban development and construction to realize natural accumulation, natural infiltration, natural purification and sustainable water circulation of rainwater, which can not only make full use of the natural restoration ability of water ecosystem, but also be an important means to solve the problem of urban waterlogging. For the Yangtze River basin, sponge city can reduce the adverse effects of drastic changes in the underlying surface of the basin on the runoff and runoff.

Water environment chapter

The water environment index in the middle and lower reaches of the Yangtze River is low.

Freshwater ecosystem is the main receiving place of nutrients and organic matter exported by terrestrial ecosystem. The quality of water environment determines whether freshwater ecosystem can provide clean water resources, and nutritional status plays an important role in shaping biological composition and community structure in freshwater ecosystem. The water environment index of the Yangtze River vitality index is mainly aimed at evaluating the main pollutant indexes.

The report pointed out that the main pollutants affecting the water environment index include industrial wastewater, domestic sewage and agricultural cultivation. When calculating the water environment index, the main basis is the water quality index.

Xu Yanxue of the Environmental Planning Institute of the Ministry of Ecology and Environment explained this. "We selected the water quality monitoring sections of major rivers and lakes in the Yangtze River Basin, and calculated three indicators representing water nutrition and organic pollutants, namely ammonia nitrogen, total phosphorus and permanganate index, and obtained the water environment index of each region (main river reach, main tributaries, four lakes, etc.) and evaluated it. The higher the water environment index, the lighter the water pollution and the better the water quality; The lower the water environment index, the higher the water pollution and the worse the water quality.

Xu Yanxue told The Paper that, after calculation, the overall water environment quality of the Yangtze River basin is at the national middle-upper level. However, from the main stream of the Yangtze River, the water environment index in the middle and lower reaches is relatively low, which is B-.

"The social and economic development in the middle and lower reaches of the Yangtze River is rapid, with concentrated industrial enterprises and active production activities. The typical pollutants discharged into the environment by these enterprises are total phosphorus, ammonia nitrogen and organic matter. The permanganate index reflects the concentration of organic matter in water. Although each enterprise has relevant emission standards to limit the amount of pollutants entering the environment, the total amount of emissions will be relatively high. At the same time, the amount of pollutants produced by agriculture and life and the amount of pollutants brought in by the upper reaches of the Yangtze River will be superimposed, resulting in total phosphorus, ammonia nitrogen and permanganate in the middle and lower reaches of the Yangtze River.

At present, the regulatory system can not accurately locate pollution sources.

According to the analysis of the report, the high concentration of pollutants will lead to the decrease of dissolved oxygen in the water body and affect the growth of aquatic organisms. At the same time, the high concentration of total phosphorus will affect the concentration of total phosphorus in the downstream lake water body, leading to the eutrophication of the lake. The Paper noted that the report made a separate analysis of the vitality indices of the four major lakes in the Yangtze River Basin, namely Poyang Lake, Dongting Lake, Taihu Lake and Chaohu Lake, among which the water environment of the four lakes was the key point.

Taking Taihu Lake as an example, the report explains the water environment crisis faced by the lake and its solutions. Since the cyanobacteria crisis in Taihu Lake in 2007, the state and local governments have done a lot of work on pollutant emission reduction and lake pollution control, and achieved remarkable results, but they still failed to return to the concentration level of nutrient elements in the 1970s and 1980s. Under unfavorable meteorological conditions such as high fever and southeast wind, cyanobacteria still broke out in Taihu Lake in recent years, which still failed to change the nature of algal lakes.

The Paper interviewed Yang Hongwei, deputy chief engineer of Suzhou Institute of Environmental Innovation in Tsinghua, about why Taihu Lake has not achieved remarkable results so far. He first affirmed the governance direction of eutrophic lakes. He believes that from the international experience of lake eutrophication control, the management of eutrophic lakes is a long-term project, and the time scale of 10 years is not enough to fundamentally change the essence of lake eutrophication. Judging from the current measures and effects of water pollution control in Taihu Lake, we have achieved remarkable results, especially the concentration of total phosphorus and total nitrogen has decreased significantly, and the frequency and severity of cyanobacteria outbreaks have also decreased significantly, so there is no deviation in our control direction.

However, he also admitted that although there is no deviation in the direction of governance, the regulatory system still needs to develop towards precision. "The current monitoring system can’t meet the requirements of smaller-scale grid supervision, can’t accurately locate pollution sources, and it is difficult to achieve accurate pollution control. This is also a new requirement for the regulatory system in the next step of precise lake governance."

We should continue to pay attention to the types and toxicity of emerging pollutants in water.

The Paper noted that the report specifically mentioned the emerging pollutants in the Yangtze River. Yang Hongwei told The Paper that emerging pollutants generally refer to substances that have not been related to environmental management policies, regulations or emission control standards, but may be included in the control object according to the assessment of their detection frequency and potential health risks. These substances are not necessarily new chemicals, but usually pollutants that have been in the environment for a long time, but have been discovered in the near future because of their low concentration, their existence and potential harm and the development of detection technology.

At present, emerging pollutants detected in the water environment mainly include endocrine disruptors, drugs, personal care products and other trace organic pollutants. Usually, the detection concentration in the water environment is at the level of ng/L. At this concentration level, it generally does not have acute toxicity, and it mainly produces chronic toxicity to organisms in the Yangtze River and further to human body, which is not enough to achieve long-term toxic concentration. However, it has potential endocrine disrupting properties, teratogenesis, carcinogenesis, mutation and resistance gene changes and other chronic toxicity, so we should continue to pay attention to the types, concentrations, sources, migration and transformation, toxicity of emerging pollutants in water, so as to grasp the hazards of emerging pollutants in water in time and provide reference for the formulation of corresponding environmental management policies and regulations.

Water ecology article

The middle reaches of the Yangtze River are frequently disturbed by various human activities, and the water ecology is the worst.

The water ecological index mainly evaluates the richness, diversity, community structure and habitat of aquatic organisms in the main stream of the Yangtze River and four lakes (Dongting Lake, Poyang Lake, Chaohu Lake and Taihu Lake). Water ecology is a "living" part of vitality, and its index directly reflects whether the Yangtze River still has vitality and how much vitality it has.

Chen Yushun, the technical director of the evaluation of the water ecological status of the main stream of the Yangtze River, a researcher and doctoral supervisor at the Institute of Hydrobiology, Chinese Academy of Sciences, said that the water ecology of the main stream of the Yangtze River is generally at the B- level. That is to say, on the whole, the water ecology of the Yangtze River has been at an unhealthy level, which shows that the Yangtze River is really ill. Among them, the water ecological index in the middle reaches is the worst.

It is embodied in the decrease of fish species, natural fishery catch and early fish resources. Chen Yushun said, "The number of fish species in the middle reaches of the Yangtze River has decreased by 36 from 97 in the past, the number of endemic fish species has decreased by 16 from 38 in the past, the number of threatened fish species has decreased by 11 from 16, the number of finless porpoises has decreased from 902 in the past to 193 now, the natural fishery catch has decreased from more than 400,000 tons in the past to 80,000 tons now, and the early fish resources have decreased from 6.7 billion in the past to 9 now.

Chen Yushun further explained this. "Due to the hydropower development in the upper reaches of the Yangtze River and its tributaries, and the interference of human activities such as fishing, shipping, sand mining and industrial and agricultural development in the middle reaches of the Yangtze River, the middle reaches are greatly affected by the superposition. Such as the change of hydrological situation, the decrease of sediment, the utilization of beaches, the reproduction of aquatic organisms such as fish, the degradation and loss of key habitats for growth, and the serious lack of bait resources. Coupled with the direct and indirect effects of overfishing, the above indicators in the middle reaches of the Yangtze River are very low, which in turn affects the comprehensive index of water ecology in the middle reaches of the Yangtze River.

In order to ensure the effect of fishing ban, ecological monitoring should be strengthened

According to Chen Yushun’s description, the biological resources of the Yangtze River are declining and the biodiversity is declining, so it is urgent to "ban fishing in the Yangtze River for ten years". In order to effectively alleviate this crisis, the state has issued a series of relevant documents and notices to make arrangements for a total ban on fishing.

On July 15, 2020, Yu Kangzhen, Vice Minister of Agriculture and Rural Affairs of China, said at the policy briefing held by the State Council Office that on January 1 this year, 332 aquatic life reserves in the Yangtze River Basin had been completely banned on schedule, and the fishing ban in key waters in the Yangtze River Basin would be implemented for 10 years from January 1, 2021.

For the 10-year cycle, Chen Yushun explained to The Paper that 10 years is a relative value, and fish can complete a certain breeding cycle, which should also be a tentative period. During this period, most aquatic organisms can have a relatively long period of proliferation and population recovery. However, in these 10 years, it is also necessary to adjust other stress factors, carry out habitat restoration and restore biological resources at the same time.

In order to effectively monitor the effect of the ban on fishing, Chen Yushun suggested that the relevant departments should open up a green channel for scientific investigation when carrying out a comprehensive ban on fishing, so as to ensure the availability of scientific research vessels and the simplicity of handling fish fishing licenses. In this way, scientists and fishery resource managers can really work in the same direction to jointly promote the ecological protection of the Yangtze River.

The ecology of the four lakes in the Yangtze River is not optimistic as a whole.

According to the report, Dongting Lake, Poyang Lake, Chaohu Lake and Taihu Lake are the four largest freshwater lakes in the Yangtze River Basin, among which Dongting Lake and Poyang Lake directly connect with the Yangtze River. These four shallow-water and fresh-water lakes play a huge ecosystem service function in terms of water regulation, material supply, providing biological habitat, maintaining biodiversity and keeping clean water sources, and play an extremely important role in protecting the water ecological health of the Yangtze River basin and maintaining the vitality of the Yangtze River.

Junfeng Gao, the technical director of the ecological assessment of Sihu Lake, a researcher and doctoral supervisor of Nanjing Institute of Geography and Lakes, Chinese Academy of Sciences, told The Paper that according to the assessment results, the current water ecological indexes of Dongting Lake and Poyang Lake are B-, Taihu Lake is C- and Chaohu Lake is D. That is, the water ecological health of Dongting Lake and Poyang Lake is in an upper-middle state, Taihu Lake is in an upper-middle state, and Chaohu Lake is in a lower-middle state. On the whole, the water ecological state of the four lakes is not optimistic, and the problems in Taihu Lake and Chaohu Lake are particularly serious.

Poyang Lake should be put in the first place in the differential treatment of the four lakes

As for how to harness the ecology of the Four Lakes, Junfeng Gao thinks that the protection and harness countermeasures are different because of the great differences in the natural geographical conditions, the influence degree of human activities and the water ecological problems faced by the Four Lakes.

He pointed out that the Dongting Lake basin should maintain the river-lake connectivity and the original hydrological rhythm of Tongjiang Lake, control the amount of pollutants entering the lake in the basin, strengthen the collection and treatment of urban domestic sewage, and control the agricultural non-point source pollution discharge. Poyang Lake basin should pay attention to the protection of biological species population and diversity, strengthen the protection of its habitat, and strictly supervise and manage nature reserves.

For Taihu Lake and Chaohu Lake, where the problem is particularly serious, it is also necessary to treat them differently. Junfeng Gao said that the Taihu Lake Basin should strengthen pollutant discharge control, control the total phosphorus flux into the lake, and strengthen the prevention and control of cyanobacteria bloom in the lake water. Chaohu Lake Basin should control the pollution of Nanfeihe River, Shiwuli River and Paihe River, strengthen the construction of urban environmental infrastructure in Hefei, improve the sewage collection rate and strengthen the level of nitrogen and phosphorus removal. Strengthen the prevention and control of cyanobacteria bloom in the lake area and establish a monitoring and early warning mechanism for cyanobacteria bloom in Chaohu Lake.

Among the four lakes, Junfeng Gao particularly emphasized the management of Poyang Lake. He said that Poyang Lake is the largest of the four lakes and is closely related to the main stream of the Yangtze River. Poyang Lake has rich ecosystem types, huge ecosystem service capacity, rich habitat types and biodiversity, and unique hydrological rhythm, which provides rich food and good food availability for various migratory birds. Its water ecological health quality has the most obvious effect on enhancing the vitality of the Yangtze River, so it is also the most important lake among the four lakes. The protection and restoration of Poyang Lake water ecology should be placed in the first place of the four lakes. 

Provide financial support for science and technology enterprises in the initial stage, so that the seeds of innovation can germinate competitively.

  Venture capital, seed funds actively lay out emerging industries and future industries, and "stock loan and debt guarantee" has strengthened the linkage to solve the financing bottleneck of technology enterprises … Nowadays, financial products continue to innovate, and fiscal and tax support continues to increase. In the past, start-up technology enterprises that faced financing problems because of small scale, light assets and difficult valuation have received more help. A few days ago, the reporter walked into a number of technology-based enterprises and felt the enthusiasm for innovation.

  Help the early, the small and the excellent, and the fund will take good care of the project growth.

  At the end of August, the "Quantum Vision" project in cooperation with Anhui Science and Technology Museum was successfully delivered. Hu Wei, executive director of Hefei Hanhai Quantum Technology Co., Ltd., breathed a sigh of relief: "Thanks to the help of the seed fund, we have the confidence to take this project."

  Two years ago, Hu Weicheng, a researcher at China University of Science and Technology, established Hanhai Quantum according to the policy that universities give scientific researchers the ownership of scientific and technological achievements. In the early days of the establishment of this technology-based enterprise, the dilemma of lack of funds, equipment and space once left the founding team at a loss.

  In May last year, in the roadshow of the achievement project of Hefei Science and Technology Achievement Transformation Special Class, Hu Wei showed the company’s technology, which successfully attracted the attention of Dean Wong, the leader of the second group of Hefei Science and Technology Achievement Transformation Special Class. As the deputy general manager of Hefei Kechuang Group, the operation manager of Hefei seed fund, Dean Wong made a preliminary agreement with the scientific research team of Hanhai Quantum Company to invest 2 million yuan in seed fund after confirming the innovation and practicability of the project.

  The blessing of seed fund not only helped Hu Wei enterprises tide over the difficulties, but also incited other capitals to join. "The enterprise has just been established with no profit and financing difficulties. After getting the seed fund, it not only solves the current financial problem, but also makes our follow-up financing much easier. " Hu Wei told reporters that they are currently negotiating with Hefei Industrial Investment Promotion High-tech Venture Capital Fund Partnership, and will soon get another investment of 3 million yuan.

  In 2022, Hefei set up a seed fund with a total scale of 500 million yuan to provide financial support for "original innovation, source innovation and integrated innovation". "Different from other funds, seed fund investment projects are in an earlier stage, like’ sowing’." Dean Wong said that the operation process should be evaluated according to the whole life cycle of the fund, and the maximum loss of the fund should not exceed 50%. Up to now, Hefei Seed Fund has reviewed 108 projects, of which 97 projects have passed the establishment meeting, and the approved investment amount exceeds 160 million yuan.

  Since the beginning of this year, aiming at strategic emerging industries such as high-end equipment manufacturing, integrated circuits, biomedicine and big health, Hefei Seed Fund has signed 29 loan projects, totaling 53.5 million yuan, achieving full coverage of key industries. Today, the city has built a "fund jungle" of "government-guided parent fund+seed/angel/science and technology innovation fund+market-oriented fund", which has injected impetus into the high-quality development of local industries.

  "Science and technology enterprises in the seed stage and initial stage have great development potential, but they also have problems such as high commercial risks and low credit level, and it is often difficult to obtain funds from traditional financing channels. As a professional organization, angel investment, seed fund and other investments are of great significance to start-ups, which can provide necessary financial support for enterprises to carry out R&D and marketing activities, and also standardize corporate governance and improve project success rate through business guidance. " Tian Lihui, dean of the Institute of Financial Development of Nankai University, said.

  In the 6th (2023) China Medical Device Innovation and Entrepreneurship Competition, Qingdao Jianxin Medical Technology Co., Ltd. was awarded the special project of the National Key R&D Plan of the Ministry of Science and Technology, and was selected as the first batch of projects to be invested in the "Fruitful Gold" of Qingdao … After just one year of establishment, Qingdao Jianxin Medical Technology Co., Ltd. achieved rapid development.

  In 2022, Feng Qingyu founded Jianxin Medical. With ideas and technology, he and his team came to Qingdao High-tech Zone Road Show in Shandong Province. "At first, we just wanted to have a platform to promote our products. I didn’t expect to be valued by the high-tech zone and get continuous financial support." Feng Qingyu said.

  In recent years, Qingdao has devoted itself to building a global venture capital center, promulgated the Management Measures of Qingdao New and Old Kinetic Energy Conversion Guidance Fund and the policy of "Qingdao Venture Capital Ten Articles", optimized the government guidance fund policy system with the government guidance fund as a link, and activated the endogenous motivation of venture capital institutions to invest in Qingdao projects through a series of combination punches such as improving policy incentives and building a capital public platform.

  "With the investment of government investment funds, the interest of various financial institutions in us has greatly increased, financing has been much smoother, and more scientific research results have been promoted." Feng Qingyu told reporters that they not only received 30 million yuan of government investment fund, but also 10 million yuan of credit support from Qingdao High-tech Sub-branch of Shanghai Pudong Development Bank, completed tens of millions of yuan of A round financing, and received 5 million yuan of investment from Qingdao "Fruit Gold".

  "At present, local funds have developed rapidly, forming a professional and diversified development trend, actively promoting the development of strategic emerging industries and promoting R&D and innovation of high-quality enterprises." Tian Lihui said.

  It is understood that the National Guiding Fund for the Transformation of Scientific and Technological Achievements established by the Ministry of Finance and the Ministry of Science and Technology has set up a total of 36 sub-funds, which has driven social capital investment to exceed 100 billion yuan at the project level, with an amplification ratio of 1: 18. Among the invested enterprises, small and medium-sized enterprises account for more than 90%, and 36 enterprises have been listed in science and technology innovation board.

  Tian Lihui believes that in order to better support the development of angel investment, seed funds and industrial funds, the government needs to continue to play a good guiding role and provide necessary support and encouragement policies. At the same time, by setting up guiding funds, providing tax incentives and relaxing investment restrictions, we will encourage and guide more social capital to enter related fields, strive to train professionals and establish cooperation mechanisms to jointly promote scientific and technological innovation and industrial upgrading.

  "Don’t look at bricks to see patents", credit product innovation promotes the transformation of scientific and technological achievements

  Not long ago, Shandong Huajian Testing Co., Ltd. received a national patent certificate, and its research and development of "Staphylococcus aureus detection equipment" was recognized. This is the fourth patent certificate received by Shandong Huajian within three months.

  "The company has developed so well, thanks to the help of Linyi High-tech Zone." Wei Kepeng, deputy general manager of Shandong Huajian, said that at the end of last year, the company introduced a group of scientific research talents to focus on related technologies and needed to purchase equipment such as liquid chromatography-mass spectrometry and liquid chromatography.

  "The purchase of equipment is nearly 4 million yuan, which is not a small expense for a start-up like us." Wei Kepeng said frankly, "Small and medium-sized science and technology enterprises have no heavy assets to mortgage, which does not meet the traditional loan conditions."

  When the development of the enterprise is in a bottleneck, the staff of the Science and Technology Innovation Office of Linyi High-tech Zone made a door-to-door investigation, which brought good news.

  According to the staff, Linyi High-tech Zone implemented the "Science and Technology Innovation Financial Environment" optimization and promotion action, introduced the enterprise innovation points system, scored according to the enterprise innovation development indicators, and took the enterprise innovation points as a reference, made accurate policies in different categories and at different levels, and carried out credit evaluation and credit enhancement for small and medium-sized science and technology enterprises. At present, it has established cooperation mechanisms with a number of financial institutions to accelerate the development of special technology and finance products for "innovative points loans". Linyi High-tech Zone has also established service mechanisms such as financing risk compensation, loan discount and guarantee subsidy for small and medium-sized science and technology enterprises in the initial stage, and built a platform for cooperation between government, banks and enterprises.

  After listening to the policy, Wei Kepeng repeatedly praised it. Finally, after evaluation, Shandong Huajian scored a high score in innovation points, and successfully won a loan of 5 million yuan from Linyi High-tech Sub-branch of China Construction Bank.

  "In the past three years, Linyi High-tech Zone has comprehensively utilized various means such as scientific and technological equity investment, loans for transforming scientific and technological achievements, intellectual property pledge financing, and credit loans for small and medium-sized scientific and technological enterprises, and has helped more than 20 small and medium-sized scientific and technological enterprises in the region to obtain various financing loans of more than 300 million yuan." Hu Deli, director of the Science and Technology Innovation Office of Linyi High-tech Zone, introduced.

  Up to now, more than 100 national high-tech zones and more than 30 provincial high-tech zones have comprehensively promoted the enterprise innovation points system, and more than 100,000 enterprises have been included in the points evaluation. In 2022, integral enterprises received nearly 120 billion yuan in credit.

  "Looking at patents without looking at bricks", anchoring the scientific and technological characteristics of enterprises to carry out institutional innovation, has activated a pool of spring water in technology and finance.

  In Hefei, Anhui Province, in order to alleviate the financing difficulties of small and medium-sized science and technology enterprises, the High-tech Zone, together with four pilot banks, such as Industrial and Commercial Bank of China and Huishang Bank, launched the "loan-investment batch linkage" business, and recommended the technology enterprises that the state-owned holding fund has invested and intends to invest in batches. Since the pilot, 456 enterprises have been recommended, with a total credit of 730 million yuan and a total loan of 573 million yuan. According to the relevant person in charge of the Finance Bureau of Hefei High-tech Zone, now, relying on the platform of "regional economic brain", the local government has developed a series of application tools such as co-creation vouchers, market exchange, financial supermarkets and policy links for enterprises to provide more convenience.

  In Zhejiang, CITIC Bank launched the "Kechuang e-loan", a credit product of less than 10 million yuan, which was applied and approved online without mortgage; For enterprises with strong scientific and technological attributes, capital operation and listing expectations, credit loans of up to 30 million yuan will be given by adopting the credit card approval model; For the core talents in the management team of science and technology enterprises, a "talent loan" product with talents as the mainstay and supplemented by business and financial judgment will be launched, with a maximum amount of 30 million yuan.

  In Shanghai, Industrial Bank improved its financial service system based on the industrial park, gave full play to the advantages of "firm+investment bank", and provided financial support for small science and technology enterprises in the supply chain and industrial chain. By the end of 2022, there were 26,906 customers in the Industrial Bank Shanghai Branch, an increase of 4,450, accounting for 61%.

  Tian Lihui believes that supporting the innovation and development of start-ups requires continuous innovation of financial products and services. In the future, we should continue to improve technology and finance, supply chain finance, financing guarantee, loan insurance and other different types of products and services to meet the needs of different types of enterprises and provide more abundant financing channels for start-ups.

  Fiscal and tax support and supporting services are in place to reduce the burden for innovation and entrepreneurship.

  Simplify the registration procedures, provide preferential rent, extend the contract period, give entrepreneurship subsidies, technological innovation subsidies, talent introduction subsidies, and introduce a series of preferential tax policies … All measures are taken to reduce the burden on start-ups and support the development of innovation and entrepreneurship.

  Support talent introduction and technical research, and all kinds of subsidies are multi-pronged.

  According to Yong Zhi, general manager of Hefei Zhuohua Intelligent Technology Co., Ltd., the rapid growth of the company is inseparable from financial support.

  "In the early days of the company’s establishment, it was necessary to spend money everywhere to decorate factories, purchase equipment and attract talents. At that time, the pressure of purchasing raw materials was great, and the capital turnover was particularly difficult. Fortunately, as a national high-tech enterprise, it can enjoy financial subsidies. The city gave a subsidy of 130,000 yuan to the research and development expenses of small and medium-sized science and technology enterprises, and a subsidy of 400,000 yuan to high-tech enterprises. These two funds helped us a lot. " Yong Zhi said.

  The talent apartment provided in the area also solved the housing problem of Wei Ankun, the company’s R&D director. After graduation, he stayed in Hefei and moved into a talent apartment. The monthly rent was only in 500 yuan.

  In order to effectively meet the development needs of start-ups, Hefei High-tech Zone has specially issued "Several Policies and Measures for Building a World-leading Science and Technology Park to Further Support Scientific and Technological Innovation", and issued 16 specific support policies in supporting the construction of high-level innovation platforms, supporting the introduction of high-level talent teams, and promoting the transfer and transformation of scientific and technological achievements.

  Tax incentives to encourage the development of entrepreneurial platforms and venture capital enterprises.

  "Our company mainly provides incubation services for technology enterprises. As of August this year, we enjoyed tax concessions including value-added tax, property tax and land use tax of more than 750,000 yuan." The Science and Technology Park built and operated by Yinxing Investment Group Co., Ltd. has a national-level technology business incubator, a municipal-level creative space and a district-level technology business accelerator. Jiang Yuyan, the company’s financial director, said, "The operation and maintenance costs of the incubator are high, and the preferential tax and fee policies have been implemented in time to reduce the operating pressure of enterprises and support us to better serve innovative enterprises. At present, the company has invested in more than 10 start-ups and 85 small and medium-sized enterprises. "

  Recently, the finance and taxation department issued an announcement to continue to implement the tax policies related to science and technology business incubators, university science parks and Zhongchuang Space. Property tax and urban land use tax shall be exempted for national and provincial science and technology business incubators, university science parks and national record creation spaces, as well as for real estate and land provided to incubatees for free or through leasing; The income from providing incubation services to incubating objects shall be exempted from VAT.

  "Actively establishing incubators and accelerator platforms can provide office space, financial support, legal advice, talent introduction and other services for start-ups, and form a professional environment to help start-ups develop and grow better." Tian Lihui believes that the financial system that supports the innovation and development of start-ups should be diversified and multi-level. It is necessary to develop various investment institutions such as angel investment, venture capital and private equity. At the same time, it is necessary for the government, financial institutions and other parties to deepen cooperation and provide start-ups with all-round services and assistance.

Personal protection health education information in heavily polluted weather

1. Heavy polluted weather with PM2.5 as the primary pollutant is harmful to health.

Interpretation: Polluted weather refers to the phenomenon of air pollution caused by the accumulation of pollutants in the air under unfavorable meteorological conditions such as no wind, inversion and high humidity. Heavily polluted weather generally refers to the air pollution phenomenon that the air quality index is greater than 200, that is, the ambient air quality reaches the level of heavy pollution and above. Heavy polluted weather with PM2.5 as the primary pollutant is commonly known as "smog". When heavy pollution weather may occur, the local government will issue early warning information.

PM2.5 in the atmosphere is the general name of all particles with a diameter less than or equal to 2.5 microns, and its diameter is about one twentieth of that of hair. PM2.5 can stay in the atmosphere for a long time, is not easy to remove, and can adsorb a variety of harmful substances, easily inhaled into the deep respiratory tract, and some components can also enter the blood, which is harmful to human health.

At present, the sources and composition of PM2.5 are different in different regions of China. The main sources of PM2.5 include industrial emissions, coal-fired emissions, motor vehicle exhaust, garbage incineration, rural straw burning, construction and road dust. In addition, open-air barbecues, food cooking, forest fires and volcanic eruptions will also cause PM2.5 to accumulate in the air. Indoor PM2.5 is not only from outdoor air pollution, but also from indoor smoking and food cooking.

Second, the health hazards of heavily polluted weather include acute and chronic.

Interpretation: The acute harm of heavily polluted weather with PM2.5 as the primary pollutant is mainly manifested in symptoms such as cough, sore throat and eye irritation caused by inhaling pollutants in a short time. Heavy polluted weather can also induce acute attack or aggravation of chronic diseases such as bronchial asthma, chronic obstructive pulmonary disease, cardiovascular and cerebrovascular diseases. Seek medical attention if necessary.

Chronic hazards mainly include the effects on respiratory system and cardiovascular system. According to the World Health Organization, long-term and persistent heavy polluted weather can increase the risk of respiratory diseases such as asthma, bronchitis, chronic obstructive pulmonary disease, lung cancer and cardiovascular diseases such as hypertension, coronary heart disease and stroke. Heavy polluted weather can also affect people’s mood.

Third, when there is heavy pollution weather, personal protection should be done.

Interpretation: The public should pay attention to the local heavy pollution weather forecast and early warning information.

In case of heavily polluted weather, the exposure should be reduced as much as possible, and the main measures include:

1. The public should reduce outdoor activities.

2. Children, pregnant women, the elderly, patients with cardiovascular diseases and respiratory diseases should try to avoid outdoor activities.

3. Close the doors and windows in time, don’t smoke indoors, in addition, avoid cooking and other behaviors that may aggravate indoor air pollution. If no new fan is installed indoors, try to avoid the peak period of pollution according to the local air pollution situation, and open the window for ventilation once or twice a day for 10-20 minutes each time. If there are many people in the room and the space is small, the number of windows should be increased appropriately.

4. If conditions permit, air purification equipment can be used.

5. If you have to go out, you should minimize the time and intensity of outdoor activities and wear qualified masks; Wash your face and bare skin when you come back from going out.

Fourth, the correct choice and wearing of masks can reduce the impact of PM2.5 on human health.

Interpretation: The standard mask has good protective performance, which can effectively filter or block PM2.5 and greatly reduce the inhalation of harmful substances. When going out, it is recommended to give priority to masks marked with GB/T 32610-2016 standard.

Pay attention to wearing a mask correctly:

1. Ensure that the mask has a good fit with the face and does not leak.

2. It is suggested that the elderly, children and other special groups should choose masks with better comfort under the guidance of professionals or family members.

3. If the worn mask needs to be used again, it should be dried and put into a clean bag for collection.

4. Wear and replace the mask in strict accordance with the instructions for use.

Fifth, the correct use of air purification equipment is conducive to reducing the concentration of indoor PM2.5.

Interpretation: In heavily polluted weather, you should stay indoors as much as possible. When closing doors and windows, using air purification equipment is conducive to reducing the indoor PM2.5 concentration. Air purifier is a common air purification equipment. If conditions permit, especially in crowded places, we can consider installing new fans with high-efficiency filters.

When purchasing air purifiers, we should pay attention to selecting air purifiers that meet the national standards (GB/T 18801-2015 "Air Purifiers"), mainly referring to two types of indicators, namely, clean air volume (CADR) and cumulative purification volume (CCM). The applicable area of the purifier can be estimated by multiplying the particle CADR value by 0.1 (for example, the applicable area of an air purifier with a particle CADR of 300m3/h is about 30m2). The CCM value reflects the service life of the purification parts (the greater the CCM value, the longer the replacement or cleaning cycle of the purification parts).

Use the air purifier in strict accordance with the instruction manual, and pay special attention to:

1. The room should be closed as far as possible, and the periphery of the purifier should not be blocked, so as not to affect the air inlet and outlet.

2. First turn on the highest gear to purify the air quickly, and then use the silent gear to maintain the purification effect.

3. Open the window in time for indoor and outdoor air exchange.

4. The purification parts should be replaced or cleaned regularly according to the instruction manual.

6. Everyone should start from himself, save energy, care for the environment and reduce PM2.5 emissions.

Interpretation: Environment and health are closely related. Many diseases suffered by human beings are caused by environmental pollution, including air pollution. Protecting the environment means protecting human health. Reducing the harm of air pollution requires the joint efforts of the whole society. Everyone has the responsibility of caring for environmental sanitation and protecting the environment from pollution, and should actively cooperate with the state’s ecological environmental protection work and make contributions to preventing the harm of air pollution. Abide by the laws and regulations on environmental protection, abide by the social morality of paying attention to hygiene, consciously develop good habits of saving resources and not polluting the environment, and strive to create a clean, comfortable, quiet and beautiful environment. Advocate the use of public transportation, bicycles and other green modes of travel, prohibit indoor smoking, prohibit burning straw and garbage, reduce open-air barbecues and fireworks, adhere to a simple and moderate, green and low-carbon lifestyle, and oppose extravagance and waste and unreasonable consumption.

Treating heavily polluted weather scientifically and rationally and adhering to a healthy and civilized lifestyle are beneficial to physical and mental health. For more information about personal protection in heavily polluted weather, please consult the official websites of National Health and Wellness Commission, China Center for Disease Control and Prevention and China Health Education Center.

Online video VIP is nothing? The drama Joy of Life has to be filled with "VVIP"!

Beijing, Dec. 17 (Reporter Wu Tao) Joy of Life is being broadcasted, and besides the plot, there are also the practices of Tencent Video and iQiyi, two online video websites. After reading half, we have a "V in V", that is, VVIP, and started to pay for it. They have a nice name, called "VIP Pay-as-You-Go".

50 yuan watched 6 episodes in advance.

Recently, everyone in Joy of Life is watching it with enthusiasm. Tencent Video has launched a VIP pre-order service. On the basis of VIP watching 6 episodes first, VIP members can watch 6 episodes more when they update in 50 yuan.

The practice of iQiyi is similar, and 50 yuan, a VIP member, always watches 6 episodes. In addition, iQiyi also offers "Buy at will by episode", and pay 3 yuan for each episode in advance.

In fact, this is not the first time that Tencent Video has started the on-demand service. It seems to be their "standard action" to join on-demand in the phenomenal online drama.

In August this year, The Untamed’s video was broadcasted exclusively on Tencent. Near the finale, netizens were "shocked", not because of the plot, but because The Untamed initiated the on-demand practice and 30 yuan unlocked the finale of the last five episodes.

At that time, netizens who were chasing dramas were spending money to unlock the dramas while cursing them. This time, Joy of Life did the same thing again, and many users were annoyed: This operation is really obscene.

People’s Daily commented on this: VVIP is set up outside VIP, and extra money can be spent to enjoy advance on demand. Video websites are creating anxiety and inducing users’ consumption.

Netizens are angry.

This time, Joy of Life paid for VOD, and the netizens were really angry! Related Weibo rushed to the hot search, with tens of thousands of comments from netizens.

Some netizens said, "Please note that the advertisements are now full of feature films, and VIP has exclusive advertisements."

"This kind of behavior can’t be used to it. Like domestic violence, it is only 0 times and countless times."

"Before The Untamed earned a wave of blood, it was addictive to cut leeks."

There are also views that cinemas are also on-demand, paying for tickets, and everyone is happy to accept it. Why can’t video websites play online?

Immediately, a netizen said, "Joy of Life is in the middle of everyone’s reading, and we started to charge on demand without telling in advance. Have you ever seen a movie in the cinema that started to pop up after 30 minutes? "

Why do online video sites do this?

It is reported that Joy of Life’s resources have been leaked, so Tencent Video and Iqiyi did it.

The reporter noted that this statement was almost the same as that of The Untamed at that time. At that time, when The Untamed was popular, it was reported that Tencent Video had its own BUG and had to come up with the trick of on-demand video.

Compared with the leakage of resources, the pursuit of huge interests or the reasons for starting on-demand The number of buyers in Joy of Life is not known for the time being, because it is still being broadcasted in hot spots.

However, it was broadcasted in The Untamed at that time, and it was reported that within 2 hours, 753,000 users bought VOD. The Untamed charges 30 yuan for video-on-demand. In this way, Tencent’s video will exceed 22 million yuan in 2 hours just by the "action" of video-on-demand.

In the whole process of The Untamed VOD, Tencent’s video revenue exceeded 70 million yuan. In this regard, Tencent Video said, "No response".

Iqiyi also did not disclose the number of people on demand. As for the reasons why Joy of Life started VOD, as of press time, the reporter has not received a response from iQiyi.

The reporter noted that compared with The Untamed, Joy of Life’s on-demand charges have also increased, requiring 50 yuan to order 6 episodes in advance. Moreover, unlike The Untamed’s finale, Joy of Life started to play on demand, and the number of people on demand can be imagined.
