Take the first step and meet Lou Qinqin, secretary of jiangsu provincial party committee, the new weather, talking about "Su Daqiang" making up the short board and forging the long board.

  Xinhua News Agency, Nanjing, January 13 th, seeing things early and acting quickly, realizing "zero death" of COVID-19 patients and "zero infection" of medical staff; Break through the blockage and attack the difficulties, and play the role of "ballast stone" in a big economic province; Iron fist pollution control system governance, the best level of environmental quality innovation since the century … … In the extraordinary year of 2020, Jiangsu has withstood a major test in the Great War Exam, and generate has great kinetic energy.

  How does Jiangsu, the forerunner of a well-off society, start a new journey of modernization at the beginning of the 14 th Five-Year Plan? Implementing the spirit of the Central Economic Work Conference, how can Jiangsu make up the shortcomings and forge a long board to better serve the overall situation of the country? Xinhua News Agency recently interviewed Lou Qinqin, secretary of jiangsu provincial party committee and director of the Standing Committee of the Provincial People’s Congress.

  The GDP exceeds 10 trillion yuan, and the "high score" is handed over in the big exam.

  From building a new Jiangsu that is "strong, rich, beautiful and high" to "striving to be a model, striving to be a model and walking in the forefront", how can Jiangsu find the right position and "take the first step"?

  "The spirit of the instructions of the General Secretary of the Supreme Leader on a series of important speeches on Jiangsu’s work is consistent and in the same strain, and it also contains higher expectations and gives greater responsibilities." Lou Qinqin said that the essence of "struggle" lies in strength, and the original meaning of "walking" is running. Jiangsu will always follow the guiding direction, fully grasp the new tasks and requirements in the new development stage, creatively implement the central decision-making and deployment, and respond to risk challenges.

  A strong wind knows the grass. In the past year, under the strong leadership of the CPC Central Committee, Jiangsu struggled to win three tough battles: epidemic prevention and control, resumption of production and flood control. It is one of the provinces with the best epidemic control and the largest number of people rushing to help Hubei. The regional GDP is expected to exceed 10 trillion yuan, making positive contributions to China’s first recovery of positive growth among major economies in the world.

  How can Jiangsu turn "strong, rich and beautiful" freehand brushwork into exquisite and delicate "meticulous painting" and lay a solid foundation for opening a new journey of socialist modernization?

  "The central government has great trust, Jiangsu has a foundation, and the cadres dare to take responsibility and forge ahead." Lou Qinqin said, we fully realize that Jiangsu is an important ballast stone to stabilize the national economy, an important benchmark to promote high-quality development, and an important window to show the height of China. All work should be based on an international perspective, adhere to first-class standards, and show the feelings and responsibilities of "Su Daqiang".

  The potential of "strong" has been accelerated, and the per capita GDP ranks first in all provinces (regions) in the country. The scale of manufacturing industry, total industrial profits and the amount of actually used foreign capital are among the best in the country, and high-quality development has become the main theme.

  The quality of "wealth" is becoming more and more full, and the ratio of per capita disposable income of urban and rural residents is 2.25, which is one of the provinces with the smallest income gap between urban and rural areas in China. All the 2.549 million low-income people have been lifted out of poverty and the people’s quality of life has been continuously improved.

  The charm of "beauty" is becoming more and more noticeable. The accumulated retreat along the coastline is over 60 kilometers, and the ecological environment protection in the Yangtze River Economic Belt has undergone a turning point. The number of national ecological garden cities and ecological cities and counties ranks among the top in the country.

  The realm of "high" continues to climb, and the socialist core values are deeply rooted in the hearts of the people. The Jiangsu section of the Grand Canal Cultural Belt has become a model, and the number of civilized cities in the country ranks first in the country, and cultural self-confidence has been significantly enhanced.

  Stimulate the engine of innovation and polish the ecological background

  Adhere to the core position of innovation in the overall situation of modernization, and take self-reliance and self-improvement of science and technology as the support of development strategy. How can Jiangsu "see the new atmosphere"?

  "Jiangsu’s biggest resource is innovation resources, and its biggest advantage is the real economy. It must be a pioneer in science and technology and industrial innovation." Lou Qinqin introduced that Jiangsu has 167 universities and more than 850 scientific research institutions, and its regional innovation capability has been in the forefront of the country for many years. It has the largest manufacturing cluster in China, accounting for about one-seventh of the country’s output value.

  Strengthen the strategic scientific and technological strength, support Nanjing to establish a comprehensive national science center, support Zijinshan, Gusu and Taihu laboratories to establish national laboratories, and make a directional breakthrough in the "stuck neck" problem; Accelerate the reconstruction of industrial base and set about establishing necessary industrial backup systems; Strengthen the empowerment of digital technology and build an important hub node of global information network … … Jiangsu will comprehensively enhance the independent and controllable ability of the industrial chain supply chain, and make innovation and creation a rolling craze on the land of Jiangsu.

  The economy develops rapidly and has a large volume, but there are relatively many problems accumulated in the long-term high-speed development, and the "problems after development" are also encountered earlier. How can Jiangsu achieve ecological priority and green development?

  "We have inherited the solid foundation laid by our predecessors’ hard work, and we must also shoulder the historical responsibility of solving problems." Lou Qinqin said that Jiangsu unswervingly implements the new development concept and promotes structural adjustment, transformation and upgrading with great determination. It is not flustered by index fluctuations, disturbed by short-term changes, afraid of increasing difficulties, and confused by external discussions.

  During the "Thirteenth Five-Year Plan" period, Jiangsu’s energy consumption per unit GDP decreased by 20%. In the past three years, the number of chemical enterprises has decreased by more than 3,900, and the industrial output value has decreased by over 420 billion yuan.

  Over the past year, the State Council Jiangsu has promoted nearly 340,000 industrial enterprises and more than 2.4 million people to receive safety education. Last year, the number of accidents and deaths in the province decreased by more than 60%, and the annual economic growth is expected to be 3.5%, achieving coordinated development and safety.

  The green industrial belt along the Yangtze River reproduces the beautiful scenery of "the moonlight on the spring river", creates a desirable ecological scenery belt along the coast, and builds a high-grade cultural, ecological and tourism corridor along the Grand Canal … … Jiangsu system promotes the modernization of harmonious coexistence between man and nature, making "beautiful Jiangsu" more sensible.

  Serving the overall situation of the country, getting rich first drives getting rich later.

  Exploring the road for national development is the consistent requirement of the central government for Jiangsu. How does Jiangsu show its new responsibilities and new actions in serving the overall situation of the country?

  "Examine, plan and promote the development of Jiangsu in the national global coordinates, always keep a clear head, return to zero mentality, and be brave as a pathfinder." Lou Qinqin said that during the "14th Five-Year Plan" period, Jiangsu will actively expand domestic demand, and basically build "an industrial science and technology innovation center with global influence, an advanced manufacturing base with international competitiveness, and a two-way open hub with world cohesion", demonstrating Jiangsu’s role in serving the country to build a new development pattern, the Yangtze River Economic Belt, and the integration of the Yangtze River Delta.

  Incorporate into the national strategy and reshape the competitive advantage. Improve the development level and level of the Yangtze River urban agglomeration and the urban belt along the Grand Canal; Systematically plan the marine economy and create a "blue new growth pole"; Construction of tongzhou bay Yangtze River container transport new seaport and Xuzhou land port, Huai ‘an Airport and Lianyungang seaport "logistics golden triangle" … … Jiangsu will accelerate the change of the status quo of being strong in the south and weak in the north, strong in the river and weak in the sea, build a modern provincial development pattern, and build a domestic and international dual-cycle strategic channel.

  With the people’s longing for a better life changing from "whether there is" to "whether it is good", how can Jiangsu practice the development concept of "people-centered"?

  "The development that Jiangsu wants to achieve is to follow the new development concept, solve deep-seated problems, promote transformation and upgrading, and realize the development of phoenix nirvana." Lou Qinqin said that Jiangsu is constantly creating a high-quality life for the people, shouldering the responsibility of getting rich at first and then getting rich, and shouldering more burdens for the ultimate realization of common prosperity for the whole country.

  During the "Thirteenth Five-Year Plan" period, the standardization of basic public services in Jiangsu exceeded 90%, and the level of residents’ health, pension, child care, housing and sports was leading the country. Nearly 50 billion yuan was invested to implement more than 8,100 support and assistance projects, helping all 102 state-level poverty-stricken counties to get rid of poverty and nearly 4 million people to get rid of poverty.

  "Strive to make farmers and citizens no longer have obvious boundaries, so that there is no obvious gap in the quality of life between urban and rural areas, and realize the complementary symbiosis between livable cities and beautiful countryside." Lou Qinqin said that as a landmark project to implement the rural revitalization strategy, more than 200,000 rural houses in northern Jiangsu have been improved, and another 100,000 will be promoted this year.

  From "Spring to Shangtang" to "Kunshan Road", from proposing innovative development to promoting high-quality development, Jiangsu has always emancipated its mind and unified its thinking with new ideas, and promoted the vision pattern, thinking concept and working methods of cadres at all levels to fully adapt to the new requirements of the new era.

  "The 13 districts and cities in the province are 13 raiders who dare to fight hard. Together, they are a strong army that can win the battle, and jointly cast Jiangsu ‘ Big ’ , Jiangsu ‘ Strong ’ 。” Lou Qinqin said that Jiangsu will strive to be the first to make a successful case in the aspect of "no precedent", do better and faster in the aspect of "doing universally", accumulate pioneering experience in solving "common problems", and strive to write a new chapter in modernization of "being strong, rich and beautiful".

China is the country with the largest amount of marine plastics. How can plastic waste be discharged into ocean currents?

Several ways for plastic garbage to enter the ocean;

1. Dump directly into it. For some plastic wastes with no recycling value, in order to reduce the cost, they are either directly burned or dumped into rivers and finally merged into the ocean. This phenomenon is particularly common in rural areas of China, and at present, the treatment capacity of landfill sites in China is mostly saturated, and there is no matching treatment capacity with a large number of plastic wastes. In addition, some of them are daily garbage produced by human life, which are randomly discarded in rivers, beaches and the sea due to the incomplete recycling system and the lack of environmental awareness. The widespread use of disposable plastic packaging aggravates this situation, and the related garbage collection system may be underdeveloped or even non-existent.

2. Sewage outlet. Mainly discharged into rivers through sewage pipes of sewage treatment plants. The waste water of industrial products may contain plastic particles, and in some places where supervision is not strict, large pieces of plastic waste may be directly discharged with the waste water through the sewage outlet.

3. Secondary pollution caused by improper garbage disposal

(1) landfill leachate pollution caused by improper landfill. The plastic particles contained in these leachate will penetrate deep into the soil and pollute the groundwater. The groundwater and the water flow in inland lakes are complementary, and these polluted groundwater will enter the river through the lake and finally flow into the ocean.

(2) Non-standard treatment of plastic recycling family workshops in China. In these small workshops, it is often necessary to use a lot of clean water to clean plastic waste, and these plastic-washed wastewater will not be treated harmlessly, so it will directly carry a large number of plastic particles or even whole pieces of plastic into the river. Like these sewage, the remaining plastic garbage residues will be directly dumped on the river bed.

4. Maritime activities

Including marine aquaculture and fishing, exploration and development, all kinds of garbage and ship coatings discharged during the ship’s driving. Some large-scale maritime accidents, such as capsizing of ships and leakage of raw materials, will also lead to plastic waste entering the boundless sea.

What impact will plastic waste have on the ocean?

People call the plastic garbage floating on the ocean the "seventh continent" as a whole, and plastic pollution has become the "unbearable weight of life" for many marine creatures in the vast ocean.

The harm of plastics to wild animals is unimaginable to human beings.

Maybe you never thought that the plastic rope you threw away would sink into the sea and entangle with countless marine life. It is reported that at least 344 species have been caught in the pain of being entangled with plastic so far.Including all turtle species, more than two-thirds of seal species, one-third of whale species and one-quarter of seabirds.

The seemingly dazzling and exquisite packaging plastic paper is also "hidden" after flowing into the sea. Most marine life has eaten plastic fragments by mistake. According to the records of the media and related institutions,At least 233 marine species, including all turtle species, more than one-third of seal species, 59% of whale species, 59% of seabird species, 92 species of fish and 6 species of invertebrates, have ingested plastics..

In addition, touching or colliding with plastic products can also threaten the lives of marine animals. For example, fishing gear has been proved to cause wear and damage to coral reef ecosystem during collision.

The report "Marine Garbage: Understanding, Preventing and Mitigating the Adverse Effects on Marine and Coastal Biodiversity" issued by the Secretariat of the United Nations Convention on Biological Diversity collates the field investigation of polluted marine organisms since 2012. The report shows that plastic pollution has involved various marine biota such as fish, algae, marine birds, marine mammals and marine reptiles.

To make matters worse, plastics are encroaching on the habitats on which marine life depends at an alarming rate. UN Secretary-General Guterres pointed out that pollution, overfishing and the impact of climate change are seriously damaging the health of the oceans. He said that according to a recent study, by 2050, the total weight of plastic waste in the ocean may exceed that of fish.

Marine plastics are difficult to degrade.

Plastic is a synthetic macromolecular polymer, and its molecular structure is difficult to be destroyed by biodegradation. If plastic is to be completely degraded into small molecules, a large number of chemical bonds need to be completely broken. For polyethylene molecules, this requires a lot of energy. Therefore, it may take hundreds of years to completely degrade plastics. A BBC report mentioned that a plastic cup can "survive" on the earth for half a century, which shows that the degradation of plastics is very difficult. Unlike land, the refrigeration effect of seawater slows down the degradation process caused by sunlight and high temperature. Therefore, the process of comprehensive decomposition of marine plastic waste is more long and arduous.

-It is difficult to recycle marine plastics.

The vast majority of monomers used to make plastics, such as ethylene and propylene, come from fossil hydrocarbon maps. None of the commonly used plastics is biodegradable. Plastics will eventually accumulate in landfills or natural environments rather than decompose. The only way to permanently eliminate plastic waste is through destructive heat treatment, such as combustion or pyrolysis. Therefore, the near-permanent pollution of the natural environment with plastic waste is an increasingly serious problem. Plastic fragments have been found in all major ocean basins, and it is estimated that the plastic waste entering the marine environment in 2010 alone reached 4-12 million tons. Fresh water system and terrestrial ecological environment are increasingly eroded by plastics.

Nowadays, plastic waste is everywhere.

Sea water is flowing, and plastic will drift to all directions with the water flow; Seawater is also unfathomable, and plastics with different weights and qualities will be divided into different depths. No matter how hard people try, there is no guarantee that there will be no more plastic in the seawater of a certain area. When the plastic is turned into tiny particles, things become more complicated, the difficulty of recycling suddenly increases, and the harm is even greater. 

-There are limitations in monitoring marine plastics

1. There are disputes about the data model and sampling method of plastic waste.

A few days ago, a number of experts and scholars announced their monitoring results of microplastics off the coast of China at the APEC seminar on innovative ways to prevent and control marine debris. Although the monitoring scope is the same, their data results are quite different. Luo Yongming, a researcher from Yantai Coastal Zone Research Institute of Chinese Academy of Sciences, said that this is due to the differences in sampling tools and methodology.

Not only are there great differences in domestic research results, but the sampling and research methods of marine plastic waste have not been unified internationally. Li Daoji, a marine environmental expert, once pointed out that the international model research on the amount of marine plastic waste has not measured the amount of plastic waste discharged by various countries, and the research method is still open to question.

2. It is difficult to monitor and treat marine plastic waste.

It is very difficult to track the input and distribution of marine plastics, and there is a great difference between the annual input of plastics and the ocean and the estimated value of surface plastic accumulation. This difference is called the "missing plastic" problem. The monitoring of microplastics is even more difficult, because the particle size of microplastics is very small, and the analysis is very difficult. Therefore, the economic strength of different research teams, the ability to obtain data, the advanced analytical instruments and the feasibility of analytical technology will all have an impact on the monitoring results, which leads to great uncertainty in the monitoring of marine microplastics.

Therefore, it is unrealistic to try to clean up all the plastic garbage in the ocean by manpower. What human beings should do is how to reduce the production and use of plastics, improve the recycling and utilization rate of plastics, and control the source of pollution.

Tens of billions of years ago, the first single-celled life on the earth was born in the ocean, but there is no doubt that these white ghosts created by ourselves are slowly destroying the source of life. It is difficult for us to predict where the plastic bottles we throw away will float, just as we can’t predict what node these plastic wastes will bring to the fate of six billion human beings.

Give 100 thousand! Can undergraduates do scientific research well?

  At the beginning of August, Zhang Chenyang, a senior student in Tsinghua University, received a notice from the college that he would participate in the selection of the Young Students’ Basic Research Project (hereinafter referred to as the Young Students’ Project) of the Natural Science Foundation of China on August 22, and he could choose any topic as long as the basic research related to natural science was concerned, and the project cycle was one or two years.

  As the most important funding channel for basic research in China, the National Natural Science Foundation of China (hereinafter referred to as NSFC) brought undergraduates into its talent funding system for the first time, which attracted attention. In late August, the National Natural Science Foundation of China held the first evaluation meeting of young students’ projects in Beijing and Hefei. As a pilot, outstanding undergraduates from eight universities including Peking University, Tsinghua University and China University of Science and Technology (hereinafter referred to as China University of Science and Technology) were recommended to participate in the interview.

  China News Weekly learned that up to now, the evaluation and selection of this project has been completed, and those who pass the selection can get a research fund of 100,000 yuan. According to official website, the Intelligent Research Laboratory of the Chinese University of Science and Technology, an undergraduate student in the laboratory has received relevant funding. When the project was first announced, it once aroused doubts in the scientific community: Do undergraduates have enough ability to do scientific research?

  Who can get funding?

  Zhang Chenyang is an undergraduate of the first "Strong Foundation Program" in Tsinghua University, which was launched in 2020 to select students with excellent comprehensive quality or top-notch basic research. Shortly after entering school, Zhang Chenyang, with the encouragement of his tutor, tried to carry out a scientific research project in the field of ancient building restoration that he was interested in. He spent half a year researching and experimenting, and as the first author, published the research results of this project in the domestic core journal Journal of Geotechnical Engineering. This experience opened a new world for Zhang Chenyang. "This result made me very satisfied, and I began to feel that the process of doing scientific research and solving problems was very interesting, which was very different from learning in class."

  During his school years, he participated in many projects to support undergraduate scientific research, such as Tsinghua University’s "Academic Research Promotion Plan for College Students" and "Spark Plan", and the national training plan for college students’ innovation and entrepreneurship. In July, 2021, after the extreme rainstorm in Zhengzhou, Zhang Chenyang decided to turn to the research on flood forecasting and early warning. This is also the theme of Zhang Chenyang’s application in this young student project.

  Over the years, the Natural Science Foundation of China has built a funding chain for talent projects, including "excellent youth", "outstanding youth" and innovative research groups, but the funding targets are all scholars engaged in scientific research. Putting the talent funding port ahead is a new reform of the Natural Science Foundation of China this year.

  In May this year, the NSFC had a preliminary idea. In June, Dou Xiankang, Party Secretary and Director of the NSFC, led a team to Tsinghua, Peking University and other universities for investigation. In an exclusive interview with China Newsweek at the beginning of July, Dou Xiankang mentioned that during their investigation, they noticed that there are indeed some undergraduates who have spare capacity in learning and have interest and talent in scientific research. He has also seen some students who have completed their four-year courses in just one and a half years, thus having more time to do research. Judging from the law of talent growth, early discovery and targeted training of outstanding young talents will help them stand out as soon as possible and make great progress in the future, and also provide "flowing water" for building a high-quality basic research talent team.

  The speed of the project is beyond many people’s expectations. In July, the project for young students was formally established, and in August, the Natural Science Foundation of China organized a meeting review. "We completed all the evaluation work before the end of August, in order to complete the project establishment and funding in September, so that students can start the project at the beginning of the new semester and invest in the project research." Dou Xiankang said.

  Dou Xiankang said that at present, the project is still in the pilot stage, and the Natural Science Foundation of China hopes that the scope will be smaller, so the model of "recommendation+evaluation" will be adopted, and all students participating in the evaluation will be selected by universities according to relevant requirements. At the same time, however, in order to provide excellent students with opportunities for training and support, there is no quota limit for judging, and applicants with excellent performance can get financial aid. On August 22nd, Zhang Chenyang went to the office building of NSFC to participate in the selection. He noticed that there were about thirty or forty students from Tsinghua and Peking University.

  The selection of undergraduate programs is different from the projects of "Jieqing" and "Youqing" of the Natural Science Foundation of China. According to reports, in the evaluation of young students’ projects, students should show their projects within the specified 8 minutes and answer experts’ questions within the remaining 17 minutes. Dou Xiankang once mentioned to China Newsweek that there is no need for college students to present scientific research results like "Jie Qing", and the questions raised by some students may not be mature, but the judges can generally see whether the students have a solid scientific foundation and enthusiasm for science — — This is an essential quality for scientific research.

  Pan Xin, Dean of School of Aviation Science and Engineering, Beihang University, is one of the experts in the evaluation of young students’ projects. He condensed the criteria for judging students into one: whether students have the ability to ask questions. In the question-and-answer session, he will discuss with the students why he did this topic. The question is raised by himself or his tutor. "Perhaps most students have jointly raised questions after discussion with their tutors. After all, they are still young and have to attend classes. It is not easy to do this in a short time in a brand-new field."

  Pan Yi told China News Weekly that most of the students who participated in the evaluation were sophomores and juniors. He remembers that some students studied urban planning and management, used new tools to do big data analysis of regional economic heat, and evaluated regional economic vitality. "This is a social science topic, but it impressed me deeply. In the process of students’ migration from the field of partial management to the direction of mathematics and physics, new problems in cross-cutting fields were excavated." There is also a student who studies the stability of gravitational wave antenna device, hoping to solve the problems in the existing technology by designing new engineering and software.

  In addition, unlike the previous project review, the Natural Science Foundation of China suggested that the judges discuss with the students by means of communication rather than defense, "to inspire and guide them as much as possible and stimulate their interest in scientific research". When Pan Yi communicates with these children, he can feel that they all have a good theoretical foundation, but they also need more and wider academic exchange opportunities.

  When Zhang Chenyang applied for related scientific research projects before, he was mostly asked about the professional knowledge of the project, and the tutors in the school mostly communicated with him about the details of the plan. At the review site, seven or eight experts from the audience raised about 10 questions, including basic knowledge, research experience, scientific research plan, etc., and some teachers gave him suggestions on research ideas. "I want to study the early warning of mountain torrents in North China, and then spread the experience to the whole country. A teacher at the scene suggested that I can do experiments nationwide first, and then sum up good methods. This and my research are two kinds of ideas, which can give me some inspiration. "

  In addition, we need to pay attention to how to select students who are really interested in scientific research, so that the young student project will not become the "hat" of undergraduates. According to Mu Rongping, a researcher at the Institute of Science and Technology Strategy Consulting of China Academy of Sciences, some talent funding projects have become "hats", which has nothing to do with the funding itself. The problem is that subsequent employers regard these funding as a precondition for talent admission or evaluation. Funding outstanding undergraduates to do scientific research may not be a prerequisite for sending graduate students, which may be helpful to the selection of talents for young students’ programs.

  Can undergraduates do scientific research well?

  In the evaluation team that Pan Yi participated in, the projects declared by 11 students were very difficult, "it is difficult to make a complete solution in a short time", but Pan Yi did not expect these students to publish several papers or patents two years later, or to push the research problems to a new height. In his view, the real value of the young student project lies in that students can receive the training of scientific research paradigm and be more firmly involved in scientific research in the future. Mu Rongping pointed out to China Newsweek that the establishment of this project by the Natural Science Foundation is also in line with the laws of scientific research. Students need to participate in basic research, attend more academic conferences, communicate with outstanding peers at close range, and improve their thinking ability in solving scientific problems.

  According to reports, on August 21st, the day before the evaluation of young students’ projects, NSFC invited Pan Jianwei, an academician of China Academy of Sciences, Luo Yi, executive director of the Department of Chemistry and Physics of Chinese University of Science and Technology, and other scientists to give academic reports to the undergraduates who participated in the evaluation. Dou Xiankang said, "In the future, we will provide them with more opportunities to participate in comprehensive high-end scientists’ forums, hoping to inspire and guide them to embark on the road of scientific research by letting top scholars at home and abroad communicate face to face with outstanding undergraduates, making reports, talking about experiences and feelings."

  Mu Rongping told China Newsweek that, according to the laws of scientific research, different disciplines are different, and many scientists at home and abroad have made outstanding achievements at a young age in basic theoretical disciplines such as mathematics and physics. At present, the young students’ program is still in the pilot stage, with a small number of students selected and a low amount of funding, which may not be as much as a large project of the Natural Science Foundation of China. It is a good attempt to select students who are really interested in scientific research, and the outside world can give more tolerance.

  Pan Xin has more than ten years of teaching experience, and is also responsible for the teaching reform planning and scientific research development of the college. In his view, the young student program is a "flag" and signal, that is, the state attaches importance to the coordinated development of education, science and technology, and talents, which can guide more university administrators to think about talent training at the undergraduate level.

  Pan Yi pointed out to China Newsweek that most of the courses at the undergraduate and postgraduate levels in domestic universities are imparting known knowledge. There are fixed class hours in one semester, and what to talk about in each class will be planned in advance, eventually teaching students a set of systematic knowledge. Only when students really enter a research topic can they begin to transition to exploring the unknown. He hopes that this process can be advanced.

  As early as 2005, the famous "Qian Xuesen’s question" was put forward. Today, how to cultivate top-notch innovative talents is still a common challenge for China University. Pan Yi noticed that some undergraduates, even postgraduates, lack scientific research training, and it is difficult to write a paper that people can understand. In his view, China’s basic education, undergraduate courses and practical equipment in some universities are not bad, but in the postgraduate stage, there will be a clear gap between China and top foreign universities. In top foreign universities, most natural science courses are required to write papers or reports at the end of the class. Students need to think, investigate and explore the unknown on the basis of the classroom knowledge system, but most courses in domestic universities still test the known content.

  Mu Rongping believes that what is more important behind the young students’ project is how colleges and universities can reverse the learning and thinking habits of undergraduates, and turn from memorizing answers to discovering and exploring problems. "The key to real scientific research is to see who can find the real problems".

  Lu Xiaodong, a researcher at Peking University Institute of Education, has been paying attention to undergraduate research for many years. In his view, NSFC’s funding for undergraduates is not new, but there is a new funding channel. Over the past 20 years, many universities in China have been supporting undergraduates who have the ability to learn to participate in scientific research. The traditional impression that "doctor is the entry stage of scientific research" is actually a cognitive misunderstanding.

  Take Peking University as an example. In 1998, Li Zhengdao set up a "political fund" to introduce the scientific research model of American research universities into China. Subsequently, Peking University established a set of management system with "research courses" as the core, and incorporated undergraduate scientific research into the regular curriculum. Relevant subsidies included "political fund", "president fund" and "Mao Yugang fund". According to the "research course" of Peking University, the applicants should be sophomores, and their GPA should rank in the top 30% of the college. At the same time, the standardized management of the course requires students to ensure that they invest enough time, and there are requirements for the mid-term and completion of the project.

  Pan Wei introduced that since 2021, Beihang University has conducted pilot research classes for sophomores and juniors. Each pilot college will open a research class as an elective course, accounting for 2 credits, and requires key laboratories at or above the provincial level to invest certain experimental conditions to support students. Pan Yi mentioned that compared with the traditional classroom, the scientific research classroom is open, and students may be faced with the most cutting-edge science and technology in a certain field. They can do experiments, research or theoretical formula derivation. There is no standard answer to this process. The most important thing for students is to learn scientific research paradigm, cultivate the ability of literature research, independently design operable experiments and write experimental reports.

  "We have been piloting for 3 years, and about 90% of the undergraduates of Beihang University have taken scientific research classes. I obviously feel that after the preliminary training, the level of graduation design has been significantly improved." Pan Yi told China Newsweek. Lu Xiaodong once met some undergraduates who quit halfway because of lack of interest when doing scientific research projects. There are also some students who have participated in short-term laboratory projects in different disciplines. Many teachers have found that these students are seriously involved in each project, and they gradually clarify the future research direction in the process, even if they do not produce visible research results, they are also very valuable.

  Compared with China, foreign top research universities began to encourage undergraduates to do research earlier. As early as 2000, Lu Xiaodong went to the United States to inspect the management of first-class universities, focusing on undergraduate education at the University of California, Berkeley. As a research university, Berkeley attaches great importance to undergraduate scientific research, and even regards it as an important part of undergraduate education. Since the 1990s, the university has set up special funds to support undergraduates to do scientific research. In 1997, it set up an undergraduate research office to organize and serve students’ research. Besides providing some information about project application, it will also help students understand what research is, how to write project applications and draw up reports through lectures. In addition, Harvard University, Massachusetts Institute of Technology, California Institute of Technology and many other American research universities have set up relevant institutions and projects to support undergraduates to do scientific research.

  The undergraduate stage is a critical period for the cultivation of academic aspirations. Lu Xiaodong noticed that many alumni of Peking University who have made their mark in academia or returned to school as teachers have participated in research courses at the undergraduate level if they look at their resumes. In 2023, Zhang Cheng, a professor at Fudan University School of Management, and others published an article "The Impact of Undergraduate Research Projects on Personal Research Career Development — — In a retrospective cohort study, the research career development of undergraduate students and graduates of Fudan University from 2000 to 2017 was investigated, and the final sample included 576 data. It is found that compared with students who have not participated in scientific research projects, the probability of undergraduates who have participated in related projects graduating from doctoral programs has increased by 14.1%, and the probability of choosing scientific research positions in formal jobs has also increased by 17.2%.

  The article points out that the important reason is that early scientific research training promotes students’ understanding of scientific research and cultivates students’ self-confidence in this field. Zhang Cheng and others believe that the key is not simply to let students take part in teachers’ topics or simply to pursue the publication of articles, but how teachers guide students to complete scientific research tasks, achieve goals and constantly build confidence in this process.

  Relevant research points out that domestic undergraduate research projects have been carried out for many years, but the overall start is late, the coverage is narrow, the implementation effect of different universities is uneven, and relevant policies still need to be improved. Lu Xiaodong observed that in the past years, some university administrators have also visited Peking University to investigate their experience. In his view, the most important thing is that school administrators and teachers should first change the concept that gradual learning at the undergraduate level and problem-centered learning triggered by undergraduate research do not conflict, but will promote each other. To support undergraduates in scientific research, colleges and universities should first straighten out this problem. Secondly, relevant experts believe that the integration of undergraduate scientific research into the formal curriculum will help reduce the conflict between students’ participation in scientific research and course learning.

  In addition, experts say that domestic universities need to invest more resources in undergraduate research. In China, except for some top universities, most of the undergraduate research work is assigned to the Academic Affairs Office. The relevant teachers lack enough energy and time to organize undergraduate research, and some teachers lack understanding of undergraduate research training, so it is difficult to undertake detailed guidance. At the University of California, Berkeley, in order to support teachers to participate in students’ scientific research, teachers will receive project assistance and a small grant of $ 300~600 to partially pay for students’ research-related expenses.

  How to motivate teachers to actively participate is very important. In Lu Xiaodong’s view, taking undergraduates to do research really requires teachers to invest more energy. Some colleges and universities can give priority to selecting some willing excellent teachers. Teachers should also think clearly about the value and significance of this matter. Undergraduate scientific research courses can play a real role in the process of cultivating top-notch innovative talents, but it is not achieved overnight.

  Magazine title: Natural Science Foundation of China subsidizes undergraduates for the first time.

Strengthening the background of big factories, Pentium Pony Long Life Edition is listed.

Golden car reward

On October 28th, 2025 long-life versions were listed in Hangzhou, among which the 222km long-life versions of Smart Horse and Lightning Horse were priced at 36,900 yuan and 39,900 yuan respectively.

In terms of product strength, the motor power of Xiaoma’s long battery life version reaches 30kW, which is 10kW more than the current model. In addition, the new car is equipped with APP remote car control function, which can open the air conditioner with one button and unlock the door. The fast charging function can increase the battery life by 100km after charging for one hour.

With the blessing of configuration, the starting price of Pentium Pony Long Life Edition is 36,900 yuan, which is more competitive than its competitors, Geely Panda and Hongguang MINIEV. However, the Pentium pony is still not confident enough. At the press conference, the Pentium pony has been emphasizing that it is a "FAW Pentium" model.

First of all, the self-confidence of Pentium Pony comes from the brand level. Compared with Geely Automobile and Automobile, which are independent head enterprises, and SAIC-GM-Wuling, which has been deeply involved in the field of micro-electric vehicles for a long time, the popularity and brand influence of Pentium brand are much smaller.

Secondly, in terms of vehicle-building strength, users are most worried about safety and quality for micro-electric vehicles. However, in order to achieve a higher safety factor, micro-electric vehicles also have high requirements for vehicle-building technology, and Pentium Pony is the first micro-electric vehicle of Pentium.

Therefore, with the endorsement of China FAW, a central enterprise, and the 70-year history of FAW Group, Pentium Automobile hopes to convince users of its own car-making strength and quality. Before the launch of the new car, Pentium also invited bloggers from online celebrity to visit and introduce the production technology of its Yancheng factory.

At the listing conference, Pentium also introduced the production and manufacturing of Yancheng factory at length. For example, Yancheng Factory adopts millions of UFC inspection tools, and the stamping parts are 100% inspected. The Pentium pony has gone through 1.26 million kilometers of road test, and the torsional stiffness of the car body has reached 14,370 m/.

Pentium brand has high hopes for Pentium pony because it bears the heavy responsibility of sales. According to the plan, the sales target of FAW Group’s own brands must reach 900,000 this year, and the sales of new energy vehicles must reach 500,000. This important task is mainly completed by Hongqi brand and Pentium brand.

From January to September, the cumulative sales volume of Pentium cars was 98,516 vehicles, up 19% year-on-year, among which the cumulative sales volume of new energy was 44,318 vehicles, up 113% year-on-year. At present, Pentium pony is the backbone of Pentium brand sales, with sales reaching 9615 vehicles in September, three times more than another new energy vehicle, Pentium NAT, and accounting for half of the total sales of Pentium brand.

But over-reliance on Pentium pony is not a good thing for Pentium brand. FAW Group has always had the goal of becoming a bigger and stronger independent brand. In May, 2021, at the brand-new strategy conference of the 15th anniversary of FAW Pentium, Pentium Automobile released a brand-new LOGO and brand positioning as "the middle and high-end brand in the mainstream automobile market in China".

Facing the "14th Five-Year Plan", FAW-Pentium set the ambition of achieving 300,000 vehicles in 2023, 600,000 vehicles in 2025 and challenging 1 million vehicles. However, in 2023, Pentium sold only 120,000 vehicles, and this year’s sales pressure is not small.

In terms of product planning, from 2023 to 2025, Pentium will complete the layout of five new energy products and eight traditional energy products at the speed of launching more than two new models every year, which will cover the mainstream passenger car market from A00 to B. However, the sales of Pentium T90 and Pentium NAT, which were launched in 2023, were not satisfactory.

For the current Pentium car, there is both sales pressure and the hidden worry of brand image decline. At present, other models of the Pentium brand are difficult to take on, but if the sales volume depends heavily on low-end micro-electric vehicles, it is not conducive to building a mid-to high-end brand positioning. According to the market demand, grinding out more explosion models with medium and high prices has become the direction that Pentium needs to focus on in the future.

Chengdu 42-year-old hot mom achieves marathon grand slam dream (photos)

  Huaxi Dushi Bao reporter Luo Qin photography Chen Yuxiao

  42.195 kilometers, this is the whole distance of a marathon. Do you have the courage to challenge? Many people don’t know that in Chengdu, a woman who is over 40 and is the mother of two children has achieved the World Marathon Grand Slam — — Dream of the world’s top marathon tour.

  Her name is Ding Yan. From September 27th, 2015 to April 24th, 2016, she participated in Chicago Marathon, New York Marathon, Tokyo International Marathon, Boston International Marathon and London International Marathon.

  On May 29th, 2016, Ding Yan won the six-star medal of "World Marathon Grand Slam" in Jeju Island, making her the third woman in China and the first woman in Sichuan to finish the World Marathon Grand Slam.

  On August 8, in a cafe in Chengdu, Ding Yan, smiling, accepted an interview with a reporter from Huaxi Dushi Bao. The topic of the day actually started from the parent-child movement.

  attempt

  In order to make her son love sports, she led the whole family to ride and taste the sweetness.

  8 at 10 am, Chu Qing after the rain. Ding Yan, dressed in a black dress, sits in a corner of a cafe in Shuangnan, Chengdu. She carries with her a few thick albums, which are full of stories and experiences about her family’s cycling trips and her marathon at home and abroad for many years.

  "Actually, my contact with running and marathon was very accidental. It can be said that it was for my son at first." As soon as she sat down, Ding Yan opened the chatterbox. Although we met for the second time, this cheerful, warm and generous woman was not unfamiliar and restrained when chatting. She even opened the snacks with her and put them on the plate on the table.

  Born in 1974, Ding Yan worked in engineering budget. Because she was busy with her husband’s career, her son was always given to her grandmother when she was born. Because of her busy work, it is difficult for her to accompany her children often, and she always feels guilty in her heart.

  In 2012, Ding Yan and her husband’s career had already been on the right track. When she saw her son who was only a junior but was over 1.7 meters tall, she figured that it would be better to take her son to participate in parent-child sports, which would not only exercise, but also temper the will of the doll. Mother and son could also exchange emotions and enhance understanding.

  In that summer vacation, Ding Yan took her son to join the parent-child cycling team organized by friends. A group of more than 20 people are parents with dolls. Everyone started from Beijing and rode all the way to Yantai, Shandong, covering more than 900 kilometers and taking more than 10 days.

  "In the first day or two, the doll complained bitterly and had a heavy negative mood," Ding Yan recalled, but seeing other children of the same age or younger in the team riding with heavy loads, his son’s competitiveness was aroused, and in the following days, he gradually found the feeling, and the more he rode, the more interested he became. Finally, the group arrived at their destination safely and smoothly.

  In this way, Ding Yan and her son fell in love with cycling. In the Spring Festival of 2013, mother and son and their riders went cycling in Sri Lanka. In the Spring Festival of 2014, Ding Yan’s son and the same group of riders went to Sri Lanka again. "Dolls who fall in love with sports have different spirits." Ding Yan said that his son has changed a lot, his body is stronger, and he is more generous with strangers.

  It’s not just her son who changed. Ding Yan also fell in love with sports in this process, and gradually tasted the sweetness — — She found herself in good shape and lost weight, and all her friends thought she was much younger.

  In the summer vacation of 2014, Ding Yan took her husband and son to the UK. After a 21-day cycling, she felt that cycling could no longer satisfy her. "We should find a sport that can be adhered to for a long time and make sports a habit."

  fascinated

  It is a pleasure for her to fall in love with running marathon in her late 40 s

  Under the introduction of a friend, Ding Yan joined a running friend group in Chengdu. Every Monday, Wednesday and Friday, she will meet with her running friends in Jincheng Lake and run in the night.

  Through the running friends team, Ding Yan met Ha Ge, a well-known outdoor sports enthusiast in Chengdu. This opened a new door for her who became a monk halfway and fell in love with running when she was nearly 40 years old.

  "At that time, I realized that running requires professional knowledge, and I also learned about marathon running for the first time." In Ding Yan’s view, the marathon is a professional athlete’s business, and she never thought that she could participate. Under the "fudge" of Hage, she learned that the threshold of marathon is not high, and she only needs to persist in training to have opportunities, and signing up for marathon can also make her usual running training more motivated.

  On November 9, 2014, the Xichang Marathon Half Race was Ding Yan’s first marathon. It took less than two months from registration to competition, but with the encouragement of runners, Ding Yan, who can usually run for 12 kilometers without stopping, successfully completed the half-horse. On November 29th, Ding Yan participated in the Chengdu Xinchuan Cup Half Marathon Charity Run. In January 2015, Ding Yan ushered in the first all-horse in her life — — Xiamen International Marathon finished in 4 hours and 19 minutes.

  Japan Kyoto Marathon, Hong Kong Lantau Cross Country Race, Chongqing International Marathon, Dujiangyan Double Heritage Marathon, Beijing International Marathon, Sweden Gothenburg Half Marathon and Singapore Sunset Marathon. From March to July, 2015, Ding Yan participated in and completed the above events in less than half a year. She fell in love with the marathon like a demon. In the eyes of ordinary people, the marathon is very boring and tests endurance and perseverance. In her eyes, every second is enjoyment.

  challenge

  Test the Water Berlin Marathon and Start the Six Grand Slam Marathon Tour.

  The more you run, the more you love it. The more you run, the more obsessed you are. Ding Yan’s love for marathon has gradually become fanatical. Through the introduction of runners, she came up with the idea of challenging the world’s top marathons, and with the help of professional organizations, she signed up for the Berlin Marathon in Germany and started the six Grand Slam marathons in the world.

  On September 27th, 2015, just seven days after running the Beijing International Marathon, Ding Yan stood behind the Brandenburg Gate, the starting point of the Berlin Marathon. With the cheers and cheers of people on both sides of the track, she took a step and began to run rhythmically. She ran well in the first half, but when she reached 23 kilometers, she felt more and more laborious, her pace became heavy and her speed became slower and slower.

  In this way, when she struggled to run for about 28 kilometers, an old woman with silver hair and a cross-country water bag appeared in front of her. "The old man’s pace is even and his breathing is very rhythmic. Driven by her, I adjusted my breathing rhythm and started running again." Ding Yan said that on the way, she communicated with her grandmother in simple English. I learned that this old man named Georgie Hamilton is from London, England, and her daughter lives in Berlin. Her job is to coach the European celebrity swimming competition.

  Running 38 kilometers away, just beside the hotel, Ding Yan kept searching among the audience on the roadside, hoping that her relatives would appear in front of her. There seems to be telepathy, and she soon saw her little daughter and her family Xiaomei in the crowd. She stopped to approach her daughter, and the mother and daughter gave a deep hug. The 4-year-old daughter was so excited that she held her mother and refused to let go.

  "I really want to run the whole course with my daughter, but there are still more than 4 kilometers to reach the finish line. I really have no physical strength." Ding Yan reluctantly gave her daughter to her family, continued to return to the team, and rushed to the finish line, and finally completed the first show of the six Grand Slam marathons in 4 hours, 29 minutes and 01 seconds.

  achievement

  The British old lady who finished six Grand Slams became her inspirational role model.

  On October 11, 2015, the Chicago Marathon was held in the United States. With the cheers of enthusiastic people along the way, Ding Yan successfully ran through the finish line, and the result was fixed at 4 hours, 35 minutes and 24 seconds. On November 1st, she completed the New York Marathon in 4 hours, 34 minutes and 20 seconds.

  In February 2016, Ding Yan ushered in the fourth stop of her Grand Slam — — Tokyo International Marathon, Japan. She made up her mind that she couldn’t leave her regret because of injury. It was also at this stop that she set the goal of running the world’s six Grand Slam marathons within one year.

  Because there were many broken roads near the finish line, she had to walk and run, and when the finish line appeared in front of her, she couldn’t help but wet her eyes with tears.

  On April 18th and 24th, 2016, Ding Yan completed the Boston International Marathon and the London International Marathon, respectively, and completed her dream of running the six Grand Slam marathons in the world. It is worth mentioning that in London, she reunited with the old British lady Georgie Hamilton. This old man who still loves sports has become Ding Yan’s idol and role model.

  has some knowledge of

  World Marathon Grand Slam

  There are four Grand Slams in tennis and six Grand Slams in marathon. The World Marathon Grand Slam is the world’s top marathon tour. It was established in 2006, including the five most influential marathons in the world, including London, Berlin and Boston, Chicago and new york. Since 2013, the Tokyo Marathon has been added.

  thoughts expressed in words

  Won the "Grand Slam" six-star medal.

  The marathon will not stop.

  On May 29th, 2016, in Jeju Island, South Korea, Ding Yan received her own "World Marathon Grand Slam" six-star medal. It is understood that only runners who have completed the "World Marathon Grand Slam" can get this six-star medal by applying to the World Marathon Grand Slam organization and verifying it. On the same day, Ding Yan’s husband and children in China were not idle. They participated in the parent-child run in Chengdu Jincheng Lake, and their daughter also showed her father how to warm up before running. She said that these were all learned while running with her mother.

  Nowadays, Ding Yan’s life is inseparable from running. She took her family to love sports and enriched her life. She said with a smile that she was busy with her career, and she was very insecure when she got fat. She even avoided taking pictures. Later, she fell in love with running, and her body was healthy. People were more sunny and cheerful, and so were children. She loved sports at an early age. My 5-year-old daughter, my 16-year-old son and her busy husband will follow her to exercise and run whenever they have time.

  "My marathon trip will not stop. I have planned the Chicago Marathon in October this year and the Hawaii Marathon in December. Achievements are not important. Thanks to sports, I am closer to my family and my life is richer and more fun. " Speaking of her fate with the marathon, Ding Yan is still unfinished.

Mazda is completely mad, let’s see which one is worth starting.

Who is more in line with the needs of consumers, new energy vehicles or fuel vehicles, depends on local conditions and people. What I want to introduce to you today is. As for the outstanding performance of the car, please read it together.

First of all, from the appearance, the front face of Mazda 3 Angkor Serra looks very individual, and with the three-piece air intake grille, it looks very fashionable and generous. Coupled with dynamic and lively headlights, it has improved a certain level. The car is equipped with LED daytime running lights, automatic opening and closing, adaptive far and near light, delayed closing and so on.

AITO asked about the release of the new M7 series, which was delivered for sale at a price of 249,800-329,800 yuan.

Beijing, China Broadcasting Network, September 13 th On September 12 th, the new M7 series of AITO was officially listed. As a luxury medium-sized SUV with great wisdom, large space and super safety, the new M7 will bring consumers a brand-new travel experience. At the press conference, Yu Chengdong, managing director of Huawei, CEO of BG and CEO of BU, a smart car solution, said: "We have invested 500 million yuan in the new M7 series of AITO, and used solid materials and the best technology to make it not only an intelligent cockpit ceiling, but also an intelligent driving ceiling and an intelligent safety ceiling! In the invisible and visible places, it brings users the ultimate experience that is more advanced than far ahead! "

"Shuangzhi" continues to be far ahead, and the whole country can drive with wisdom.

The new M7 in Wenjie is equipped with HUAWEIADS2.0 advanced intelligent driving system [the related functions of Huawei ADS 2.0 advanced intelligent driving system are unique to the new M7 series Max intelligent driving version in Wenjie], which is the first to realize high-speed and urban advanced intelligent driving independent of high-precision maps. It is estimated that in December this year, the urban intelligent driving pilot assistance (urban NCA) [planned to be supported by Q4 in 2023, and driving on structured roads with clear road boundaries] will realize the intelligent driving experience that can be driven all over the country. Since its release in April 2023, HUAWEIADS2.0 has built a rich scene library on the AI ? ? training cluster, learning 10 million +km in depth every day, and continuously optimizing the iterative intelligent driving algorithm and scene strategy. As of September, 2023, the long-distance NCA pilot MPI (average takeover mileage) is as high as 200km, and the success rate of urban elevated import and export is as high as 99%+, which is comparable to that of "old drivers".

Behind the excellent intelligent driving experience, the new M7 in Wenjie is equipped with 27 sensing hardware such as an overhead lidar, three millimeter-wave radars, 11 high-definition visual sensing cameras and 12 ultrasonic radars, and cooperates with the high-performance computing platform and Huawei’s self-developed anthropomorphic algorithm. Realizing the dynamic and static targets (including GAEB (Automatic Emergency Braking of Alien Obstacle) is called God (General Obstacle Detection). HUAWEIADS supports the identification and emergency braking of alien obstacles of a certain size outside the white list of pedestrians, cars and cyclists at a certain speed. The active safety function only plays an auxiliary role and cannot replace the driver’s control. The driver should always maintain the necessary duty of care and intervene in time according to the surrounding environment. Among them, HUAWEIADS2.0 upgrades the God (Generic Obstacle Detection Network) 2.0 network pioneered by the industry on the basis of integrating BEV (Bird’s Eye View) perception ability, which can identify alien objects outside the white list of general obstacles, finely identify the types of obstacles (such as distinguishing ambulances, police cars, etc.), and the recognition rate is as high as 99.9% [Some functions need OTA upgrade support, please use the actual situation. RCR2.0(RoadCognition&Reasoning (Road Topology Reasoning Network) can match the navigation map with the real world, which can not only "understand things" but also "understand the road". In addition, based on the multi-sensor fusion perception ability, the new M7 in Wenjie also has the intelligent parking ability of visible parking, and supports parking in parking service and ultra-narrow parking spaces in the park.

HarmonyOS’s smart cockpit is smoother and more fun. The super desktop brings more mobile phone applications, and the "touch" of the mobile phone can realize the flow of applications such as drama and games. Mobile phone aerial photography can also be transferred to the cockpit screen, allowing the whole family to "sit around the world" in the car. Xiaoyi Smart Voice can navigate offline even when the signal is not good, and it can also realize convenient experiences such as voice-controlled photo sharing at any time and payment without getting off the bus. In the back row, HUAWEIMagLinkTM develops a new way to play space scenes. Huawei tablets can be linked immediately, realizing multi-device linkage, and the intelligent cockpit can be changed into a personal workshop, a multi-person meeting room and a children’s study, and the magic space can be flexibly switched to create "mobile whole house intelligence".

All-round rejuvenation and upgrading, the super-large space is unparalleled.

The new M7 fully considers the needs of family travel. The top five seats have the leading effective space in the car at the same level, with a length of 3338mm, and each seat is very spacious. The trunk is 1100mm deep, with a standard volume of 686L, and can easily accommodate 12 20-inch boarding boxes [the measurement method conforms to GB/T19514-2004/ISO3832]. After the second row of seats are laid down and connected with the trunk, the maximum depth is extended to 2051mm, which can form a loading space of 1619L [trunk volume measurement method conforms to GB/T19514-2004/ISO3832, only applicable to five-seat version], which can easily accommodate 30 20-inch suitcases, and can switch various modes such as a 2-meter big bed, so that it is easy to lie flat for two people and cooperate with the 52L storage compartment of the trunk.

The new M7 enjoys a more flexible layout with six seats, giving users more choices. The overall space of the front, middle and rear three rows reaches 2605mm, and both the six-seat and four-seat modes have spacious interior space. The whole car is full of seats, and there is still a 1.1-meter trunk. The standard volume of 188L can hold four 20-inch suitcases. After putting down the rear seat, it can be expanded to 775L, which can accommodate four 28-inch suitcases at the same time, easily meeting the needs of multi-scene vehicles.

Active and passive double insurance, double super safety and more reliable.

Passive safety is not afraid of accidents, active safety avoids accidents, physical safety and intelligent safety are double insurance, which makes the new M7 series double super safety in the world. In terms of passive safety, it is safer and more reliable to ask the new M7 body structure to match the mold opening and rebuild the welding production line. The submarine-grade thermoformed steel accounts for 24.4% of the whole vehicle (thermoformed steel refers to steel with tensile strength ≧1300MPa). 24.4% is the total weight of hot-formed steel/weight of body-in-white frame (excluding opening and closing parts). Hot-formed steel refers to steel with tensile strength ≧1300MPa. 24.4% is the total weight of thermoformed steel/weight of body-in-white frame (excluding opening and closing parts)], and high-strength steel and aluminum alloy account for 80.6% [High-strength steel covers high-strength steel, advanced high-strength steel, ultra-high-strength steel, thermoformed steel and other steel grades; The tensile strength is 300 MPa-2000 MPa; 80.6% is the total weight of high-strength steel and aluminum alloy/the weight of body-in-white frame (excluding opening and closing parts), which is better than the mainstream models of 500,000 luxury brands. At the same time, CBS (Composite Bodies Solutions) is introduced [CBS (Composite Bodies Solutions) is a structural strengthening technology of mixed materials, which can not only improve the rigidity of the car body without excessively increasing the mass, but also improve the NVH performance of the whole car], thus effectively improving the rigidity and collision safety of the car body]. In addition, the new car comes standard with eight airbags and front double pre-tensioned seat belts.Based on more real scene verification, it provides users with all-round driving safety guarantee.

In terms of active safety, the new M7 is not afraid of things and can avoid them. The active safety capability of HUAWEIADS2.0 continues to evolve, and the omni-directional anti-collision system is launched to realize the forward, lateral and backward omni-directional anti-collision capability, and the omni-directional protection is the real safety. The maximum braking speed of AEB(AutomaticEmergencyBraking) is increased to 90km/h (the data comes from the evaluation of third-party media), which can reduce 90% (this is the predicted value based on statistical data) traffic accidents caused by inattention and complex road conditions, and the active safety capability continues to lead in the industry.

The cart is comfortable and easy to drive, and the whole family is comfortable to travel.

The new M7 focuses on family travel scenes and comprehensively optimizes the driving experience. The big five seats come standard with brand-new "cotton candy" seats, with 10 layers of comfortable laminated design and a total foam thickness of 100mm;; The ventilation, heating and massage functions of four seats are standard, and each seat is as comfortable as first class. Through the Xiaoyi Wisdom Assistant, the double-row nap function of the main driver and the auxiliary driver can be turned on by voice. Enjoy six new zero-gravity seats, so that users can unload their fatigue when riding, as if they were in a space capsule, bringing the ultimate comfort and relaxation experience. In addition, the new M7 is equipped with front and rear double air-conditioning boxes, 17 air-conditioning outlets, rear air-conditioning touch screen, fully automatic electric pedal [electric pedal is optional] and other leading and comfortable configurations. A healthier "zero formaldehyde" cockpit allows the whole family to enjoy a healthy and comfortable travel experience at any time.

In terms of driving and control experience, the new M7 upgraded Huawei Datstm2.0 (Dynamic Adaptive Torque System) and front and rear suspension double FSD(FrequencySelectiveDamping) variable damping shock absorbers to make driving more stable and smooth. The new M7 in Wenjie is equipped with HUAWEIDriveONE extended-range electric drive platform, and the four-wheel drive version accelerates by 4.8s(4.8s is the measured value of the four-wheel drive version’s 100km acceleration), leading in power performance at the same level. Under the condition of full oil and full electric CLTC, the new M7 has a comprehensive cruising range of 1300km(1300km is the total cruising range of the rear-drive version with full oil and full electric CLTC; The actual cruising range of the vehicle is different in actual road driving, which is influenced by different environmental temperatures, road conditions, driving habits and operation, battery life and other objective factors). The battery has a pure battery life of 240km, and the fuel consumption is as low as 5.6L/100 km under the power feeding condition (5.6L/100 km is the fuel consumption of the heat engine under CLTC condition), achieving long cruising range and ultra-low energy consumption. In addition, the active air intake grille and lower body height enable the new M7 to have an ultra-low drag coefficient of 0.298Cd. With the new intelligent range extension technology, the working condition and environment are intelligently identified, and the use strategy between the range extender and the motor is reasonably allocated, so that the power is better, the battery life is longer, the silence is better and the energy consumption is lower.

As a 250,000-class luxury SUV, Wenjie New M7 has established the image of the "ceiling" of smart price ratio in market segments. The official guide price of the new M7 series is: 249,800 yuan for the five-seat rear-drive version of M7Plus, 284,800 yuan for the five-seat four-wheel drive version of M7Plus and 309,800 yuan for the five-seat intelligent driving version of M7Max; The M7Plus six-seat rear-drive version is 269,800 yuan, and the M7Max six-seat intelligent driving version is 329,800 yuan.
