Lei Qingquan, professor and doctoral supervisor of Harbin University of technology, academician of Chinese Academy of engineering. He graduated from Xi'an Jiaotong University in 1962. He studied in Hanover University of West Germany from 1981 to 1983. In 1993, he was employed as a visiting researcher of Osaka University in Japan, senior member of IEEE, and chairman of ieee-dei's ICPADM 2009 International Academic Conference; He is currently the chairman of the academic committee of "State Key Laboratory of electrical insulation for power equipment" (Xi'an Jiaotong University); Chairman of the academic committee of "State Key Laboratory of electronic thin films and integrated devices" (University of Electronic Science and Technology); He is an academician of Xi'an Jiaotong University and Qingdao University of science and technology, a part-time professor of Tsinghua University, Sichuan University, Shanghai Jiaotong University, Beijing Jiaotong University, Dalian University of technology, and a chair professor of Wuhan University; Chairman of Engineering Dielectric Committee of China Electrotechnical Society and member of dielectric physics Professional Committee of Chinese physical society; Member of the 9th and 10th National Natural Science Foundation of China. He has successively presided over and completed one key scientific and technological research project of the ninth five year plan, four projects of the National Natural Science Foundation of China, and 18 other scientific research projects. He won one second prize of National Technological Invention Award and one invention patent in 2001, two first prizes of provincial and ministerial level science and technology awards, and one second prize each. In 2009, he was awarded the honorary title of "60 years of new China moved Longjiang talents" in Heilongjiang Province.

On February 1, 2002, Professor Lei Qingquan won the second prize of national technological invention for his research achievement "preparation of new semi conductive poly quinone free radical polymer powder material and its sensor application". After 13 years of hard work, he led the research group to solve the scientific and technological problems of using semi conductive quinone black polymer powder materials to make pressure and temperature sensors in the world, and made important contributions to China's oil and gas development and revitalization of the northeast old industrial base construction. In 2017, he was elected academician of the Chinese Academy of engineering for 14 years. Without any project fund support, he made great achievements in the research of nano dielectric field in the world with persistent exploration and ideological innovation. The first named nanocell and superinsulator prototype obtained experimental verification, and obtained extremely high breakdown strength on nanostructured materials, The purpose of adjusting and controlling the properties of materials through structure construction is realized. This is a breakthrough in the field of nano dielectric research. It highlights the advancement of time, the innovation of scientific concepts, and the potential subversion of technology. Its impact is no less than that of the frontier or hot tracking papers published in science and nature journals. This achievement was published on nano energy, a famous international journal, and presented a special birthday gift for his 80th birthday.

Devote oneself to science and serve the motherland

Lei Qingquan was born in Zhonghe Township, Yuechi County, Sichuan Province in 1938. He lost his mother at the age of one and his father at the age of seven. When he was young, he followed his grandmother and lived by his aunt. After primary school, he dropped out of school because his family couldn't afford to study for him. When he was 13 years old, the village cadres found his home and made him enjoy the full state grants and living subsidies until he finished university. In his young mind, he knew that his family was difficult and it was not easy to read books. Therefore, he cherished the hard-earned opportunity to read books. In his spare time of weeding, digging the ground and transplanting rice seedlings, he took time to read books. Until now, he has maintained the good habit of loving reading. In 1957, Lei Qingquan was admitted to Xi'an Jiaotong University with excellent results. He studied under Professor Chen Jidan, the founder and founder of dielectric physics in China. His erudite and rigorous academic attainments and persistent research spirit deeply affected him, leading him to travel in the ocean of science, and also strengthened his faith in following his teacher's steps and firmly advancing along his research direction.

In 1962, after graduating from Xi'an Jiaotong University, Lei Qingquan resolutely obeyed the national assignment and came to Harbin Institute of electrical engineering to teach. From 1981 to 1983, Lei Qingquan was a visiting scholar at the University of Hanover, Germany, engaged in theoretical research on space charge in high voltage insulating materials. During this period, he clearly saw the disparity between China and developed countries. A strong patriotism made him secretly determined: what foreigners have done, we should do better; We should do what foreigners can't do; Scientific research is to strive for the first, only the first can be meaningful. During his study, he gave up all the opportunities of tourism and leisure, and even moved his luggage to the laboratory to study the theory and application of dielectric phenomenon, and determined to serve the motherland after his studies. Looking back on that experience, he said, "in my opinion, travel can be done at any time, but once a good opportunity for learning is missed, it will never come back."

"I lost my parents in my childhood. It was the party and the state that sent me to school to support my life. Only by working hard can I repay this kindness." Lei Qingquan told me with emotion. After returning to China, Lei Qingquan focused on the forefront of electrical insulation and related interdisciplinary research. At that time, how to solve the problem of continuous monitoring the pressure and temperature changes of underground formation in the production process of electric pump wells has been a worldwide scientific and technological problem. Due to the poor thermal oxidation stability of semi conducting polymer materials used in the preparation of monitoring sensors, especially the polyquinone free radical polymer (abbreviated as quinone black), its large-scale application has not been realized. Since 1962, American MIT scholar Pohl has made in-depth research on the properties of these materials with the support of the joint Navy, army and air force and Philips petroleum company. Although hundreds of quinone black have been synthesized, the problem that such materials can be used to make sensors has not been solved until Pohl's death in 1986. Based on the urgent need of new pressure and temperature sensors in domestic and foreign oil field markets, in 1987, Lei Qingquan set up a research group to tackle the international problems in this field with team members. Faced with the hard environment of no standard samples, no reference materials and even no production equipment, Lei Qingquan led the team to work hard and concentrate on research. With amazing perseverance and firm belief, Lei Qingquan spent 13 years, after hundreds of failures, It is the first time in the world to successfully develop a temperature and pressure dual parameter sensor made of semi conductive poly quinone powder material for downhole monitoring of electric submersible pump. At the evaluation meeting of the project's application for the National Technological Invention Award, many domestic experts repeatedly said: "this is original innovation, this is absolutely original innovation." What's more, the whole research and development process from sensor material, sensor design to sensor processing was completed by independent innovation led by Lei Qingquan, with a number of invention patents. In 2003, Lei Qingquan was elected academician of Chinese Academy of engineering. Zhao Qi, then president of Harbin Institute of technology, said with emotion: "Professor Lei Qingquan is an academician who has accumulated and developed on the barren land of Harbin University of technology."

In September 2009, academician Lei Qingquan was awarded the honorary title of "moving Longjiang talents" in Heilongjiang Province

Persevere, open up and innovate

Persistence and innovation are Lei Qingquan's insistence and pursuit of scientific spirit. He is good at standing at the height of the times and science, with forward-looking and pioneering ideas to grasp the research direction. Once the goal is confirmed, he will persevere and never give up until the goal is reached. Looking back on his many important achievements, we can see that he has gone through a ten-year process of sharpening his sword. He is ambitious and responsible, and he is not discouraged or defeated.

"The greatness of man is in the subtle flash." Professor Lei Qingquan always wears simple clothes, works properly and never extravagantly, which shows his open-minded and open-minded attitude towards life. Under the extremely difficult conditions of early scientific research, he often encouraged everyone to carry forward the spirit of arduous struggle during the long march of the Red Army. During the thermoluminescence study, he and his team members obtained three photon background noise test results under the military coat at night. In his daily life, his greatest hobby is reading. He takes the exploration of the unknown world as his greatest pleasure. He has achieved his basic knowledge of physics, material science, life science and information technology in dielectric theory, and has made his achievements in the preparation technology of conductive polymer sensors and his exploration ability in the frontier field of nano dielectric, And constitute a unique thinking concept. In the past 10 years, he still spent a lot of time reading articles in the international well-known journals Nature and science, and concerned about the thinking of top international scientists.

Lei Qingquan and members of the research group

On innovation, Lei Qingquan has his own experience: "innovation can not only focus on these bright spots that have begun to flash and heat in science, but also aim at the needs of national science and technology and economic development, and stick to a point with faint hope, which may lead to innovation."

He is a pioneer in the theoretical research of nano dielectric in China. As early as 2001, he was the first to undertake the key project of National Natural Science Foundation of China on nanocomposite polyimide materials in the field of electrical insulation. In the process of research, he was acutely aware of the existing problems, solutions and future development direction in the field of nano dielectric. Focusing on this "promising point" which has not attracted the attention of scientific research peers, he began to devote himself to the research. In 2009, he presided over the 354th Xiangshan scientific conference as the applicant and executive chairman of the conference. Xiangshan Science Conference is one of the top scientific conferences in China. It aims to explore frontier and strategic scientific issues, lead the development direction of scientific research, and provide decision support for the national high-level. The executive chairman of the meeting is a well-known scientist. Because the topic focuses on basic theory, it is rarely presided over by academicians of the Academy of engineering. In 2009, he was also the first scientist in our province to preside over the Xiangshan Science Conference.

At the meeting, academician Lei Qingquan gave a keynote report on "the structure and motion of nano dielectrics, the multi-level of space-time and its thinking". He pointed out that the study of nanodielectrics involves the interdisciplinary fields of condensed matter physics, materials science, surface and Interface Science, electrical engineering, electronic science and engineering, and information science and engineering, and involves the mesoscopic field of nano dielectric and corresponding structures that have never been studied before. Therefore, on the basis of the traditional dielectric microstructure macro performance theory, we should strengthen the research on the relationship between mesoscopic or nanoscale structure and microstructure and macro performance, and explore the establishment of the relationship and theoretical model of microstructure meso structure macro performance. This is the 3M relationship (micro micro mesoscopic macro macro macro), which is widely recognized in the field of nano dielectrics. It establishes the theoretical framework for the development of nano dielectrics and points out the research direction, which is highly praised by the industry. Aiming at this direction, he continued to tackle key problems for 8 years, and for the first time built a "prototype of a one-dimensional cellular superelectric insulator", and discovered the regulatory role of nanostructure on electron motion under high electric field. Undoubtedly, this original achievement will promote the revolutionary progress of nano dielectric research from technical type to scientific type, and win the prize again at the scientific research peak in the field of electrical insulation in the world.

It is worth noting that academician Lei Qingquan has done a lot of research work on the material structure, preparation technology and material characteristics of nano composite polyimide corona aging film materials. These work laid a foundation for the industrialization of this material in China.

Pragmatic and selfless dedication

"Falling red is not a heartless thing. It turns into spring mud to protect flowers more." As the leader of the discipline construction of high voltage and insulation technology in our university, he thought and grasped the development and construction of electrical engineering discipline with advanced strategic mind. He stressed that the focus of discipline construction is the construction of talent team. They should have strong professional basic knowledge, outstanding engineering practice ability and innovative thinking. More importantly, they should have the value pursuit of accumulation, foresight and dedication to science, and despise the mentality of complacency and self satisfaction. He stressed that in order to gain the affirmation of the peers in the discipline, it is necessary to continuously refine our own research direction and give full play to its own characteristics and advantages. Scientific research projects should be supported by an overall knowledge, and they must have the spirit of not looking at the small but only looking at the big, and making qualitative rather than just quantitative contributions to the discipline construction. In view of how to realize the leap forward development of the discipline, he thinks that the goal should be further, the mind should be broad-minded, and the pace should be slow and steady. Under his leadership, the discipline construction of electrical engineering in our university took only 10 years from the breakthrough of "zero" in 1997 to becoming a national key discipline in 2007.

In 2007, he made a long-term layout of the electrical engineering discipline platform with a forward-looking view. From the perspective of international science and technology development, he took the research of nano dielectric as a breakthrough in the discipline development. In order to build the pillar industry of new materials in Heilongjiang Province, Li Zhanshu, then governor of Heilongjiang Province, inspected the Key Laboratory of Harbin University of technology in 2009. He was inspired by academician Lei's dedication to science and put in place 39 million yuan of construction funds for the laboratory construction with nano dielectric characteristics proposed by him. The following year, the National Key Laboratory of dielectric engineering was approved for construction. In the same period, the state has invested 4.5 million yuan per year since 2010 to support the construction of key disciplines for five years. Sufficient funds have greatly enriched the basic environment of discipline development and Key Laboratory, and brought a new leap for the discipline development and construction of the school.

In 2009, Lei Qingquan, chairman of the conference, successfully held the International Conference on dielectric material properties and applications in Harbin Institute of technology, making Harbin University of technology the third university in China to hold the international conference after Tsinghua University and Xi'an Jiaotong University, which enhanced the exchange between the University and international academic peers. At the meeting, academician Lei Qingquan systematically introduced the theoretical framework of nano dielectric, which was widely concerned and highly appraised by the participants, and further expanded the international influence of our university in this field.

Inheriting knowledge and unswerving determination

"In 1991, after winning the Nobel Prize in physics, Professor de gener of France immediately spent two years in 1992-1993 doing modern popular science education on" soft matter and hard matter "in more than 200 senior high schools in France. Feynman, an American Nobel Laureate in physics, thinks that his greatest contribution is not Nobel Prize, but his" Feynman physics lecture notes ", which are popular for many generations The great quality of education has always been an example for me to learn from. " Professor Lei Qingquan not only insists on the basic course teaching of dielectric physics, but also takes inheriting knowledge and promoting posterity as his unswerving pursuit. In his 55 years of education career, he has been working in the front line of teaching and scientific research, working hard and quietly. No matter how busy his scientific research work is, he always insists on teaching undergraduate and graduate students, and undertakes the teaching of dielectric physics, quantum mechanics, solid physics, semiconductor physics, electrical properties of polymers, and optical properties of solids. He not only preached and enlightened the students, but also influenced and enlightened the students with the quality and personality charm of a scientist. He attaches great importance to the consolidation of students' theoretical foundation and practical skills. Every year, he selects students with strong innovation consciousness and practical ability from junior college students to participate in his research. Wang Fulai, an early graduate student and master's thesis of cable 86, was in the United States in 1990《 Published in the Journal ferrelectrics and included in SCI; Wang Xuan's thesis was published in j.appl.phys. In 1992 It has been cited by foreign scholars on SCI journals for many times; Feng Xuebing, his graduate student, was awarded the honorary title of "national top ten outstanding talents in the cross century" in 1996; In 1998, Zhang Qingyue, a graduate student under his guidance, won the second prize in the national "Challenge Cup" science and technology competition for making self limiting temperature cables with positive temperature coefficient, and became the only winner among the students in Heilongjiang Province.

After he was elected as an academician, Mr. Lei did not stop teaching and scientific research, indifferent to fame and wealth, and mapped the academician's aura in the teaching and research field he loved and adhered to. He has made more than 30 academic reports on the basic theory, materials and applications of Engineering dielectrics in different types of academician forums, universities and scientific research institutes. On April 24-25, 2007, Lei Qingquan delivered a series of special academic reports on "theoretical basis and research progress of Engineering dielectrics" at the academic exchange meeting for the 70th anniversary of the establishment of the electrical machinery Department of Tsinghua University, including the theoretical basis of dielectric physics, the space charge effect in dielectrics, and the research status, methods and thinking of nano polymer dielectric composites, Dielectric phenomenon and its modern application almost covered his whole life's scientific summary of the theoretical materials and applications of Engineering dielectrics, which was highly praised by experts and teachers and students. Although his monograph "structure and electrical properties of polymers" is not long, it is well received by the majority of students because of its concise words and simple language. The book is highly professional and has a limited number of prints, so students often queue up to read it in the library. Although he is old, he can keep pace with the times, seize the characteristics of young scholars who are good at using the Internet to access academic resources, and actively use the Internet to spread basic knowledge, which benefits more young scholars. His academic report "space charge effect in dielectrics" has been widely read on several influential data sharing websites, such as Baidu Library, douding.com, Sina Aiwen information sharing, daokebaba, etc., and its download volume has exceeded tens of thousands of times. It has been rated as a boutique PPT in Baidu Library and douding.com. Some netizens commented: all the explanations are based on the deep and extensive basic knowledge that others can't reach, which is easy to understand.
