Tang Aoqing once taught inorganic chemistry in Jilin University? Physical chemistry? Material structure? Quantum chemistry? More than a dozen courses such as statistical mechanics often teach two or even three at the same time. With a rigorous and scientific course content system and unique teaching style, we have done pioneering work in the teaching of basic courses and cultivated a number of solid basic theories. A rigorous lecturer?
With the gradual improvement of the professional level of teachers of basic courses in chemistry department, the teaching work in Tang Aoqing has reached a new level, and the work of cultivating young scholars has been extended from schools to the whole country? By mentoring graduate students? Take a refresher course? Academic seminars and other forms to cultivate higher-level professional basic theory talents? Entrusted by the Ministry of Education, he and Lu Jiaxi? What about Wu? Xu Guangxian and other professors, successively in Qingdao 1953? From 65438 to 0954, two summer refresher courses on material structure were held in Beijing, which trained the first batch of material structure teachers in China. 1958— 1960? During the period from1963 to1965, the symposium on polymer physical chemistry and the symposium on material structure were held successively in Changchun. In these two seminars, Tang Aoqing opened a series of courses on polymer physical chemistry and group theory and their application in material structure for the first time in China? 1978 ——1980, with Jilin University as the main school and Shandong University as the joint school? Beijing Normal University? Xiamen University? Sichuan University? Yunnan University and Northeast Normal University jointly held a quantum chemistry research class and an advanced class in Changchun. These students come from universities and research institutes all over the country, including universities in China and Britain. 259 young teaching and research personnel? Since then, several short-term workshops have been held, 65438+April 0985? 1July, 987 successively in Fudan university? Nanjing University held a workshop on micro-reaction dynamics, 1986, 1988 held a teaching and research course on quantum chemistry with Xu Guangxian in Changchun in the summer? 1989 summer, held polymer scaling theory seminar in Changchun and the whole country? From 1953 to 1966, Tang Aoqing directed the material structure successively. More than 20 graduate students majoring in polymer physical chemistry; Since 1978 resumed the postgraduate system, 14 doctoral students have been enrolled? 26 master students?
Through the training and scientific research work of the symposium on polymer physical chemistry and the symposium on material structure, a number of high-level academics such as Sun Jiazhong emerged. Where's ginger? Deng Conghao? Liu Ruozhuang? Zhang Qianer? Yan guosen? Dai Shushan? Shen Jia? What about Tang Xinyi and the others? With his own teaching and scientific research practice, Tang Aoqing has provided important experience for the training of senior professionals in some basic disciplines, which can basically stand in China?
Tang Aoqing made outstanding contributions to the construction and development of Jilin University during his leadership of the education work of Jilin University? From 65438 to 0956, he served as vice president, assisted by the famous educator President Kuang Yaming, which made the school develop rapidly, and Jida entered the ranks of national key comprehensive universities from 65438 to 0959? 1978 has been the president of Jilin university, presiding over and leading the overall work of the school, and consciously implementing the spirit of "being both an education center and a scientific research center". New progress has been made in various undertakings of the school, and some new breakthroughs have been made in improving the teaching quality and scientific research level? Tang Aoqing is the main pioneer of quantum chemistry in China. For decades, he has always grasped the new trends of international academic frontiers and explored new topics. In order to catch up with the international advanced academic level and achieve a series of outstanding achievements, it has or will have a far-reaching impact on molecular design and synthesis of new materials? In the early 1950s, Pizel, a famous American quantum chemist, revealed the effect of "C-C single bond in ethane molecule is hindered from internal rotation"? On this basis, Tang Aoqing put forward a formula, namely potential energy function formula, which can be used to calculate the energy variation law of many complex molecules by using the existing data and materials abroad. Some properties of matter can be calculated by this formula, which provides a theoretical basis for changing the properties of matter from the molecular structure? After the publication of 1955, Wilson, a famous American quantum chemist, spoke highly of it and was widely quoted in textbooks and academic monographs at home and abroad. 1957 won the first natural science prize in China-the third prize awarded by China Academy of Sciences?
In the early 1960s, China engaged in lasers? Complex extraction? A lot of experimental research work has been carried out in the fields of catalysis and other disciplines, and a large amount of data has been accumulated, so it is urgent to summarize the laws in theory? The important distributive potential field theory of chemical bond theory is the basic theory needed in the above fields, but it is far from perfect? Tang Aoqing immediately took this important scientific frontier as the research direction, led the backbone members of the symposium on material structure, creatively developed and improved the coordination field theory and its research methods in more than two years, successfully defined the coupling coefficient between three-dimensional rotating group and molecular point group, established a set of irreducible tensor methods from continuous group to molecular point group, further unified various schemes in the coordination field theory, and put forward new schemes? This research achievement was rated as one of the top ten outstanding achievements by 1966 Beijing International Summer Physics Symposium. The symposium held that this achievement "enriched and developed the coordination field theory and provided a new theoretical basis for the development of catalysts and laser emission in chemical industry". And won the first prize of National Natural Science Award with 1982?
In the early 1970s, molecular orbital graph theory, as a new important branch of theoretical chemistry, attracted extensive attention from international academic circles? And Jiang zai 1975? For more than ten years, a series of new mathematical skills and model methods have been put forward and developed. His main contribution is to put forward three theorems (calculation of characteristic polynomial? Calculation of molecular orbital coefficient and symmetry reduction), so that this formal system of quantum chemistry can be expressed as the reasoning form of molecular diagram, which is universal, intuitive, simple and clear, and deepens the understanding of chemical topological laws? Tang Aoqing further applied this achievement to the study of molecular systems containing repeating units, and obtained very regular results? Based on the above contributions, the research achievement of "Molecular Orbital Graph Theory and Method and Its Application" won the first prize of the National Natural Science Award 1987?
1956, inspired by the national 12-year scientific development plan, Tang Aoqing turned to the study of the relationship between polymer reaction and structure to solve the problem of synthesis and modification of polymer materials urgently needed for national construction. His polymer physical chemistry research group (including students in academic discussion class) polycondensated the main polymer reactions? Cross-linking curing? Add it up? Copolymerization and cracking are studied in depth one by one? The gelation theory is developed into sol-gel distribution theory, and the concept of sol reactivity which is easy to measure is introduced, so that the research scope is extended from before the gel point to the whole process. Using the concepts of critical reactivity and maximum reactivity, the theoretical prediction range is extended from gel point to gel interval and gel surface. The corresponding correction parameters are introduced, and the assumptions of equal activity and inner ring are deleted, thus forming a complete polymer curing theory, which has been widely used in domestic coatings and solid propellant industries? In the field of addition polymerization, a new method of solving kinetic equation by probability theory is proposed, which contributes to solving Ricatt equation, and is summarized as graphic analysis method, which is developed into a unified theory of the relationship between reaction mechanism and molecular weight distribution, and the segment distribution and molecular weight distribution function of copolymer are derived from this. The five aspects of polymer reaction have formed a system with obvious characteristics. With the establishment and development of statistical theory of polymer reaction, the quantitative relationship between polymer structure and reaction parameters has been established. It provides a theoretical basis for designing products with predetermined structure and determining reaction conditions, production technology and formula. He and his research group have been working in the field of statistical theory of polymer reaction for 30 years, and the main research result is polycondensation. The statistical theory of addition polymerization and crosslinking reaction won the second prize of National Natural Science Award 1989?
In the past 65,438+00 years, Tang Aoqing has conducted scientific research in other new fields and achieved gratifying results? In the mid-1970s, he keenly noticed that cluster chemistry had become an important research field in the world? In recent ten years, based on the relationship between the chemical bond properties and structural rules of cluster compounds, and on the basis of quantum chemical calculation of the chemical bond properties of alkanes and polyhedral alkanes, he classified them according to the relative size of the number of vertices and faces of their skeleton polyhedrons, and established theoretical models suitable for many cluster compounds (including blocked polyhedrons and fused boranes, polyhedral alkanes? Unified topological structure rules of carborane and transition metal nitrogen borane, multilayer sandwich compounds, transition metal carbonyl compounds and molybdenum-iron-sulfur clusters. ) has been used to explain the structures of more than 600 known compounds, and satisfactory results have been obtained, revealing the relationship between chemical bonds and geometric structures among the above compounds? In recent years, Tang Aoqing and his collaborators have opened up a new field on the basis of the statistical theory of polymers, that is, the study of polymer curing theory and scale. He systematically summarized the changes before and after gelation in various crosslinking and polycondensation reactions, solved the problem of sol-gel distribution, and put forward various gelation conditions with important application value. Especially from the concept of modern scale, the process of sol-gel phase transition is revealed in essence, and the generalized scale law marking this transition is obtained. At present, the characterization of polymer curing is being deeply studied? Tang Aoqing has always advocated that college teachers should be engaged in both teaching and scientific research, and must have both abilities? Because they complement each other? Complementary? Teachers engaged in teaching should have a wide range of knowledge, but without scientific research, teaching will not reach its due depth and teaching quality will not be improved; Teachers engaged in scientific research should have deep knowledge in a certain field, but without teaching, they can't broaden their knowledge and it is difficult to improve their scientific research level?
He has always attached importance to teaching and practiced it. Even in his old age, he still insisted on the front line of teaching and continued his pioneering teaching work? The reaction of teachers and students to his lectures is: "Mr. Tang always listens to new lectures and always keeps the fresh content of international level?" Some said, "Listening to Mr. Tang's lecture is like an artistic enjoyment?" Tang Aoqing suffered from high myopia when he was young. Since he studied in university, he has an amazing memory. Therefore, when preparing lessons, he mainly relied on thinking and memory. He only wrote a simple outline and went to the pulpit. The lectures in simple terms were logical and enlightening? His unique lecture style can make teachers and students highly concentrated in class and interweave their thinking activities, which is very effective in improving teaching effect? His extensive knowledge and exquisite lecture art have a far-reaching influence on the training of young and middle-aged teachers?
Tang Aoqing often educates his research group to treat scientific research achievements correctly and pay attention to strengthening the construction of scientific research ethics? In his view, the achievement of a scientific research result is often the result of the cooperation of many people. Teachers and teaching assistants, colleagues and colleagues must respect each other? Contributing comrades must respect the work of others; Older comrades should pay attention to training young comrades, tell them their own ideas, and give them the topics they have considered to achieve results. We old comrades must respect their work? On the issue of the signature of published papers, Tang Aoqing's principle is: "This is my main idea, and I have worked hard, so my name can be put in front; It was completed under my guidance, and my name was put behind it; I only made some suggestions, so I can't write my name? 1982 after Tang Aoqing was elected as the chairman of the 2nd1Council of chinese chemical society, he attached great importance to the work of the society and advocated that chemistry should inherit and carry forward the predecessors in the chemical field? The fine tradition of the old chairman unites the national chemical industry, and Qi Xin works together to develop the chemical industry of the motherland? He practiced himself and made positive contributions to maintaining academic unity, establishing excellent style of study and meeting, and improving the academic level of chemistry in China. He also made some reforms to chinese chemical society's leadership system, and worked with three other directors, Lu Jiaxi? Yan Dongsheng? Professor Qian Renyuan co-sponsored the establishment of the executive chairman system, each serving for one year, which promoted the democratic unity of the society?
1986 At the beginning of this year, as one of the important decisions of the national science and technology system reform, the State Council decided to set up the National Natural Science Foundation Committee, and Tang Aoqing was appointed as the first director of the fund? In a relatively short period of time, he carefully formed a leading group composed of capable cadres; According to the central policy? Policy, multi-faceted investigation and study, solicit opinions extensively, and formulate a series of rules and regulations; The evaluation principle of "relying on experts, promoting democracy, supporting the superior and strengthening the strong, being fair and reasonable" was put forward, which successfully guided the evaluation of projects funded by the National Natural Science Foundation of China and won wide support from the scientific and technological circles? Under his leadership, the National Natural Science Foundation of China has given full play to the collective wisdom of scientists, which has enabled the NSFC to apply freely, actively organize, make overall arrangements and deploy in depth, and played a very important role in supporting basic research and applied basic research in China? Tang Aoqing has made great contributions to the establishment of a science fund system with China characteristics?
1979, Jilin University was entrusted by the Ministry of Higher Education to undertake the Journal of Chemistry of China Universities. After preparation, it was officially published on 1980, and the English version was published at the same time from 1984? Journal of Chemistry of China University is edited by Yang Shixian and Tang Aoqing, and has been edited by Tang Aoqing since Yang Shixian's death 1985? In his leadership work, Tang Aoqing relied on the collective wisdom of the editorial board, advocated imitating famous domestic and foreign sci-tech journals, and adhered to strict peer review system and serious editing style. With the increasing number of manuscripts, he put forward the principle of "living within our means" to strictly select manuscripts, thus ensuring the quality of publications? Most of the papers published in chemistry journals of universities in China are American Chemical Abstracts CA and Soviet Abstracts Magazine P? According to the fourth issue of American Chemical Abstracts Data Source Index (1989), CA has the largest number of 1000 journals in the world in this compilation year (July 1988 to June 1989), and the Journal of Chemistry of China University ranks 244th and 34th among the cited journals.
Tang Aoqing has always taken Premier Zhou Enlai's teaching "Never too old to learn, never too old to work, never too old to learn and never too old to reform" as his motto. He is still "a science with a strong heart, working hard for the prosperity of the country". In addition to the heavy administrative work of the National Natural Science Foundation of China, he goes back to Jilin University to give lectures and guide doctoral students every year. Often invited to brother colleges to give academic reports; Vigorously continue to lead the Institute of Theoretical Chemistry of Jilin University and the Theoretical Chemistry Research Group of the Department of Chemistry to explore new scientific fields? As he said to visiting reporters in April 1990, "We scholars of the older generation should make great efforts to train the younger generation. The reason why I have never given up teaching and scientific research since I was engaged in administrative work is because I think that cultivating young talents is a major event related to the future of our country? For the future of science in China and the prosperity of the motherland, I am willing to spend the rest of my life? "
