Alternate member of the 9th-12nd CPC Central Committee, Vice Chairman of the 6th, 7th and 8th Chinese People's Political Consultative Conference, Chairman of the First Council of China Automation Society, Honorary Chairman of China Aerospace Society and China Systems Engineering Society, Executive Chairman of the Presidium of China Academy of Sciences, Member of the Department of Mathematics and Physics, Academician of China Academy of Sciences and Academician of China Academy of Engineering. 1986 was elected as the chairman of the Third National Committee of China Association for Science and Technology. 199 1 was awarded honorary chairman of China Association for Science and Technology by the Fourth National Committee of China Association for Science and Technology. He has made pioneering contributions in the fields of applied mechanics, jet propulsion, engineering cybernetics, physical mechanics and system engineering. At the beginning of 1956, he presided over the formulation of the report on "Jet and Rocket Technology Construction", the 37th national major scientific and technological task in the long-term scientific and technological development program from 1956 to 1967, and put forward "Opinions on Establishing China's National Defense Aviation Industry" to the State Council in February 1956, taking the lead. He has served as a technical leader in the development of rockets, missiles and spacecrafts for a long time, played a great role in organizing and leading the development of launch vehicles and spacecrafts in China, made outstanding contributions to the rapid development of China's missile and space undertakings, and contributed to the development of science and technology in many fields. 1957 won the first prize of Natural Science Award of China Academy of Sciences. 1985 won the national special prize for scientific and technological progress. 1June, 989, was awarded the titles of "Little Rockwell Medal", "World-class Science and Technology and Engineering Celebrity" and "Honorary Member of International Institute of Technology". 199 1 year 10 was awarded the honorary title of "National Outstanding Contribution Scientist" and the first-class hero model medal by the State Council and the Central Military Commission. He is the author of Engineering Cybernetics, Lectures on Physical Mechanics, Introduction to Interstellar Navigation and Systems Engineering.

Qian Sanqiang: Qian Sanqiang (19 13 ~ 1992), 1937 went to study in France. Under the guidance of Mr. and Mrs. Joliot-Curie, he studied nuclear physics in Curie Laboratory of Radium College of Paris University and Nuclear Chemistry Laboratory of French College. 1940 received a doctor's degree from France, and has served as a researcher and research tutor at the French National Center for Scientific Research. 1946 was awarded the Henry de Beauvais Prize by the French Academy of Sciences. During his study and research in France, he made continuous achievements in the field of nuclear physics. 1938- 1939 he cooperated with I Joliot-Curie to hit uranium and thorium with neutrons to obtain radioactive lanthanum isotopes, which was a strong support for explaining the nuclear fission phenomenon discovered soon at that time; 1944, he first determined the relationship between the range and energy of low-energy electrons below 50000 electron volts theoretically and experimentally; In 1946, the fine structure of praseodymium α ray was measured for the first time. With whom 1946- 1948 cooperated, we discovered the three-division and four-division phenomena of uranium, and comprehensively discussed the three-division phenomenon from both experimental and theoretical aspects, which has been recognized after more than ten years of inspection. His research results on nuclear fission have attracted the attention of physics circles all over the world. From 65438 to 0948, he returned to China and served as director of the Institute of Atomic Energy and vice president of the Academy of Sciences, which played an important role in organizing and leading the development of atomic energy in China. Mechanics and mathematicians. People from Wuxi, Jiangsu. 1935 graduated from Tsinghua University. 1942 received a doctorate from the University of Toronto, Canada. President and professor of Shanghai University. Mainly engaged in mechanics, applied mathematics and other aspects of research and teaching work and achieved outstanding results. He is one of the founders of many academic institutions. The eigen theory of thin shell is studied and established, and the nonlinear differential equation of shallow shell theory is put forward. The research of generalized variational principle and finite element theory has made many outstanding achievements. A unique view on the theory of motor calculation is put forward. Many effective suggestions are put forward for education, science and technology, economy and so on. He made an important contribution to the development of education.
