China scientist Qian Xuesen. He was born in Hangzhou, China, and graduated from Shanghai Jiaotong University and the United States. He first studied at MIT, then got a master's degree, and then went to California. Director of the Institute of Mechanical Engineering of China Academy of Sciences, who helped China build the first rocket and missile.
Professor Qian Xuesen is a modern physicist in China and a world-famous rocket expert.
Born in Hangzhou, Zhejiang191year1February1day, born in Shanghai.
1934 studied at MIT and Caltech.
After receiving his doctorate from 65438 to 0938, he stayed in school to teach and engage in rocket research.
1947- 1955, he was a professor at MIT and Caltech.
1955 10 After returning to China through various obstacles, he served as the director of the Institute of Mechanics of Chinese Academy of Sciences, the vice minister of the Seventh Ministry of Machinery Industry, and the vice director of the Commission of Science, Technology and Industry for National Defense.
Qian Xuesen put forward an extremely important implementation plan for the development of rocket and missile technology in China.
From April, 65438 to April, 0956, he served as a technical leader in the development of rockets, missiles and spacecraft for a long time, and made great contributions to the cause and development of rockets, missiles and aerospace in China.
Qian Xuesen used to be vice chairman of Chinese People's Political Consultative Conference, member of the Department of Mathematics and Physics of China Academy of Sciences, honorary chairman of China Aerospace Society and chairman of China Association for Science and Technology.
I. Resume Qian Xuesen (19 1 1~X) is a scientist and rocket expert in China. He was born in Shanghai in191/and came to Beijing with his father when he was 3 years old. 49666.68668686666
Later, he stayed in the United States as a lecturer, associate professor, professor, director of supersonic laboratory and director of Guggenheim Jet Propulsion Research Center.
1950 began to work hard to return to the motherland, persecuted by the American government, and lost his freedom. 1955 took five years to return to the motherland, and since 1958, he has been the technical director of rocket, missile and spacecraft development for a long time.
1959, joined the China * * * production party.
He is currently the honorary chairman of China Association for Science and Technology.
Two. Scientific Achievements Qian Xuesen served as the technical director of China's rocket and space program for a long time, and made great pioneering contributions in space technology, system science and system engineering.
Qian Xuesen published 7 monographs and more than 300 papers.
The main contributions are as follows: ① Applied Mechanics Qian Xuesen has done pioneering work in aerodynamics and solid mechanics of applied mechanics.
The research on compressible boundary layer carried out in cooperation with von Carmen reveals some temperature changes in this field, and the Carmen-Qian Xuesen method is established.
In cooperation with Guo Yonghuai, the concept of upper and lower critical Mach numbers is introduced into transonic flow for the first time.
(2) Jet Propulsion and Aerospace Technology From the 1940s to the early 1960s, Qian Xuesen put forward some important concepts in the field of rockets and aerospace: in the 1940s, he put forward and realized the JATO, which shortened the runway distance; 1949, put forward the concept of rocket passenger plane and the idea of nuclear rocket; 1953 studied the possibility of interplanetary flight theory. In "Introduction to Interstellar Navigation" published by 1962, the concept of a round-trip transportation system between heaven and earth is put forward, in which a large aircraft equipped with a jet engine is the first-stage vehicle and an aircraft equipped with a rocket engine is the second-stage vehicle.
(3) Engineering Cybernetics In the process of its formation, the engineering practice of designing stability and guidance systems is the main research object.
Qian Xuesen himself is the pioneer of this kind of research work.
④ Physical Mechanics Qian Xuesen's research on combining the physical, chemical and mechanical properties of rare gases in 1946 is a pioneering work.
1953, he formally put forward the concept of physical mechanics, and advocated to determine the macroscopic mechanical properties of matter from microscopic laws, which changed the previous method of measuring mechanical properties only by experiments, greatly saved manpower and material resources, and opened up a new field of high temperature and high pressure.
196 1 year, the Lecture Notes on Physical Mechanics edited by him was officially published.
Now the leader of this subject is Professor Gou Qingquan. 1984, Qian Xuesen suggested to Gou Qingquan that physical mechanics should be extended to the engineering and technical field of atomic and molecular design.
⑤ Systems Engineering Qian Xuesen not only refined the practice of China aerospace systems engineering into the theory of aerospace systems engineering, but also put forward the concept of the overall design department of national economic construction in the early 1980s. He also insisted on applying the concept of aerospace system engineering to the whole country and national economic construction, and discussed the social system from the perspective of social form and open complex giant system.
The social form of any society has three aspects: economic social form, political social form and ideological social form.
Qian Xuesen proposed to divide the social system into three parts: social economic system, social political system and social consciousness system.
Corresponding to the three social forms, there should be three kinds of civilization construction, namely, material civilization construction (economic form), political civilization construction (political form) and spiritual civilization construction (ideology).
The construction of socialist civilization should be the coordinated development of these three civilizations.
From a practical point of view, it is social system engineering that ensures the coordinated development of these three civilizations.
From the reality of reform and opening up, we need not only economic system engineering, but also social system engineering.
⑥ System Science Qian Xuesen's most important contribution to system science is that he developed systematics and methodology of open complex giant systems.
⑦ Thinking Science Artificial Intelligence has become a hot topic in the world, but academic thoughts are in a state of chaos.
In this context, Qian Xuesen stood at the forefront of the development of science and technology, proposed the establishment of noeticscience Science and Technology Department, and scientifically summarized the ideas that had been discussed and debated in China's philosophical circles in the 1930s, but could not be clearly stated at that time.
The outstanding contributions are as follows: (1) In the early 1980s, Qian Xuesen proposed the establishment of the Department of Thinking Science and Technology, and thought that thinking science is a science dealing with consciousness and brain, spirit and matter, subjective and objective, and it is a major department of modern science and technology.
The need of computer technology revolution has promoted the scientific research of thinking.
(2) Qian Xuesen advocated that the development of thinking science should be combined with the work of artificial intelligence and intelligent computers.
According to his personal experience in developing applied mechanics, he pointed out that the research of artificial intelligence and intelligent computer should take applied mechanics as a reference, take the road of integrating theory with practice, and actually need theoretical guidance.
The theoretical basis of artificial intelligence is the basic scientific thinking in thinking science.
The way to study thinking is to look for it from the achievements of philosophy, and thinking actually evolved from philosophy.
He also believes that the study of thinking in images ...
