Qian Weichang is one of the founders of modern mechanics in China. Good at applied mathematics, mechanics, physics, Chinese informatics, etc. At present, more than 20 academic monographs have been published, such as Great Disturbance of Circular Thin Plate, Mechanics of Elasticity, Variable Element Method and Finite Element Method, Armor-piercing Mechanics, Generalized Variational Principles and Applied Mathematics, and more than 200 academic papers have been published at home and abroad. He has made many pioneering achievements in scientific theory and engineering technology. The main academic contributions are the nonlinear intrinsic unified theory of plates and shells, the perturbation solutions and singular perturbation solutions of large perturbation problems of plates and shells, the generalized variational principle, the analytical solution of ring shells and the macro-glyph coding (money code) of Chinese characters. His early "large disturbance equation of shallow shell" was praised as "Qian Weichang equation" by international academic circles; On the large perturbation problem of circular thin plates, his perturbation method with central perturbation as a small parameter is called "Qian Weichang method" internationally. 1955 won the second prize of National Science Award issued by China Academy of Sciences for the work of circular thin plate with large disturbance, and the second prize of National Natural Science Award of 1982 for the work of generalized variational principle. In addition, a number of scientific research achievements won the Beijing and Shanghai Science and Technology Progress Awards respectively. Recently, Professor Qian Weichang's work on Fick's plate and shell Shikhov-Rafe hypothesis theory is a new contribution to the basic theory of solid mechanics. 1997 won the "Science and Technology Achievement Award" in ho leung ho lee foundation.
Qian Sanqiang: Since the founding of New China, Qian Sanqiang has been committed to the development of atomic energy. He used to be the deputy director and director of the Institute of Modern Physics of Chinese Academy of Sciences (later renamed the Institute of Atomic Energy). From 65438 to 0958, he participated in the construction of atomic reactors by the Soviet Union and gathered a large number of nuclear scientists (including his wife). He also recommended Deng Jiaxian and other outstanding talents to the team developing nuclear weapons.
1960, after the central government decided to develop the atomic bomb entirely by self-reliance, Qian Sanqiang, who has served as the deputy minister of the Second Machinery Department, served as the chief technical officer and chief designer. On the eve of the 50th anniversary of the National Day, the Central Committee of China, the State Council and the Central Military Commission posthumously awarded Qian Sanqiang the "Two Bombs and One Satellite Meritorious Medal" made of 5 15g pure gold, in recognition of this leading scientist's great contribution. 1940, Qian Sanqiang obtained the French national doctor's degree and continued to work as an assistant with the second generation of the Curies. 1946 married a talented woman with the same theme. The husband and wife made a breakthrough in the study of uranium fission and were recommended to the world scientific community by their mentor Iorio. Many newspapers and periodicals in western countries published this story and praised "China and Curie discovered a new method of nuclear fission". In the same year, the French Academy of Sciences also awarded the physics prize to Qian Sanqiang.
Qian Sanqiang died on1June 28th, 992.
On June 365438+ 10, 2009, Qian Xuesen passed away.
