钱学森对近代力学的发展所做的贡献

CONTRIBUTIONS TO DEVELOPMENT OF MODERN MECHANICS BY H.S. TSIEN

钱学森先生为了研究实现高速飞机和远程火箭的可能性，在空气动力学、固体力学、稀薄气体力学和飞行力学等应用力学领域做出了杰出的贡献；并且开创了喷气推进学、工程控制论和物理力学等技术科学新分支．他对近代力学以至技术科学的内涵和发展方向，发表过全面系统的论述．在这篇文章中将介绍他的主要研究成果，并对他的科学思想作一初步的探讨．

In order to investigate the possibility of realizing the high-speed flight with supersonic airplanes, rockets and guided missiles, Professor Hsue-Shen Tsien has made great contributions to research and development in the fields of Aerodynamics, Solid Mechanics, Flight Mechanics; and has founded several new branches in Engineering Sciences, i.e., Jet Propulsion Science & Technology, Engineering Cybernetics and Physical Mechanics, etc. Furthermore, he has made systematic exposition of the intension and development orientation for Modern Mechanics as well as Engineering Sciences. In this paper, his brilliant research work is introduced, and his foresighted scientific thought is explored and discussed tentatively.
