JPL(美国喷气推进实验室)的陈介中博士应中国宇航学会的邀请于九月底至十一月九日来我国访问。现已圆满结束。陈介中博士是JPL的著名力学专家。在结构动力学方面造诣尤深,发表过许多篇著名文章。陈介中博士还是美国南加州华人科技中心主席,对中美两国的学术交流起了很好的促进作用。1979年曾来我国访问,满载盛誉而归。这次来华主要是系统地讲解结构动力学在宇航结构方面的应用与发展。一共分九讲即:(1)美国结构动力学发展近况;(2)矩阵方程式及结构动力分析;(3)广义冲击谱及航天器负载分析;(4)矩阵微扰在结构动力学上的应用;
Dr. Chen Jizhong of JPL (American Jet Propulsion Laboratory) came to China at the invitation of China Society of Astronautics from late September to November 9. Now the successful conclusion. Dr. Chen Jiezhong is a well-known mechanics expert at JPL. Proficiency in structural dynamics particularly deep, published many famous articles. Dr. Chen is also the chairman of the Chinese Southern California Center for Science and Technology in the United States and has played a very good role in promoting academic exchanges between China and the United States. In 1979, he visited China and returned home with great success. This visit to China mainly systematically explains the application and development of structural dynamics in the aerospace structure. A total of nine points that is: (1) the development of structural dynamics in the United States; (2) matrix equations and structural dynamics analysis; (3) generalized shock spectrum and spacecraft load analysis; (4) matrix perturbation in structural dynamics application;
