一、引言三十年来水力学的研究发展史,从某种意义上来说,也就是一部水利工程的研究发展史。因此,对水力学研究发展动态的介绍,不可能不涉及到水利工程的若干方面,即主要指水利和水电等方面。至于水运,因它本身的特殊性,涉及到交通运输方面的问题较多,故本文不予涉及。另外根据传统的分科和分工,水文学也有它自身的独立体系,本文也不予涉及。但即使如此,在新兴的水资源系统和环境学中,既有水力学范畴的内容,也有水文学范 First, the introduction Thirty years history of hydraulics research and development, in a sense, that is, a history of water conservancy research and development. Therefore, the development of hydraulic research on the dynamic presentation, it is impossible not to involve a number of aspects of hydraulic engineering, that is mainly referring to water conservancy and hydropower. As for water transport, because of its own particularity, involving more transportation problems, so this article will not be involved. In addition, according to the traditional sub-division and division of labor, hydrology also has its own independent system, this article will not be involved. But even so, in emerging water systems and environmental sciences, there is both hydraulics and hydrology
