键图理论是60年代发展起来的一门新学科,它是研究工程系统动态性能的有力工具。经过20多年的发展,目前应用已日趋广泛。近年来国内也应用这一理论对液压及其它物理学系统作为一些研究,但到目前为止,国内尚无系统地介绍这一理论及其应用的专业书籍出版,本连载讲座可以填补这一空白。相信本讲座定能为推动这一理论的广泛应用做出贡献。本连载讲座从本期起,计划分三期系统而简要地介绍这一理论及其在电工、机械和液压工程领域中的应用,最后还将介绍如何根据已绘出的键图列写状态方程,目的是希望有更多的读者掌握这一有力工具,用以研究各种工程系统的静、动态特性。
Keygraph theory is a new discipline developed in the 1960s, which is a powerful tool to study the dynamic performance of engineering systems. After more than 20 years of development, the current application has become increasingly widespread. In recent years, this theory has also been applied to some researches on hydraulics and other physical systems in our country. So far, however, there has been no systematic publication of this book on the theory and its application in our country. This serial lecture can fill this gap. I believe this talk will certainly contribute to the wider application of this theory. This series of lectures from this issue, the plan is divided into three phases and a brief introduction to the theory and its application in the field of electrical, mechanical and hydraulic engineering, and finally how to write the equation based on the key map has been drawn equation , The purpose is to hope that more readers have mastered this powerful tool to study the static and dynamic characteristics of various engineering systems.
