这份报纸集中于学习一个概括 Birkhoffian 系统的集成方法。为一个概括 Birkhoffian 系统的动态方程的参数上的变化的方法被介绍。为解决这个问题的过程能被划分成二步:第一步,辅助方程的一个系统被构造,它的一般解决方案被给;第二步,参数被改变,并且这个问题的答案被使用概括正规转变的性质获得。为概括 Birkhoffian 系统的参数上的变化的方法具有通用意义,并且我们作为例子拿一个 nonholonomic 系统和一个 nonconservative 系统说明这份报纸的结果的应用程序。
This paper focuses on studying the integration method of a generalized Birkhoffian system.The method of variation on parameters for the dynamical equations of a generalized Birkhoffian system is presented.The procedure for solving the problem can be divided into two steps:the first step,a system of auxiliary equations is constructed and its general solution is given;the second step,the parameters are varied,and the solution of the problem is obtained by using the properties of generalized canonical transformation.The method of variation on parameters for the generalized Birkhoffian system is of universal significance,and we take a nonholonomic system and a nonconservative system as examples to illustrate the application of the results of this paper.
