摘要
基于非完整系统和非保守系统的动力学守恒律存在的条件及形式,我们建立了一种求得力学系统近似解的方法。这种方法原则上也可用于常微分方程组近似解的计算。并以Appell-Hamel模型为例说明了这种方法的应用。
In this paper, an approximate method is established by using the existence and form of conservative laws of dynamicaI systems. This method is also used to compute the approximate solution of ordinary differential equations. Finally, the Appell-Hamel's nonholonomic model is discussed.
