事件空间中非完整系统的守恒律

Conservation Laws of Nonholonomic Systems in Event Space

首先给出了事件空间中的 Ｄ’ Ａｌｅｍｂｅｒｔ＿ Ｌａｇｒａｎｇｅ 原理；其次基于该原理在无限小变换群作用下的不变性，得到了事件空间中非完整系统的守恒律；最后举例说明结果的应用．

Firstly,this paper presents the D'Alembert_Lagrange principle in the event space.Secondly,it obtains the conservation laws of nonholonomic systems in the event space,which are based upon the invariance of the principle under the infinitesimal transformations.Finally,it gives an example to illustrate the application of the result.
