事件空间中变质量非完整系统的守恒律

Noether's theorem of nonholonomic systems of variable mass in event space

给出了事件空间中的变质量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 ,得到变质量非完整系统的守恒律 ;

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