Form invariance of Gibbs-Appell equations for variable mass holonomic systems

建立变质量完整系统的Gibbs Appell方程 ,给出该方程在无限小群变换下形式不变性的定义和判据 ,并在确定的条件下由不变性引导出守恒量 .

In this paper,the Gibbs Appell (G A) equations for variable mass holonomic systems were established,then the definition and criterion of the form invariance of G A equations under the infinitesimal transformations of groups were given. Next, a conserved quantity can be deduced by using this form invariance under certain conditions, and an example was given.
