摘　　要：研究Vacco动力系统的一种新对称性:Mei-Lie对称性及其守恒量.给出Vacco动力系统的Mei-Lie对称性的定义和判据,提出受Vacco约束力学系统的Mei-Lie对称性导致的Mei守恒量和广义Hojman守恒量.最后给出一个例子说明结果的应用.In this paper, the Mei-Lie Symmetry, a new symmetry, and its conserved quantities of Vacco mechanical system are studied. The definition and the criterion of the Symmetry for the system are given. Presented in this paper is a theorem asserting that the Mei-Lie Symmetry for the system leads to both the Mei conserved quantity and the general Hojman conserved quantity. An example is finally given to illustrate the application of the result.
