摘　　要：研究变质量单面完整约束系统的Mei对称性 .给出变质量单面完整约束系统Mei对称性的定义和判据 ,得到Mei对称性的结构方程和守恒量 。In this paper, the Mei symmetry of variable mass systems with unilateral holonomic constraints is studied. The definition and criterion of the Mei symmetry of variable mass systems with unilateral holonomic constraints are given. The structure equation and conserved quantity of the Mei symmetry are obtained. An example is given to illustrate the application of the result.
