摘　　要：对Lagrange系统和Hamilton系统Mei对称性的研究表明 ,Mei对称性的两种表述对Lagrange系统是等价的 ,给出一类Mei对称性 ,而对Hamilton系统不等价 ,给出两类Mei对称性 .In this paper, the symmetries of Lagrange system and Hamilton system have been studied. It is indicated that two kinds of description of Mei symmetry are equivalent for Lagrange system so only one kind of Mei symmetry can be given; however I they are not equivalent for Hamilton system, so two kinds of Mei symmetry can be given.
