摘　　要：研究一般完整力学系统的Mei对称性直接导致的一种守恒量,给出系统的Mei对称性的定义和判据方程,得到系统Mei对称性直接导致的一种守恒量的条件和形式,并举例说明结果的应用.A kind of conserved quantity which directly results from the Mei symmetry of general holonomic mechanical system is studied in the paper. The definition and criterion of Mei symmetry for the general holonomic mechanical system are given. The conditions under which Mei symmetry can lead to a conserved quantity and the form of the conserved quantity are deduced. An example is given to illustrate the application of the resuh.
