摘　　要：研究了非完整系统的Mei对称性直接导致的另一种守恒量,给出了这种守恒量的函数表达式和导致这种守恒量的条件方程.利用该方法比以往更易找到守恒量,最后举例说明了新结果的应用.This paper is intended to study a new conserved quantity as a direct result of the Mei symmetry for non-holonomic systems.The expression of such a new conserved quantity and its condition equation are presented here.It is easier to find out conserved quantities than ever by using above method.An example is showed to explain the application of the new results.
