本文研究了一个新的守恒量，称为广义Mei守恒量，它是由Birkhoff系统的Mei对称性直接推导出来的。给出了Mei对称性可以直接导出广义Mei守恒量的条件以及广义Mei守恒量的形式。并给出一个例子来说明结果的应用。
This paper studies a new conserved quantity which can be called generalized Mei conserved quantity and directly deduced by Mei symmetry of Birkhoff system. The conditions under which the Mei symmetry can directly lead to generalized Mei conserved quantity and the form of generalized Mei conserved quantity are given. An example is given to illustrate the application of the results.
