摘　　要：研究机电系统的统一对称性.由系统的Lagrange-Maxwell方程,给出系统的统一对称性的定义和判据,得到了系统的统一对称性导出Noether守恒量,Hojman守恒量和Mei守恒量.举例说明结果的应用.The unified symmetry of mechanico-electrical systems are studied in this paper. The definition and criterion of unified symmetry of mechanico-electrical systems are derived from the Lagrange-Maxwell equations. The Noether conserved quantity, Hojman conserved quantity and a new conserved quantity deduced from the unified symmetry are obtained. An example is given to illustrate the application of the results.

关 键 词：机电系统 统一对称性 守恒量
