摘　　要：研究了变质量非完整系统的3类对称性和由3类对称性导致的守恒量,给出了系统在无限小变换下3类对称性的定义、判据以及三者之间的关系,进而给出了由3类对称性直接导致的和间接导致的守恒量.The three symmetries of a variable mass nonholonomic system and thus resulted conserved quantities are studied. The definition, criterion and relationships of the three symmetries are given under infinitesimal transformation, and then, the direct and indirect conserved quantities from them are given.

关 键 词：变质量 非完整系统 对称性 守恒量
