摘　　要：研究转动变质量相对论系统的Lie对称性和守恒量 .定义转动变质量相对论力学系统的无限小变换生成元 ,利用微分方程在无限小变换下的不变性 ,建立转动变质量相对论性力学系统的Lie对称确定方程 。The Lie symmetries and conserved quantities of the rotational variable mass relativistic system were studied. By defining the infinitesimal transformations generators and by using the invariance of the differential equations under the infinitesimal transformations, the determining equations of Lie symmetries for the rotational variable mass relativistic mechanical system are established. The structure equations are the forms of conserved quantities and obtained.
