RELATIVISTIC DYNAMIC EQUATION AND VARIATIONAL PRINCIPLE FOR ROTATIONAL VARIABLE MASS SYSTEM
转动变质量系统的相对论性动力学方程和变分原理

In this paper, Simultaneously considering the problem of classical variable mass and the relativistic effect of mass variation with velocity, the fundamental relativistic equation of dynamics, Dalembert principle and Lagrange equation for fixed-axis rotational variable mass system are built.
