| 摘 要： | 以动量的平移为基础,将质点系的动量向任一动点平移,得到质点系的动量主矢和动量主矩。由此导出一般的动量定理及其一系列的重要推论:如质心运动、刚体绕定轴转动、刚体平面运动、刚体绕定点运动、自由刚体运动……的微分方程。

| Abstract: | By momentum translation, momentum principal vecter and moment of particle system are obtained by transferring all its momentum to a given moving point , whereby deduced general momentum of theorems and a series of important inferences, differential equations of center-of-mass motion, about-fixed-axis rotation and plane motion of rigid body, motion of rigid body about a fixed point, motion of free rigid body, etc. . |
