| 摘 要： | 本文从实例出发，对刚体的平动运动进行了分析、讨论，由此得出的结论是：从运动学角度看，作平动运动的任一刚体都可简化为一个质点；但是在一般情况下，根据它的动力学特征，刚体不能简化为质点。

| Abstract: | Proceeding from a concrete instance, the article analyses a rigid body translation, and draws a conclusion: In view of kinematics, any translating rigid body can be regarded as a simplified particle. However, in general situation, a rigid body can not be simplified on the basis of its dynamics character. |
