| 摘 要： | 本文尝试将静力学中向量向一点简化的思想推广用于动力学理论中．通过建立动量集的概念为中介．重新解释了动量定理与动量矩定理的内涵，深入揭示了动力学的本质．即力与运动之间的关系。

| Abstract: | The method of reduction of vector sets to a given centre is often applied in statics. In this paper, we try to extend the method to dynamics. By constructing the concept, set of momentum,both the theorems of momentum and the theorems of moment of momentum are explained again.The essence of dynamics, that is, the relationship between the forces acting on the system and the motion of the system is revealed further. |
