摘　　要：理论力学的静力学不仅具有实用的特点,而且具有严密的逻辑体系结构.从逻辑的角度出发,对理论力学中作用在刚体上的等效力系归纳总结出的几个性质,并结合作用在刚体上的力系简化过程给出这些性质的具体应用.From the logical view, several properties of equivalent forces system are proposed, and their application in the procedure of simplification of forces system acting on a rigid body is illustrated by two examples. For deformable bodies, an elemental property of equivalent forces system is concisly mentioned.

关 键 词：运动效应 变形效应 力系等效 刚体
