摘　　要：为了建立完善的多次复合运动理论,本文分别用矢量微分法和逐次递推法分析了点的多次复合运动,给出了点的速度合成定理与加速度合成定理;并分析了刚体的多次复合运动及其特征,导出了求刚体上任一点的绝对速度和绝对加速度公式。所给公式均具有一定的规律性和普遍性,为分析点和刚体的运动规律提供了一个方便的组合计算方法。In order to establish a perfect theofy for the multiple compound motion,the vector differential method and the successively deduced process are used respectively to analyze the multiple compound motion at a point in this paper.The theory of compound velocity and the theory of compound acceleration are given,and the multiple compound motion of rigid body and its characteristics are analyzed simultaneously,Formulas for the absolute velocity and acceleration at any point in a rigid body are deduced.The formulas have regularity and universality for any situation,and provided a convenient method of compound calculate for the law of motion of points and rigid bodies.
