变质量系统的“自心”运动定理及其应用

The Theorem and Its Application on the Core Motion of the Various Mass System

本文给出沿一固定几何轨迹运动的变质量系统，在以其轨迹为自然坐标轴时它的变质量系统的“自心”运动方程，讨论了某些文献上的有关问题．

With the Various mass System of motion along the given geometrical locus, the paper discusses the related Problems of some documents according to the core motion equation of the various mass system as the nature coordinate axis of the locus.
