关于刚体运动学中建立动系的问题

Issues Concerning the Establishment of Motion System in the Rigid Motion Dynamics

本文强调指出，刚体运动学中，既可建立与刚体相固连的动系，也可建立与刚体不固连的动系，刚体运动学公式的形式均不受影响，究竟应怎样建立动系，完全视问题研究的方便而定，从而消除了某些文献就此问题可能导致的疑惑。

This paper has pointed out that in the rigid motion dynamics fixed motion system as well as non-fixed motion system can be established,which does not affect the form of the formulas expressed in the rigid motion dynamics. Therefore,how to establish motion system depends on the issues under study. The conclusion of this paper may help clear doubts from some literature concerning the issues.
