摘要
本文包括对刚体力学中两个教学问题的讨论：（１）关于有限转动不是矢量的论证；指出论证中所用的有限转动的转轴不应是空间固定轴，而应是本体固定轴。（２）刚体定点转动的自转轴和转动瞬轴；分析了两者在物理意义上的不同。
Two topics in tcaching rigid body mechanics are discussed,and the following opinfonsare claimed．（1)When proving that a finite rotation can not be represented by a vector，the axes ofthe fiiiite rOtations should be fixed to the body frame instead of the space frame。（2)The differencebetween spin axis and instantaneous axis should be emphasized in teaching rotation of rigid body abouta fixed point.
