| 摘 要： | 从运动的叠加原理和定点运动的欧拉定理，按逻辑和理论的自洽性，说明定点运动的有限转角应是轴矢量；分析两次有限转动不能对易从而认为有限转角不是失量的例证的错误根源；阐述代表刚体定点运动的两种实际转动可以对易，从而论证刚体定点转动的有限转角的轴矢量性．

| Abstract: | On the motional superposition principle and the Euler Theorem, explain that the limited angle of a rigid body motion with about a fixed point should be axiatl vector,expound that one proctical rotative order may be exchanged with another, thereby demonstrate that the limited angle of a rigid body rotating about a fixed point is sure to be axial vector. |

| Keywords: | Motion with a fixed point Limited rotative angle Infinitesimal rotative angle vector |
