| 摘 要： | 通过引入转动张量来描述刚体的定点转动,避免了在用角位移描述刚体定点转动时所遇到的问题,即角位移在它是有限大小和无限小时属性发生了变化.验证了对于刚体定点无限小转动,可以分别采用角位移矢量和转动张量描述,两者是等价的.

| Abstract: | This paper describes a rigid body motion with a fixed point by rotated tensor and avoids the meted problem that when one describes a rigid body motion with a fixed point by angular displacement,namely,the attribute of it is different for finite and infinitesimal sizes.We also verify that both the angular displacement vector and rotated tensor can describe respectively the motion of an infinitesimal rigid body rotation with a fixed point.Both are equivalent. |
