旋转体枢设于导引结构上，并沿导引结构回转。

Rotator is set on the structure and revolved along the guiding structure.

其滑移机制，可从旋转体不同圈层之间存在不同的动量矩得到解释。

The slipping mechanism can be explained with the different revolving moment of momentum of different revolving layers.

另外一个差异是男士在他们的想象中能够设想，改变，使一个物旋转体。

Another distinction is men are able to imagine, change, and rotate an object in their mind's eye.
