例如，无论一个舞者多么想要跳离地板，然后开始旋转，角动量守恒定律绝对阻止这样的动作。
For example, no matter how much a dancer wishes to leap off the floor and then start turning, the law of conservation of angular momentum absolutely prevents such a movement.
这是角动量守恒的，立竿见影的效果。
That's immediate consequence of the conservation of angular momentum.
角动量守恒，惯量，平行轴原理。
