So it's great. Once you have demonstrated, once you have proven that this parallel axis theorem works, then, of course, you can always use it to your advantage.

很了不起啊，一旦你们证出来了，一旦你们证明了,这个平行轴定理可行，当然，你们可以一直,为自己的便利利用它。

Again, we have to use now the parallel axis theorem.

现在我们要用，平行移轴定理。

And now there is a theorem which I will not prove, but it's very easy to prove, and that is called the parallel axis theorem.

这个公式，我不会再验证了，但它很容易证明，它称为，平行轴定理。
