这不是对真实向量作叉乘，但还是起作用的。

I mean it is not an cross-product of actual vectors but it works the same way.

希望你们在昨天的习题课上，练习了怎样计算叉乘。

Hopefully you got practice with cross products, and computing them, in recitation yesterday.

利用矢量运算中的内积算法和叉乘算法来推导有功功率和无功功率。

The inner product algorithm and cross multiply algorithm in the vector calculation are used to deduce active power and reactive power.
