So, the divergence theorem gives us a way to compute the flux of a vector field for a closed surface.

散度定理为我们提供了一种，计算向量场通过闭曲面的通量的方法。

And that is indeed going to be the curl of F. in practice, if you have to compute the curl of a vector field, you know, don't try to remember this formula.

这就是F的旋度，在实际应用中，如果你必须计算一个向量场的旋度，不要尝试记忆这个公式。
