Flux looks quite different in the plane and in space because, in the plane, it is just another kind of line integral, while in space it is a surface integral. 平面中的通量和空间中的通量有很大区别，在平面中，通量仅仅是线积分的另一种形式，而在空间中，它表现为曲面积分。 - 2
And whether these line integrals or double integrals are representing work, flux, integral of a curve, whatever, the way that we actually compute them is the same. 不管是线积分或是二重积分，也不管它们表示的是功还是通量，计算它们的方法实际上是一样的。 - 3
What it says on each small flat piece — it says that the line integral along say, for example, this curve is equal to the flux of a curl through this tiny piece of surface. 它可以对任一个小平面使用-，比如说对于这条曲线的线积分，等于通过这个曲面的旋度通量。
