Actually, what that would say, and we are going to see more about that so not very important right now, but what we would see is that for a close surface we would end up getting zero for the flux.
也就是这样了,现在来看点没那么重要的东西,对于一个封闭的曲面,如果通量为零。

Flux is going to be zero because nothing passes through the surface.
通量之所以为零,是因为根本没有东西通过曲面。

A rather systematic discussion on the methods of zeroflux section and surface flux were made in this paper. A locate flux method was put out as well and its experimental example was given.
