Now, I know that you guys are not necessarily fond of computing flux of vector fieldS for surfaces so maybe you don't really see the point.

好吧，我知道你们其实不喜欢，计算一个向量场中曲面的通量，所以你们可能不知道我为什么要这么做。

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。

Maxwell's equations conserve certain properties-the magnetic field intensity, the electric displacement field and the Poynting vector that describes the electric flux of an electromagnetic field.

麦克斯韦方程中有某些特性是恒定不变的——磁场强度、电位移场以及描述电磁场电通量的坡印廷矢量。
