If you end up with a dx, dy, dz in the surface integral, something is seriously wrong.
如果在这个曲面积分中是以dx,dy,dz结尾的，则表明出现了很大的问题。
Well, now we have a relation between dx and dz.
从而我们就可以得到dx和dz的关系。
Namely, let's say that you have a function maybe of three variables, x, y, z, df = fxdx+fydy +fzdz then you would write df equals f sub x dx plus f sub y dy plus f sub z dz.
即是说，如果你有一个,含自变量，x，y，z的函数，那么。
