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。
Remember, the divergence of a vector field What do these two theorems say?
向量场，的散度，这两个定理说了什么呢？
I'm going to prove that the flux of a vector field that has only a z component is actually equal to the triple integral of, RzdV well, the divergence of this is just R sub z dV.
我将要证明，一个只有z分量的向量场的通量,等于一个三重积分，其中被积表达式为。
So, if the gradient of a function is a vector, the divergence of a vector field is a function.
如果说函数的梯度是向量，那么向量场的散度就是函数。
OK, so you take the divergence of a vector field.
取一个向量场的散度。
The results are as follows:the convergence field of wet Q-vector divergence tilts northwards with height;
结果表明：湿Q矢量散度辐合场随高度向北倾斜；
