That's the z component of curl F.

这是旋度F的z分量。

That means the z component of n is going to be zero.

就是说n的z分量等于。

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。
