And to find the height of this thing, I need to know what actually the normal component of this vector is.

为了求出高度，需要知道这向量的垂直分量是多少。

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。

This means that they can be vector based and, therefore, you can provide a common component that can be used at a variety of resolutions.

这意味着它们可以是基于矢量的，因此，您可以提供一个公共的组件，在各种不同的地方使用它。
