And we looked at the component of a vector field in the direction that was normal to the curve.

我们研究的是，向量场在曲线法向量方向的情况。

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。
