Ok, one last thing I want to show you before we start reviewing, so one question you might have about Stokes theorem is, how come we can choose whatever surface we want?

在开始复习之前，我想讲点东西，大家对Stokes定理可能有一个疑问，我们如何选择我们想要的曲面？

Here I will show you how I create a painted metal surface worn by time with paint chipping off, revealing older paintwork underneath.

我将要向大家介绍如何创建出一个饱经风霜的，油漆都退掉的金属表面。
