Now, if you stare long enough at that equation, you'll actually see that, yes, we know that it had to be like that. But, see, so these are useful ways of trying to guess what the graph looks like.

如果你认真考虑那个方程，你会发现这个事实，是的，我们知道它应该是这样，看到了吧，这些是猜测函数的图像的有用的方法。

For potential flows on any stream surface, the equation of the velocity graph is set up by tensor analysis, and thus it provides an analytic method for solving some special flow problems.

本文利用张量分析工具，对任意流面上的位势流，建立速度图方程，为解决一些特殊流动问题，提供一个分析方法。
