The first way is just to turn the crank on the math, and the second way is to do a little bit more imaginative about the process.

第一个方法就是纯数学推导,第二个方法我们将对,这个过程做一些物理图像的想象。

So if you're going to turn the crank v on the math correctly, you're going Cv to have to change this p into a V somehow.

所以如果哟啊正确地推导,我们需要把这个p变成,因为从数学上说这不是。
