"The point is, that what we are looking for is not just to continue on the same path, we want to leap into the future.

so we're going to use this concept of the path to go from the initial point to the end point.

在处理状态函数时,路径的选取。

So if I take p times V to the gamma, anywhere on the path, it's going to be equal to the same relation This is going to be true for any point on the path.

结果都，将等于，初态点的,只要在这条路径上。

If it was non-reversible, I would be allowed to put an initial point and a final point, but I wouldn't be allowed to put a path between them like this, connecting them together.

如果是不可逆过程，我可以画出过程的初态点,和末态点，但是我不能再像这样,画出连接这两个点的，路径曲线来。

The sum of path number 2 and path number 3 get me to the same place, so the energy change by going through this time path, this intermediate point here back all the way to final state should be the same the red path.

而经过路径2和3可以3,到达同样的末态，因此经过路径,2和3带来的能量的变化，与路径1带来的,能量变化相同。

So any point I pick on that path will be equal to p1, V1 to the gamma.

也就是说路径上面任取一个点,计算p，V^γ
