So, the first obvious one is to take V1 to V2 first with p constant. So take this path here.

从初态到末态可以有无数种路径2,甚至像这样，我们只研究两种。

I start off, either I take this path and carry on, or I take that path and carry on, but each box, if you like, gets touched exactly once.

程序开始后，或者采取这条路径然后继续，或者采取那条路径然后继续，但是每个图形，如果你喜欢这么说的话。

I take V1 to V2 first, keeping the pressure constant at p1, then I take p1 to p2 keeping the volume constant V2 at V2. Let's call this path 1.

容易计算的路径，第一条路径，是首先保持压强不变,体积从V1压缩到。
