不可逆过程，是无法画出路径曲线来的。

So for an irreversible process, I wouldn't really be allowed to put a path there.

要确保你绘制的形状是路径曲线而非形状图层(注意下图的黑头所示)。

Make sure you draw your shapes as paths instead of shape layers (see arrow).

I can do that because it's reversible, and I can get a functional form out.

画出路径就意味着过程是可逆的，下面我们来看这条曲线的函数形式。

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。
