You just change volume to pressure and basically you're looking at enthalpy under a constant -- anything that's done at a constant volume path with energy, there's the same thing happening under constant pressure path for enthalpy.

可以看到这就是把体积换成了压强,一般我们都是在一种恒定状态下,考虑焓的，任何在恒容条件下,能伴随能量变化的东西，也在恒压条件下伴随焓同样地变化,所以你可以经常。

A progress bar is not supposed to print one hundred lines just to update its status; generally we like to see a little animation.

一个进度条不应该是打印100行,只是更新它的状态，一般地，我们,想看到一点生机。
