想要得到在恒压状态下的偏H偏，和在恒温状态下的偏H偏,好的，这是两个我们，在这里想要得到的东西。

OK, these are the two things were trying to get here.

It's constant pressure. OK, so now, last time you looked at the Joule expansion to teach you how to relate derivatives like du/dV.

这是恒压的，好，上节课你们,学习了焦耳定律,以及怎样进行导数间的变换。

It is taking place inside this thing, and it's a constant pressure, and we'll do it reversibly, right. So that's what we've got.

它是绝热的，在这个内反应,是在恒压下，它是可逆的，对吧？

OK, so this, what I've sketched here would be a constant pressure calorimeter. There's a reaction.

好，我画的就是一个恒压量热计,其中进行一个反应。
