It's not going to be zero this time because we have non zero heat exchange between the system and the environment, right.?

热力学量，但是现在让我们看一下,我们的特殊函数，这次它不会是零,因为系统与外界的热量交换并不是零，对吧？

But since these are all simply state functions and quantities, this is generally true.

但是因为这些量都是态函数或者量,所以这个结果是普遍成立的。

Now, before, of course, in the first part of the class u we started out looking at u H and then looking at H not as functions of S and V or S and p, but as functions of temperature, mostly.

现在，在本课的前一部分,我们首先讨论了,然后讨论了,这两个量并未写成S和V或者S和p的函数，而是写成了温度的函数。
