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。
So, we do an integral over a path, dT for the heat capacity along that path, dT.
因此,我们沿着路径做一个积分,热容。

The biggest thing for me on that path is I needed to draw something out and I needed to get it out of my head.
在我看来,这条路上最重要的莫过于,是需要描绘出一些东西,再把它们忘却。
"The point is, that what we are looking for is not just to continue on the same path, we want to leap into the future.

First one, when I write a piece of code, especially code that has branches in it, when I design test cases for that piece of code, I should try and have a specific test case for each possible path through the code.
第一点,当我们写代码的时候,尤其是一些含有分支语句的代码的时候,当我为这些代码,设计测试用例的时候,我应该为每一个可能的程序路径,都设计一个特别的用例。
But Immigration reform advocates maintain a legal path to citizenship for undocumented workers will help boost the U.S.economy.

So, therefore, we must take up, he suggests, an ascetic path,engaging only, as he says, in "those works" that are fit "for such men as come proud, open-eyed" and laughing to the tomb.
因此我们必须采取,如他所说,一条美学的道路,这些作品只适合于,对那些骄傲的、睁着眼笑嘻嘻“,走向坟墓的人。

Reverse transcriptase is a naturally occurring protein, it has a biological function in HIV, but we can use it for a technical logical function here by going backwards on the biological path from messenger RNA to DNA.
反转录酶是在自然环境中存在的蛋白质,它在HIV中发挥着生物功能,但在这里它可以发挥一个技术功能,让它用信使RNA反转录出DNA
"Countless, countless moments of awakening led me ultimately to the path of Islam, and within that, to the practice of Sufism, or Tasawuf,which for me is intricately united with Islam."

And what you'll find is that the maximum work out is obtain for a reversible path.
对于各种可能的中间路径,我们将发现,做功做多的是可逆路径。
"I mean,he hands over 80 percent of his low-enriched uranium: that means for the next 13 months he will not be able to go down that path, meaning that he will lose a lot of leverage with the West,"

So for an irreversible process, I wouldn't really be allowed to put a path there.
不可逆过程,是无法画出路径曲线来的。
So, let's calculate w1. The work for path one.
计算这两个过程中做的功。
The reason for inexact doesn't mean it's a crummy measurement, t means that it's path dependent, and so the value of this integral depends on how you get from one to two.
这是因为它是,与积分路径有关的,因此这里的积分值,取决于从一端到二端的,具体路径。
So if I take p times V to the gamma, anywhere on the path, it's going to be equal to the same relation This is going to be true for any point on the path.
结果都,将等于,初态点的,只要在这条路径上。
du du for path number 2.
关注。
If you have a real gas and you write du is Cv dT and your path is not a constant volume path, then you are making a mistake. But for an ideal gas, you can always write this. And this turns out to be very useful to remember.
对于真实气体,如果其变化过程,不是恒容的,du=Cv*dT就不成立,但对于理想气体,这条规则永远成立,这一点非常有用,请记住。
If it isn't, then I'm going to go back around the loop, and notice what happens. If I get all the way around the loop, that is, all the way through that FOR loop and I never find a path that takes me through here, then the last thing I'm going to do is return a pair or a tuple with a special simple number none twice.
如果没有,我会回到循环看看发生了什么,如果我运行了整个循环,也就是整个for循环,我仍没有找到符合条件的路径,那么我最后做的事情就是返回一对,或者一个数组的两次none值。
