so we're going to use this concept of the path to go from the initial point to the end point.

在处理状态函数时,路径的选取。

dU=CvdT So du is still going to be equal to Cv dT, and we're still going to be able to use the first law, all these things don't matter where the path is.

于是，第一定律也依旧成立，这些关系都与路径无关。

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

If I look at different points in my container during that path, I'm going to have to use a different value of pressure or different value of temperature That's not an equilibrium state, and that process turns out then to be an irreversible process.

如果我要研究在路径中容器里的,不同的点，我就得在容器里不同的点上使用,不同的压强值,或不同的温度值,实际上这不是个平衡态，这个过程是,不可逆过程。
