然而，这些过程都是自发进行的。

And yet, these things are all spontaneous processes.

这有一些自发进行的化学反应，这一个。

So here are some spontaneous chemical changes here's one.

OK, clearly we'd be much better off if we had some systematic quantitative way to tell whether something would happen spontaneously.

好，如果我们有一些系统定量的方法来判断,一个过程是否会自发进行,那就会更好了。

And it follows qualitatively from just your ordinary observations a bout the direction in which things go spontaneously, right.

定性地来说,就是你们日常生活中观察到,自发进行的物理现象,会有方向性。

And so what this gave us was a very, very useful general criterion for determining whether something happened spontaneously.

这个告诉我们的是一个,非常非常一般的判据,他能帮助我们判断一个过程是否自发进行。
