Which is the Gibbs phase rule, right?

这就是吉布斯相率，对吗？

Where, let me write down what the Gibbs phase rule is first.

首先我们写出吉布斯相律是什么。

So the first thing is for us to prove Gibbs' phase rule.

第一件事是证明吉布斯相率。

From the derivation of the Gibbs phase rule. its expression is studied.

本文从相律推导出发，考察了如何正确表达相律。

So next time, then, what we'll do is we'll start by deriving the Gibbs phase rule.

下一次我们要做的，就是推导吉布斯相律。
