所以我们可以在这里不保留这个，而是代入理想气体方程。

V So we can, instead of having the volume of the gas here, we can use the ideal gas law.

工业上用理想气体方程对气体进行定量分析，通过调节气体的温度压力来控制物料的配比。

An ideal gas equation is used for quantitative analysis of gas in industrial production, then by adjusting gas temperature and pressure, it is possible to control mixing ratio of materials.

所以，从测量的到的状态方程的数据，或者从状态方程模型比如理想气体方程，范德·瓦尔斯方程或者其他状态方程，我们就可以知道。

So from measured equation of state data, or from a model like the ideal gas or the van der Waal's gas or another equation of state you know this.

Let's try it with a different equation of state, that isn't quite as simple as the ideal gas case.

考虑一个不同的状态方程，这状态方程不像理想气体状态方程那么简单。

So let's take our one model that we keep going back to Equation of state, and just see how it works.

我们回到经常使用的理想气体模型,或者说状态方程。

I know I only need 2, so I can relate dV dV to dp through the ideal gas law.

我只需要两个就够了，因此可以用,理想气体状态方程消去。
