It is being written and redacted at a time when there is a king in Israel, there have been kings in Israel, and it is providing laws for the construction of an ideal monarchy.

它是在以色列有国王的时候写成并编辑的，以色列曾有过国王，它为建立君主理念提供了律法。

Now going from three to four right, so we have another isothermal process for an ideal gas, so I won't try to make you sing again so soon.

从第三点到第四点，这也是一个理想气体的,恒温过程，这次不用你们集体回答了。

All the supreme court justices would share our social values. And most importantly, our programs would work the first time we typed them. By now you may have noticed that we do not live in an ideal world.

符合我们的社会价值观,但是最重要的是，我们写好的程序，第一次就能顺利运行,如今你可能已经注意到了,我们生活的并不是一个理想的世界。

So again, if you do a calculation where you're close enough to the ideal gas and you need to design your, if you have an engineer designing something that's got a bunch of gases around, this is a useful thing to use.

要研究近似理想气体的表现时,这个方程非常有用,下面再来看一个，对我们来说最有意思的,实际气体状态方程：,范德瓦尔斯方程。

but right now you're going to have to take it for granted. So, if the Joule-Thomson coefficient is equal to zero, just like we wrote, du = Cv dT du = Cv dT for an ideal gas, we're going to dH = Cp dT have dH = Cp dT for an ideal gas as well.

但是现在请你们应该把它看成理所当然的,所以，如果焦耳-汤姆逊系数等于零,就像我们写的，对于理想气体,我们也可以得到对于理想气体。

This is only true for an ideal gas. Since it's true for an ideal gas, then we can go ahead and replace this with Cv, and then we have Cp=Cv+R Cp with Cv plus R, which is what we were after.

常犯的一个错误，这只对理想气体成立,因为对理想气体成立,所以我们可以继续，用Cv代替,这项，最后得到。

du/dV under constant temperature was equal to zero for an ideal gas. And by analogy, we expect the same thing to be true here, because enthalpy and energy have all this analogy going on here. So let's look at an ideal gas.

偏U偏V在恒温下等于零,可以类比，我们希望在这里也一样，因为焓和能量有很强的类比性，让我们看看理想气体,【理想气体】
