pV=RT p plus a over v bar squared times v bar minus b equals r t. All right if you take a equal to zero, these are the two parameters, a and b. If you take those two equal to zero you have p v is equal to r t.
我们就回到,也就是理想气体,状态方程,下面我们来看看,这个方程。

Were going to make it for a mole of gas, T1 so it's R times T1, V and then we'll have dV over V.
假设是有一摩尔气体，那么就是R乘以，然后有dv除以。

Now you have to know from elementary calculus that v times dv/dt is really d by dt of v square over 2.
根据初等微积分知识你们得知道,v乘以dv/dt其实就是d/2)/dt

D-A-V-I-D Well, if I've got a five-letter word like D-A-V-I-D, well, that's like five bytes and yet we only have the ability thus far in this class to return one thing at a time I can't return five bytes to you, but wait a minute, those bytes by nature of a computer are just stored in RAM.
好的，如果有5个字母的单词，如，那是5个字节,我们只能返回一个东西,而不能返回5个字节，等一下，这些字节被计算机本能地,存储在内存中。

I don't really care what key he's in 'cause I don't have absolute pitch, but I can find well, maybe it's a I,VI,IV,V,I chord progression or a I, I IV V I V,I progression or I,IV,V,I.
我也不需要知道他所用的调号，因为我不知道确切的音高，但是我能听出其中的和声，可能是一个，I，VI，IV，V，I级的和声进行，或者，是一个I，V，I的进行，或者。

So, in fact, as Thucydides tells us beautifully in Book V, when the two armies actually hit each other they have already made a slight turn to the right.
因此,事实上,像修西得底斯在第五册里优雅描述的那样,当两军真正开始接触时,他们已经略微向右转了
-
Normally I couldn't do that Vdp because this term would have p dV plus V dp, but we've specified the pressure is constant, so the dp part is zero.
一般情况下我不能这么写,因为这一项会包含pdV和，但是我们已经假定压强为常数，所以包含dp的部分等于零。
-
v We don't know what it is yet. In order to change this from a p to a V, you have to use the chain rule. So let's use the chain rule.
为了把这里的p变成,我们需要利用链式法则,好，让我们使用链式法则。
-
We want a relationship in p-V space, not in T-V space. So we're going to have to do something about that. But first, it turns out that now we have this R over Cv.
我们想要p-V空间中的结果，而不是T-V空间中的,因此需要做一些变换，先来看现在的关系，它跟R/Cv有关。
-
And so now we have this quantity, p times v bar, and the limit of p goes to zero is equal to a constant times the temperature.
不仅仅对氢气或氮气适用，在p趋于0的极限下,它适用于任何气体。
-
So if you're going to turn the crank v on the math correctly, you're going Cv to have to change this p into a V somehow.
所以如果哟啊正确地推导,我们需要把这个p变成,因为从数学上说这不是。
-
v dv We have minus V1, V2, nRT over V dV.
负的v1，v2，nRT除以。
-
In this case, V = /P. Have two quantities and the number of moles gives you another property. You don't need to know the volume. All you need to know is the pressure and temperature and the number of moles to get the volume.
以及气体的摩尔数,就可以得到第三个量,知道压强，温度和气体的,摩尔数就可以推导出气体的体积,这称为状态方程,它建立了状态函数之间的联系。
-
The ideal gas constant doesn't change, temperature doesn't change, and so v we just have minus nRT integral V1, V2, dV over V.
理想气体常数不变，温度也不变，因此,是负的nRT，积分从v1到v2，dv除以。
-
So you know your cycle, you know, you could have a whole complicated sequence on a p v diagram of steps going back.
因此，对某一的循环过程，可以在pV图上画出,一系列很复杂的小步骤。
-
V They do have the same temperature though.
不同，a，different，volume。,但是温度是一样的。
