pV=RT dT here because the pressure is constant, dV=RdT/p so dV is equal to R over p dT.
因为对1摩尔气体有，于是。
-
Remember, we don't do a one-to-one correlation, because p x and p y are some linear combination of the m plus 1 and m minus 1 orbital.
记住，我们不需要把它们一一对应，因为ｐｘ和ｐｙ轨道是,ｍ等于正负１轨道的线性组合。
-
If I do the following, and I say, I'm going to assign p 1 to be p 2.
现在我要去做一些改动，这是为了让大家,更好的理解这一点。
-
p Well, it's not just p dS/dV because there's some dS/dV at constant T.
它不是简单的,因为式子中还包含，恒定温度下的。
-
So we're going to have to revise the P-functioning or the end of P-functioning theory of death.
我们要修改人格功能,或者人格功能的完结代表死亡这一说法。
-
So total quantity demand is 1 -P where P is the lower of the two prices.
总需求量是1-P,而P是两个公司的价格中较低那个
-
I have two electrons now to occupy the p-orbitals.
如果P轨道有分布了两个电子。
-
So we can have, if we have the final quantum number m equal plus 1 or minus 1, we're dealing with a p x or a p y orbital.
所以如果我们有,磁量子数ｍ等于正负１,我们讨论的就是ｐｘ或者ｐｙ轨道。
-
And I can give a name to that, so c p 1 and c p 2 are both going to point to that.
为这个实例分配了空间，现在它是空的,实际上也不完全是空的。
-
is going to be just the opposite of 2px So if you said 2 p x the first time, 2py say 2 p y this time.
就和，我们开始说的那个,如果你第一次说，现在就是。
-
It's reversible, that means that p external, equals p. I'm doing it very slowly so that I'm always in equilibrium between the external pressure and the internal pressure so I can go back and forth.
我都可以不损失能量，而把过程逆向进行,整个过程中的,每一步都保持平衡,现在我们来分别。
-
T p V I've got three variables, T, p and V.
一共有三个变量：
-
As p goes to zero of p times v bar.
适用于任何气体。
-
py So you can either write 2 p x or 2 p y, whichever one you want is fine.
这是对的，你们可以把它写成2px或者，哪种都可以。
-
I going to come back in a second to how it actually does that, but it basically says, get me x value for p 1, get me the x value for p 2, compare them, just as you would normally.
是一个类的实例,我要去取的这个实例，所关联的x值，我稍后会讲讲实际上，这里是怎么实现的，但是基本上它的意思就是，给我p1的x值。
-
To just introduce a piece of jargon, we could call those the P abilities, P for person.
用专业术语来说,我们可以称那些能力为P能力,P代表人
