So if you get these two guys together you get CvdT=-pdV Cv dT is minus p dV.
把它们联系,起来。
-
And our job is to find out what is the mathematical description of this path, this line in p-V's case that connects these two point.
我们的任务,就是找出，描述这条曲线的方程。

The D.P.J.won almost two-thirds of the seats in lower house elections last Sunday.

And it turns out that when you constructively have two p orbitals interfere, and when I say constructively, I mean they're both either positive or they're both the negative lobes, that's when you got bonding.
当两个ｐ轨道,相长干涉时，我说的相干相长，意思就是说它们要么都是,正的叶瓣要么都是负的叶瓣，这时就能成键。

So we have the eagle that represents freedom,". "We have the two P-51 aircraft, which is the aircraft the men flew later on in the war.

And I'll say this and then write it more carefully, where P is the lower of the two prices.
我先讲,待会再写下来,P是两个公司价格中较低的那个
-
And if it sees S-W-A-P, open parentheses, close parentheses, and it hopefully sees two ints inside of it, that's all it needs to do in order to finish compiling your code.
如果它看到了SWAP，左圆括号，右圆括号，它可能载里面看到两个int数，那是它所需要做的,用来完成代码的编译。
-
It's a particle of mass m and momentum p has this energy so you solve for the energy, you get two answers.
一个质量为m,动量为p的粒子,有这么大的能量,你解出能量,得到两个解
-
same point It says, if you give me two of these data objects, I'm going to call them p 1 and p 2.
的代码，What，does，it，say，to，do？,你可以看看它,它是用来做什么的呢？,它的意思是，如果你给我两个。
-
So according to P, the priests are to offer two such burnt offerings with pleasing-smelling odors to the Lord every day: one in the morning and one in the evening on a regular basis from the community.
因此根据P所记载，祭司每天都将这两种,散发愉悦气味的烧祭品供奉给上帝：,早晚各一次,定期在居民面前做。
-
I have two electrons now to occupy the p-orbitals.
如果P轨道有分布了两个电子。
-
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。
-
So it's, this is just the integral pdv And it's an ideal gas, isothermal, right.
从一点到二点的,的积分。，from，one，to，two，of，p，dV。,这是理想气体，恒温过程，好的。
-
sigma2sp It's going to be a sigma bond. So, we have sigma 2 s p, carbon 2 s p. So they're two s p bonds combining.
是sigma键，我们有，碳2sp。，所以它们是两个sp键结合。
-
So this is a little bit trickier to look at and see what it means, but essentially we have two hybrid orbitals, which are shown in blue here, and then we have one p orbital that's left alone that's going up and down on the page.
看这个图肯能会觉得比较诡异，但本质上，骂我们有两个杂化轨道，这里用蓝色表示，还有剩下一个p轨道,在图中上下方向上。
-
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。
-
So in s p 2 hybridization, instead of combining all four, we're just combining two of the p orbitals with the s orbital.
这样就能得到sp2杂化，在sp2杂化中，不是四个轨道结合。
-
% Some people, the next most popular answer with 5%, which is a nice low number, wanted to put two in the 2 p x before they moved on.
下一个更多的选择占了,是一个比较低的数字，想要将两个电子在移动之前放入2px轨道,记住在我们双倍填充之前。
-
So, our two glitches we see when we go from the 2 p, or from 2 s to start filling the 2 p, and then we also get another glitch when we've half-filled the 2 p, and now we're adding and having to double up in one of those p orbitals.
因此，我们的看到的两个小偏差，一个是在开始进入，2，p，轨道，或者说在填满，2，s，轨道之后,开始填，2，p，轨道的时候出现的，另一个则是在，2，p，轨道半满之后,开始继续加电子，使得其中一个，p，轨道上的。
-
So, if we think about this z bonding axis between the two carbon atoms, we can picture overlap of those s p hybrid orbitals, and then we can also picture bonding to hydrogen.
如果我们考虑,两个碳原子之间的z成键轴，我们可以画出sp杂化轨道的交叠，我们也可以画出和氢原子的成键。
-
Adiabatic q equal to zero. It's also delta H 0 which is zero. The two didn't necessarily follow because remember, delta H is dq so p is only true for a reversible constant pressure process.
在这个过程中ΔH等于,绝热的所以q等于0，而ΔH也等于,这两个也不一定有因果关系,因为，记住，ΔH等于dq只有在恒压。
-
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
-
And so now we can move on to thinking about p orbitals, we now have two ways to talk about p orbitals.
现在我们可以继续来讲ｐ轨道了，我们有两种办法来讨论ｐ轨道。
-
So again, looking at the shapes, now we're just combining two, we've got these two equal hybrid orbitals plus these 2 p orbitals here.
同样，我们看它的形状，现在我们仅仅结合两个轨道，我们得到这两个杂化轨道,和两个p轨道。
-
So, what we end up having is three of these pi -- 2 p y 2 p y bonds, we can have one between these two carbons here.
我们剩下的有三个π键-,2py2py键，在这两个碳原子之间会有一个。
-
You can see that we have two unpaired electrons in this molecule here one in the pi 2 p x star, and one in the pi 2 p y star orbital.
你们可以看到我们这个,分子力有两个未配对电子,一个在π2px星，一个在π2py星轨道。
-
And seeing that it's a 4 p has two nodes - let's just write this out since not everyone did get it correct.
因为有些同学没答对,我们还是写一下,如果我们讨论的是4p轨道。
-
Now we're going to start in with that pi 2 p orbitals, which gives us 1 each, and then two each in those, we'll go up to our sigma 2 p z orbital.
现在我们要填π2p轨道，每个1个，然后每个2个，我们我们填sigma2pz轨道。
-
So there's p v work and it's given by the integral minus p external dv or just the integral from one to two of dw.
我们知道对于pv系统来说,功w可以写成黑板上的两种不同形式。
