Again, so as we don't get confused, normally we use S for strategy, but let's use P since they're prices.
为了避免混淆,通常我们用S表示策略,但是这次我们使用P,因为它代表价格
-
p So to jump from the 2 s to the 2 p, takes more energy than we can actually compensate with by increasing the pull from the nucleus.
也就是，从，2，s，跃迁到，消耗的能量超过了,由于原子核的引力增强而补偿的能量。
-
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。
-
Let's let p be Cartesian point, and we'll give it a couple of values. OK?
然后我们给它赋值，好不好？,发生了什么？
-
If a person's just a P-functioning body, how could it be that after the death ? of his body he's still around?
如果人只是作为人功能的肉体，他的肉体死后,他怎么还会活着？
-
So it is very hard to understand P's silence in this regard, if it stems entirely from the post-exilic, priestly circles.
很难理解P资源在这一方面的缄默，如果它来源于流放后时期，牧师圈子。
-
That's different when you have continuous values-- you don't have P because it's always zero.
和离散型随机变量的分布不同的是,连续型随机变量的分布中,某一点的概率值始终是零
-
So, if we hybridize just these three orbitals, what we're going to end up with is our s p 2 hybrid orbitals.
我们会看到现在有3个未配对的电子，可以成键。
-
sp3 PROFESSOR: OK, so it's 2 s p 3, and our second carbon is also 2 s p 3.
好的，是，第二个碳原子也是2sp3。
-
It's not constant pressure, because we have a delta p going on. It's not constant volume either.
也不是恒容，这个限制,是这个实验的限制。
-
So it's going to be a sigma bond, 1s and we have oxygen 2 s p 3 and hydrogen 1 s.
它是sigma键，我们有氧2sp3和氢。
-
So let's fill it out in this way, 2p keeping in mind that we're going to fill sigma out the pi 2 p's before the sigma.
让我们这样填上去，记住我们先填π,轨道再填。
-
The S&P 500 is 500 companies, who are major companies, so these tend to be mature companies and they tend to be in the dividend-paying stage.
标准普尔500指数包括500家大公司,这些一般都是成熟期的公司,他们一般都处于需要支付股利的阶段
-
p2 It's taking the name p 1 and it's changing its value to point to exactly what p 2 points to.
我要把p1赋值为1,这个操作有什么用呢？,这个操作把p1这个名字的,指针的值改变让它。
-
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。
-
We'll start with talking about the shape, just like we did with the s orbitals, and then move on to those radial probability distributions and compare the radial probability at different radius for p orbital versus an s orbital.
想我们对待ｓ轨道那样，我们先讨论ｐ轨道的形状，然后是径向概率密度分布,并且把ｓ轨道和ｐ轨道在,不同半径处的径向概率做一个比较。
