But it grows pretty rapidly, as n goes up, and I'm going to show you an example in a second.

解决问题需要的时间会急剧增长，一会儿我会让大家看个例子的,我想大家注意的还是。

It depends on n and k but obviously as n gets big, that one is going to be better.

但是很明显，当n取很大的值的时候,前者要比后者好。

If I look at something that goes as n squared, if this is the edge of the nucleus here and if this is r1, 4 it says when n goes to two the radius goes to four.

如果在原子核外侧,我们发现某一半径和n的平方成正比，也就是说当n为2时半径等于。

So it feels a little backward mentally perhaps, 1 but this is saying, "do this block of code as long as n is less than 1."

所以它感觉可能有点迟缓，但是它指明，“只要n小于,执行这段代码“

So if we're keeping n the same, we look and what we saw was that size actually decreases as we increase the value of l.

如果我们保持ｎ不变，我们看到随着ｌ值的,增大尺寸变小。

So, the optimal thing to do if you live in a world like this n is to get n as large possible and you can reduce the standard deviation of the portfolio very much and there's no cost in terms of expected return.

如果现实中也这样简单的话,那么你就尽量增大,这样就能让投资组合的标准差,就会大大降低,从预期收益率的角度来看,这样做的成本是零。

I mean, you'll play with it in great-- with great delight this semester, you will see that backslash N is the standard in any text file for creating what we know as new line characters.

我是指，这学期，你们会很高兴-,和它打交道，同时你们也会看到,在任何文本文件里，反斜杠n已经是,换行的代名词了。

And the complete description, as I said, n l m is from n l and m.

我说过完整的描述，需要。

n And these are known as anions. It has the n, which might conjure up negative, or anion and minus both have five letters.

这些就是负离子，有，能让我们想起，负，这个字，或者负离子和负号都是5个字母。

And note that as Z increases, as the proton number increases the radius decreases for a given n number.

并注意到当Z不断增加，对于一个给定的n，即当质子数增加的时候,半径的n值就减小了。

This backlash N, it's also a recurring theme and not just in C but in PHP, JavaScript, other languages as well.

还有反斜杠n，不仅C语言里有,在其他语言像PHP，JavaScript等都会碰到。

And when we talk about size, I'm again just going to say the stipulation we're not talking about an absolute classical concept here, but in general we're going to picture it being much further away from the nucleus as we move up in terms of n.

当我们说到尺寸时，我们只是说――,经典的绝对的概念，而是它大约,离原子核有多远。

The differences between those energy levels are becoming smaller and smaller as the n number rises.

那些能级间的差异,会随着n值的增加变得越来越小。

So this is not even thinking about the other electron shielding, just if we think of the fact, all we need to think about is that the effect of going to a further away n n as we go down the table.

到现在我们甚至还没有考虑,其它电子的屏蔽效果，即使我们要考虑这个因素，我们需要考虑也就是,沿着周期表的某一列往下走，距离会逐渐变远,将起最重要的作用，actually，dominates,这一结果所产生的影响。

That's why in the earlier models of the atom, they're not horrible to sometimes think about just each n value as a little ring around.

这就是为什么在早期原子模型中，人们没有感觉到把每一个，n，都想象成,一个绕核的小圆圈有什么不妥。

b The repulsive term goes as some constant lower case b divided by R to the n. N is not the quantum number.

这种斥力很想一个固定的小写字母,被R到n分开的话，N不是量子数。
