"And again similar to what we saw in Baghdad in 2003 when the United Nations was targeted the U.N.has become a target for terrorism.

So in other words, every time I merge the point that I kept emphasizing verbally there and that I'm only touching each number once, means that we have to account for the amount of time it takes to merge N which is going to be just N. Now, this is again one of these cyclical answers.

换言之，之前在做合并时,我不停地强调,对每个数字我只碰了一次，这就是说,我们要记录合并所花的时间量,也就是这里的,这又是一种循环性的答案。

And again, our energy is going to be the same where we again only depend on the n value.

同样的能量，和以前一样,因为它,只决定于n的值。

How do I rea-- replace the expression FOR t of n minus 1? Substitute it in again.

我们怎么来代替t这个表达式呢？,再来替换掉它，t等于。

So when we count, generally, again, we start from zero, we go to N minus 1.

当我们计数时，一般的，再次强调，我们从0开始，到N-1结束。

Again, we see that e is a function of n.

我们又一次看到，E是n的一个函数。

We'll get to discussing that, but what I want to point out here again is the fact that instead of just being dependent on n, the energy level is dependent on both n and l.

我们将要讨论它，但是我想指出的是事实上能级不只是与n有关,而是与n和l都有关系，而且n不再是。

Again, the reason for that is because the energy only depends on the n value here, it doesn't depend on l or on m.

因为，能量,只和n的值有关，与l和m的值无关。

And the last thing we can think about is how do we name this n h bond, and again, we just name it based on it symmetry.

最后我们要讨论的是,如何命名这个NH键，同样，我们基于它的对称性命名它。

So for sodium, again, we can write n e 3s1 and then 3 s 1.

对于钠，再一次,我们可以写Ne然后。

But there's something you'll note here also when I point out the case of the 2 s versus the 2 p, which is what I mentioned that I would be saying again and again, which is when we look at the hydrogen atom, the energy of all of the n equals 2 orbitals are exactly the same.

但是这里有一些事情你们也会注意到,当我指出2s和2p的情况，我之前提过,我会一次又一次的说，我们在观察氢原子的时候，2层轨道的所有n的能量,是完全相同的。

I was just finding very tunnel vision-like, the smallest elements at that moment in time which means I don't know anything about the other elements other than they are not the smallest and so no matter what with Selection Sort I had to repeat this again and again and again and if you do out the math it's roughly N squared steps in the worst case as well.

我只有一个狭窄的视野，只知道某时刻的最小元素,就意味着我并不知道其他元素的任何情况,只知道它们不是最小的,所以不管怎样，在选择排序中,我就得一遍一遍地重复选择过程,在最坏情况下,大概需要N的平方次比较。

So we know that we can relate to z effective to the actual energy level of each of those orbitals, and we can do that using this equation here where it's negative z effective squared r h over n squared, we're going to see that again and again.

我们知道我们可以将有效电荷量与,每个轨道的实际能级联系起来，我们可以使用方程去解它,乘以RH除以n的平方,它等于负的有效电荷量的平方,我们将会一次又一次的看到它。

I think most and you are familiar with the Aufbau or the building up principle, you probably have seen it quite a bit in high school, and this is the idea that we're filling up our energy states, again, which depend on both n and l, one electron at a time starting with that lowest energy and then working our way up into higher and higher orbitals.

我认为你们大多数熟悉奥弗堡,或者构建原理，你们可能,在高中见过它，又一次,这是我们填充能级的观点，与n和l有关，一个电子每次从,最低的能级开始,然后以我们的方式上升到,更高更高的轨道。
