No, we can't. Because if l equals 1, we can not have m sub l equal negative 2, right, because the magnetic quantum number only goes from negative l to positive l here.
不行，因为如果ｌ等于１,ｍｌ的值不可能等于－２，对吧，因为磁量子数的值,这时只能从－１到１

It turns out there's a new function strlen S-T-R-L-E-N that you probably have not used yet called strlen, S-T-R-L-E-N, programmers early on and still like to be succinct but communicates sufficiently what they mean.
结果这里有个新的函数,你可能没有使用过，叫做，早期的和现在的程序员喜欢简洁地,但是能充分的传达他们的意思。

It's as if Milton places the beautiful poetry of Shakespeare into the mouth of this evil magician so as to dismiss all the more easily the easy, L'Allegro-mode of poetry that Shakespeare seems for Milton to embody.
这就好像弥尔顿把莎士比亚美丽的诗句,放进了邪恶魔术师的口中,所以可以更容易地反驳，好像莎士比亚把L’Allegro模式诗给弥尔顿去具体化。

So that's why we saw, for example, in the p orbitals we had one angular node in each p orbital, because l is equal to 1 there.
这就是为什么在ｐ轨道中,每个轨道节点数都是１,因为这里ｌ等于１．
-
l l So what you can do for a 1 s is just take 1 minus 1 and then l is equal to 0, so you have zero radial nodes.
它等于1减去,是等于0的，所以没有节点，这和我们看到的是相符的。
-
For an f orbital, what is the quantum number l equal to?
对于一个，f，轨道，它的角量子数，l，等于几？
-
l Stupid convention, but you have to do dash L and then the name of the library.

s We are back over to E as a function of n, l, m and s, only we got there through this other torturous route.
我们回到将E作为函数n，l和，只要我们解决了这个烦人的路径。
-
It says, right. If j is-- well it says until j is at the less than the length of l-- it says, if min value is bigger than the thing I'm looking at I'm going to do something, all right?
只要j比长度l小,如果MinVal比我要找到元素大，我就要做些什么了,我们来遍历？
-
For an angular node, we're just talking about what the l value is, so whatever l is equal to is equal to the number of angular nodes you have.
对于角向节点，我们其实就是在讨论l，的值是多少，因此不管，l，的值等于几,它就等于你所有的角向节点的数目。
-
And then if we think about 3 s, 0 we want to start with 3, we subtract 1, again l is equal to 0, so minus and we have two radial nodes.
我们从3开始，减去，同样的l等于，所以减去0，我们有两个节点，这应该。
-
So if we have a 3 d orbital, we're talking about n minus l minus 1, what is n equal to? What is l equal to?
如果我们有一个3d轨道，我们用ｎ减去ｌ减去１,ｎ等于多少？ｌ等于多少？
-
In contrast when we're looking at a p orbital, so any time l is equal to 1, and you look at angular part of the wave function here, what you see is the wave function either depends on theta or is dependent on both theta and phi.
相反当我们看ｐ轨道时，任何时候ｌ等于１,你们看它的角向波函数，你们可以看到它要么是和theta有关,要么是和theta和phi都有关。
-
And what I want to point out here is this angular dependence for the p orbitals for the l equals 1 orbital.
这里我要指出的是,ｌ等于１的ｐ轨道随角度的变化。
