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?
m And we saw l and m last day.
上节课我们也讲到了l和。
D.C.United won the first two M.L.S.championships.

STUDENT: PROFESSOR: Oh, I'm sorry. So it's n minus l minus 1.
学生:,教授:不好意思,这是n减去l减去1.
At 3.32 a.m., the time the deadly quake struck last April 6, a requiem was played in L'Aquila's central Piazza Duomo.

So I'm not even willing to use the L words in describing what it is we have." Right?
甚至不愿意,用爱来表达我们之间的关系?

Yesterday, on M.L. King Day, I had the privilege of being on at least four radio programs about this new book I have out called A Slave No More, some of them quite terrific.
昨天是马丁·路德·金的纪念日,我有幸被超过四家电台的问答节目邀请去,介绍我最新出版的一本书《无奴之国》,有些问题很有深度
In contrast, if we're taking the wave function and describing it in terms of n, l, m sub l, and now also, the spin, what are we describing here?
相反,如果我们考虑一个波函数,然后用n,l,m小标l,还有自旋,我们描述的是什么?
n l m s Once we have chosen a certain mix of n, l, m and s, it is used once for that particular atom.
一旦我们选定了一组量子数,它就只能被一个固定原子所有。
So let's just think exactly what this means, and that means that if we take away function and we define it in terms of n, l and m sub l, what we're defining here is the complete description of an orbital.
让我们来考虑一下这是什么意思,这是说如果我们不考虑波函数,而是用n,l,m下标l来定义它,我们定义的,是一个轨道的完整描述。
And in order to label the various orbitals, as he called them, m he introduced two more quantum numbers, l and m.
为了给他所说的不同的轨道,标号,他又另外引进了两个量子数,l和。
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。
PROFESSOR: OK. We can have n 4, l 3, and then, sure, we can have m sub l equal negative 2 if l equals 3 What's the second value of l that we can have?
教授:嗯,我们有n4,l3,然后我们有ml等于-2,如果l等于3,l可以有的第二个值是多少?
Yup. So m sub l could equal 2 negative 2, negative 1, 0, 1 or 2.
嗯,m下标l可以等于,2,-1,0,1,或。
So we could have five values of m sub l.
所以它可以取5个值。
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。
So the allowed values for m sub l 0 are going to be negative l, all the way up to 0, l and then up to positive l.
所以m小标l的可能值,是从负l,一直到,然后到正。
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。
So finally, if we talk about our last example of when n is going to be equal 2, l -1 and then minus 1 for m.
最后我们要讲的,这个例子,是n等于2时,等于1,we,can,have,2,,1,for,l,而m等于。
So when we talk about a wave function squared, n l m he wave function, any one that we specify between n, l and m, at any position that we specify based on r, theta, and phi.
一个波函数,的平方时,对特定,特定位置r,theta,phi波函数,取平方,如果我们取平方。
l But now we need to talk about l and m as well. So now when we talk about a ground state in terms of wave function, we need to talk about the wave function of 1, 0, 0, and again, as a function of r, theta and phi.
但我们现在需要讨论,和m,现在当我们讨论,波函数的基态时,我们讨论的,是1,0,0的波函数,同样的,它也是r,theta和phi的函数。
So it's OK to not specify. I want to point out, pz whether you're in the p x, the p y, or the p z, unless a question specifically m asks you to specify the m sub l, which occasionally will happen, but if it doesn't happen you just write it like this.
我想指出的是,无论你在px,py或,除非一个问题特别地,让你指出l下面的,这种情况有时会发生,这样就可以了,但是如果它不做要求你们写成。
