Now Smiley had caught another frog and gave it to the man and said, "Now sit him next to Dan'l and I will give the word."

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?
There's also The L.A. Times, which you can get now online with no problem from the -you can read every day's newspaper.
洛杉矶时报也提过,你可以在网上轻松找到,你可以读到任何时间的报纸
And the last example that we're going to talk about is thionyl chloride, so it's s o c l 2. This is another good step forward, because now we actually have four different atoms in our molecule.
我们要讨论的最后一个例子,是氯化亚砜,就是硫,氧,氯,二,这又是一个进步,因为我们的分子中现在有四个不同的原子了。
And now someone else perhaps, why did I include this -l switch followed by "cs50" at the tail end?
现在有些人可能会问:,为什么我在用“cs50“结尾时,又在它之前,加了个“-l“命令?
All right? Now, I'll say L 2 equals L 1.
好,然后我新建个L2数组和L1相等。
So when we talk about p orbitals, it's similar to talking about s orbitals, and the difference lies, and now we have a different value for l, so l equals 1 for a p orbital, and we know if we have l equal 1, we can have three different total orbitals that have sub-shell of l equalling 1.
当我们考虑p轨道时,这和s轨道的情形和相似,不同之处在于l的值不一样,对于p轨道,l等于1,我们知道如果l等于1,我们有3个,不同的轨道。
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。
Now what do we get if we print l? MIT is gone.
再试试显示数组内容,MIT没了。
Now I'll print L 2. Kind of what you'd guess, but here's the interesting question: if I say L 1 is assigned 0, L 1 sub is assigned 4, I'll print L 1.
然后我将显示下L2的内容,你,们猜猜这个有趣的问题:,如果我将L1赋值为4的话,再去显示下L1,会怎么样呢?
