And this spin magnetic quantum number we abbreviate as m sub s, so that's to differentiate from m sub l.
这个自旋磁量子数我们把它简写成ｍ下标ｓ,以和ｍ小标ｌ有所区分。
-
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？
-
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。
-
Didn't create a new list. The old l is still there but it's different than it used to be.
它改变了数组，而并没有新建一个数组,老数组l依旧存在。
-
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。
-
Some languages like English has a-- have a distinction between 'l' and 'r.' Other languages do not.
某些语言,如英语,在"l"和"r"之间是有差别的,其他语言则没有
-
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。
-
And is no longer that sole determining factor for energy, energy also depends both l on n and on l.
对于能量的,唯一决定性因素,它也依赖于n和。
-
l Stupid convention, but you have to do dash L and then the name of the library.
还是规定，必须先写,再跟上库的名称。
-
So I show that here, so in green, you have what's called a carboxcylic acid group, a c o o h, which gets converted by s o c l 2 to a c double bond o c l or an acid chloride.
我在这里用绿色表示，我们所说的羧酸族化合物，碳，氧，氧，氢，它被亚硫酰氯转化为,一个碳氧双键与碳氯单键组成的酰氯。
-
n*pi/L It turns out it is n pi over l.
结果是。
-
So let's think about lists. So if l is a list, l sort I can call something like s dot sort, l dot sort.
所以让我们想想链表，所以如果l是一个，链表我可以调用像是s，sort的函数。
-
And so, in this case, l could equal zero, 2 l could equal one or l could equal two.
所以这样的话，l可以等于，也可以等于1或。
-
R And we abbreviate that by calling it r, l by two quantum numbers, and an l as a function of little r, radius.
我们把它简称为，两个指定的量子数n和，它是半径小r的函数。
-
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。
-
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。
