Let's have a little review of the career of the great poet Orpheus as we get it certainly in L'Allegro and Il Penseroso.
让我们看看伟大诗人俄耳甫斯的经历,这在《快乐的人》和《沉思的人》中都有所提及。
Like, it's harder to get around L.A. because you have to drive everywhere and I really don't like driving.
想要在洛杉矶游玩要比在纽约困难,因为无论去哪都要自己开车,而我确实不喜欢开车。
One is simply the city's initials,L.A.

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。
The address is u-s-a-l-e-a-r-n-s dot o-r-g.

So that means it's not possible, if we've made these stipulations in the first place, to have a case where l equals 1.
这说明我们之前的假设,l等于1不可能的。
One is simply the city's initials, L.A.

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。
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.

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
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。
This is a painter called Frans Hals, H-A-L-S.
这是画家法兰斯·霍斯的作品
L.A.'s not as exciting as New York, I guess. It's more suburban and residential than New York.
我认为洛杉矶没有纽约精彩,她更属于郊区,更适宜居住。
So, you should know that there's four radial nodes, right, we have 5 minus 1 minus l -- is there a question?
你们要记住这里有四个节点,对吧,5减去1减去l,有问题吗?
How many bonding electrons does c l have? All right. Let's see, we've got a mixed response here, it turns out it has two bonding electrons.
氯有多少成键电子?好,让我们来看看,大家的回答不太一致,结果应该是两个成键电子。
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。
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。
And when we talk about l it is a quantum number, so because it's a quantum number, we know that it can only have discreet values, it can't just be any value we want, it's very specific values.
当我们讲,l是一个量子数时,因为它是量子数,我们知道,它只能去分立的值,它不能取到所有的数,它取一些确定的数。
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。
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。
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。
New York is different. It's still diverse but not as diverse as L.A., I feel like.
纽约就不同了。纽约也很多元化,但和洛杉矶相比还差一些。
n l So negative e, which is sub n l, because it's a function of n and l in terms of quantum numbers.
也就是负的,E,下标是,因为它是一个,关于量子数,n,和,l,的函数。
So, it would be a good question to ask n why are we limited clearly there's this relationship between l and n, and we can't get any higher than n equals one.
那我们要问了,为什么我们被限制了,很明显,l和,有关系,为什么不能取到,n-1更大的值。
What was-- what's really bad about calling a list l 1?
为什么把一个数组,命名为l1很糟糕呢?
That's really it. Not much to do in L.A..
就是这样,在洛杉矶能做的事也就是这些。
So if we compare l increasing here, so a 3 s to a 3 p to a 3 d, what we find is that it's only in the s orbital that we have a significant probability of actually getting very close to the nucleus.
我们比较当l变大的时候,从3s到3p到3d,我们可以发现只有s轨道,有很大的概率,非常接近原子核。
In the Savings and Loan crisis it was a certain segment of the banking community--the S&L's that seemed to be in trouble but it didn't seem to be then a house of cards that could spread around the country and around the world.
在储贷危机中,只是银行机构中的,一个特定部分-储蓄和存款,陷入了困境,但是这似乎不是一个,能够延伸至整个国家,和整个世界的不切实际的无法实现的计划。
