They're very deep and held very tightly to the nucleus, so we can often lump them together and instead of writing them all out separately, 3s1 we can just write the equivalent noble gas that has that configuration.
它们非常深,被原子核吸得很紧,所以我们通常可以把它们混在一起,而不是把它们写开,我们可以写出氖然后3s1所以,或者任何的一个。

First we can do that by knowing the electron configuration, we can write it out just by going up the table here, up the energy levels.
首先我们知道了电子构型,我们可以从,能量最低处开始填。
It was nice because it wasn't just, "Okay, Let's write a story" or "Let's do a research about the animal" or "Let's do a poem about fish".
说它出色,因为孩子们这样做,不是因为老师要求“,或布置的任务“,或学校强制。
That is if I can write code that would solve all instances of smaller size strings, then what I just described isPalindrome will solve the larger size one.
然后我会描述如何处理大字符串,事实上这正是我所做的,我希望你能看看这边的这段代码,就是这个。
Let's try to do part of it in the head, so I can just write down the answer.
让我们先试试前面的一部分,我就直接写答案了
And I just want to write those because what I really want to get at is what's the efficiency of the whole thing?
我写出这些的原因,是我真正想得到的是,它的效率?
So just write it down, and I'll give you the numbers in just a second.
先写下来,我等会给你们答案
I just give you one of those, right, because you could write down the other one because you know the other complimentary sequence from base pairing?
我只写了一条链的序列,因为你们能够写出另一条,因为你们根据碱基配对,就能推测出互补链的序列
But it's amazing to read the letters and the language of slave traders when they write to each other, the complacency, the mixture of just pure racism on the one hand and just business language on the other.
当你阅读到那些奴隶商们,在往来的书信中所使用的言辞时,会令你非常震惊的,一面是混合在纯粹的种族歧视中的自满,另一面是那种完全商业化的措辞
So prices are determined as follows: prices depend on some parameters I'm just going to call a and b, and let me write the equation and then we'll see what it looks like.
价格由如下因素决定,价格取决于两个参数a和b,我们用方程写一下吧
Now as an aside, I'll admit this is a completely useless program, much like the first couple of ones we did because why would you write a program just to solve this?
说点题外话,我承认这是一个完全无用的程序,跟我们之前写的两个程序一样,我们为什么需要写个程序来解决这个数学运算呢?
So if we write out every term individually, what we end up with is essentially just the probability density for the first atom, then the probability density for the second atom, and then we have this last term here, and this is what ends up being the interference term.
如果我们把每一项都写出来,最后得到的就是,第一个原子的概率密度,然后是第二个原子的概率密度,然后是这最后一项,这就是干涉项。
b Let me just first write it down, the Van der Waals equation of state.
有两个参数,a和,如果a和b等于0的话。
V So this nR over V. And then, using the relation again, T we can just write this as p over T.
恒定温度下的dp/dT等于nR除以,再次利用状态方程,可以把它写成p除以。
The best suggestion is just to write it out completely for the neutral atom, and then you want to take an electron out of the highest orbital.
最好的办法是先写出它所对应,中性原子,然后再从,能量最高的轨道上拿走一个电子。
Probably I shouldn't have said it's a two-step process 'cause it's a three-step process to actually write and run it, and the third step is just going to be to run it.
也许我不应该说它是个两步完成的程序,准确来讲,应该是三步,前两步--写,第三步--运行。
And they are asked just to write the child's name.
他们只需写上孩子的名字。
So if you want to on an exam, you can just write this down quickly at the beginning and refer to it as you're filling up your electron configurations, but also if you look at the periodic table it's very clear as you try to fill it up that way that the same order comes out of that.
如果你们想要在考试中,你们要在开始时快速地把这个写下来,然后在填充电子构型,的时候参考它,但是如果你们看着周期表,它就非常清楚了当你们将它用从那产生的,同样的顺序来填充。
Now we can think about the fourth period, and the fourth period is where we start to run into some exceptions, so this is where things get a teeny bit more complicated, but you just need to remember the exceptions and then you should be OK, no matter what you're asked to write.
现在我们可以考虑第四周期,而且在第四周期,我们会遇上一些特例,所以事情有,一点复杂,但是你只需要记住,这些特例然后就没有问题了,无论你被要求写什么。
So it turns out a really nice shortcut on most systems, oops, is to say if you have a file called hello.c and you wanna turn it into a program called hello, well, make hello just write in the command makeHello and it will do all of that for you automatically and hand you a program called hello.
就是寻找一种能在大多数系统上运行的更快捷的方式,哇!,也就是说,你有一个hello,c的文件,你想把它变成一个名为hello的程序,那么只需要敲入命令,它就会自动为你生成,一个hello程序。
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。
