/2 You can have it equal to plus 1/2, and that's what we call spin up, 1/2 or you can have it equal to minus 1/2, which is what we call spin down.
它可能会等于，我们叫它自选朝上，或者它等于负，我们叫它自旋朝下。

But they had several other books that we now call the Apocrypha, such as Judith or Tobit or the 1 and 2 Maccabees.

Line 1 is creating what we'll call a variable.

-
So what we do is we pick an origin, call it zero, we put some markers there to measure distance, and we say this guy is sitting at 1,2,3,4,5.
我们现在选择一个原点,称其为零点,我们做一些标记来测量距离,这个点在五个单位长度的地方

I take V1 to V2 first, keeping the pressure constant at p1, then I take p1 to p2 keeping the volume constant V2 at V2. Let's call this path 1.

So, we being chemists, 1s we'll call that 1 s instead of 1, 0.
作为化学家，我们把1，0，0叫做。

So, in this program when we call this version of swap 1 and 2 do not end up here, right?
所以，在这个程序中，当我们调用这个swap版本1,和版本2，不是在这里结束，对不？

It's only got two things to do, except what it really says is, that the complexity of search 1 is the same as the complexity of b search, b search because that's the call it's doing.
它只有两件事要做,其实实际上是1,它的复杂度和b，search的复杂度是相同的，因为它调用了。
-
psi1 0 0 We can call that psi 1, 0, 0, is how we write it as a wave function.
我们可以叫它，这是我们作为波函数的形式写出它。
-
same point It says, if you give me two of these data objects, I'm going to call them p 1 and p 2.
的代码，What，does，it，say，to，do？,你可以看看它,它是用来做什么的呢？,它的意思是，如果你给我两个。

So path number 1 went from i, f let's call this path up here. went to f, and this is how much energy change there was.
从i出发，经过路径1到达，能量的变化是这么多。
-
And in the even case, I'd square, divide by half, call this again: in the odd case, I go b minus 1 and then multiply by a.
就直接求a的平方的二分之b次方，如果是奇数的话，就去求a的b-1次方乘以a，以此递归下去。
-
If you do that, let's call the particular time t*, then 10t*-10=0, or t* is 1 second.
这样一来,我们把这个时间记为t,所以10t*-10=0,即t*为1秒
-
Let's suppose, we'll start with the list, I'll call it l 1. This, by the way, is a really bad thing I just did.

If it has 1 s and 3 p's, we call it s p 3.
如果它有1个s和3个p，我们叫它sp3。
-
So what you'll see in problem set 0 or problem set 1 is that you'll soon have access to what we call the CS50 cloud which is a bunch of servers that live on campus and on which you will all have a username and password.
所以你在习题集0或习题集1上看到的,访问“CS50云“,就是一些校园服务器,你可以注册一个用户名和密码。
-
That's just the those-- let me use my pointer that's just these two lines here. I checked the value, and in one case, I'm changing the last to be mid minus 1, which is the case I'm in here and I just call again. All right?
来看看ppt，这里有两条线,我检查了值，在一种情况下,我把last指向了中点减一,就是这种情况,我们再来调用一下怎么样？
-
So what we're going to converge in on to, is the S1*, let's call it in this case, is equal to 1 plus B S2* and that S2* is equal to 1 plus B S1*.
交点的横坐标是S1,暂且这么叫吧,S1*=1+BS2*,而S2*=1+BS1

palindrome I'm going to call this palindrome 1.
我把它命名为。
-
So, using the terminology of chemists, which is a good thing to do, because in this course we are all chemists, we want to make sure that we're not using just the physical description of the numbers, but that we can correlate it to 1 0 0 what we understand as orbitals, and instead of 1, 0, 0, 1s we call this the 1 s orbital.
我们最好学会，利用这些化学术语，因为我们这课,就是关于化学的，我们,不仅要知道，这些数字,的物理描述，还要能把它,和我们知道的轨道联系起来，我们叫它。
-
Let's call x the thing I'm trying to find the square root of. Let's start at 1. Square it.

1 Similarly, if m is equal to either plus 1 or minus 1, py we would in turn call it the p y orbital, or the p x orbital.
类似的，如果m等于+1或，我们可以叫它，或者px轨道。
-
And when we describe this in terms of talking about chemistry terminology, we would call the first one the 1 s, and 1 is in parentheses because we're talking about the first electron there, and we would multiply it by the wave function for the second one, which is also 1 s, but now we are talking about that second electron.
当我们用化学术语来,描述它的时候，我们称第一个为“1s“,括号中的1是因为我们,在谈论第一个电子,而且我们会用它的波函数，乘以第二个,第二个也是“1s“,但是我们现在谈论的是,第二个电子。
