And if we experimentally know z what the ionization energy is, we actually have a way to find out what the z effective will be equal to.
我们实际上就有了一个办法,去找出有效的，等于多少,我们可以使用这里的方程。

Let's look at a few situations, where we can use these pattern.
下面我们来看一些可以使用这些句型的语境。

So now that we begin to have this ability to express strings in memory, to understand what they are, we can start to apply actually real-world algorithms to them.
现在我们开始用这个技能来在内存中表达字符串,来理解它们是什么，我们可以开始,我们可以对其使用实际的，现实生活中的算法。

I think so. But video phone has been very hard to achieve. It's either been to be expensive, or too crowded, or can we use the internet to finally introduce video phone and this is different from video on-demand.
我也这么认为，但视频电话要成功很困难,它要么很贵，要么很拥堵，或者我们是否可以使用互联网引入视频电话,这与随需视频是不同的。

So, I brought up this idea, "What if we could just use SMS? You could send what you're doing. It will go out in real time to all the people who are interested in hearing it. And then, it would be archived on the Web. You could also enter it from the Web and it would be device-agnostic.
所以我提出了这样的想法，如果我们只使用短信息会怎么样？,你可以发送你正在做的事，它会立即,让每个有兴趣听的人都看到，接着，它会在网上存档，你还能再网上读到它,而不需要设备支持。

Well, we can't guarantee with UV light we'll have enough energy to eject every single electron, so that's why when we use x-rays, they're higher energy, you can pretty much be guaranteed we're going to eject all of those electrons there.
好，我们不能保证紫外光有足够的能量,激发出每一个电子，所以我们要使用，X，射线，它的能量更高，你可以非常确定,我们可以激发出其中所有的电子。

Arthroscopic surgery in one sense is a fancy example of that, a way of looking inside a joint to see what's happening inside while the person is alive and without hurting them.
关节镜手术就是一个极佳的例子,使用该技术我们可以一窥关节内部,而不影响病人的生命,也不会过分痛苦

We can use this type of a question in many situations.
我们可以在许多语境下使用这一问句。
-
- The fact that I've called it X, is really just a programming -- it's a feature of the programming language that I, the human, can now refer to it.
事实是我叫它为X，它实际上只是一个程序-,它是程序的一个特写，我们可以参考使用它。
-
I have no idea what's here at the moment so I'm just going to draw a question mark because that memory might have been used previously for some other purpose, but we know it's currently available to us so we have four bytes of memory.
我不知道在此刻这里是什么,所以我画一个问号，因为那块内存可能在之前,为其它的目的而使用过，但是我们知道它可以为我们所使用,这样我们就有4个字节的内存。
-
And what we can do is we can also use the Schrodinger equation to make these accurate predictions for any other atom that we want to talk about in the periodic table.
我们能做的是,我们可以使用,薛定谔方程去做一些,关于我们想要讨论的元素周期表,中任何一个原子的预测。

Now down here I can use that other piece of syntax we just saw.
到这里，我可以使用我们刚才看到的,其它的语法。
-
You can actually declare in C synonyms using special syntax that says, you know what, even though yes at the end of the day I'm implementing false as a 0 and true as a 1, I can abstract away from that detail and use words that are more intuitive to me like true and false.
实际上，你可以用C语言中的特定的语法,你们懂得，虽然到最后,我把0当成假，1当成真来看，我们也可以从这些细节中抽象出来,使用像“真““假“这样更直观的词。

As an aside, why are you able to use print F without writing out a prototype for it?
此外，为什么我们不用写printf的函数原型,而可以使用它呢？
-
So we know that we can relate to z effective to the actual energy level of each of those orbitals, and we can do that using this equation here where it's negative z effective squared r h over n squared, we're going to see that again and again.
我们知道我们可以将有效电荷量与,每个轨道的实际能级联系起来，我们可以使用方程去解它,乘以RH除以n的平方,它等于负的有效电荷量的平方,我们将会一次又一次的看到它。

And for those of you who want to pick up a more sophisticated text editor, we will point you in the direction soon of tools called Vim, or Vi, Emacs.
如果你们有谁想使用,更高级点的文本编辑器的话，我们可以给你们,一些指导：像Vim，或者Vi，Emacs编辑器。

You wouldn't be expected to be able to guess that this would happen, because using any kind of simple theory, we would, in fact, predict that this would not be the case, but what we find experimentally is that it's more stable to have half filled d orbital than to have a 4 s 2, and a 3 d 4.
你们不用预期有能力,猜出这个会发生，因为使用任一种简单的理论，我们事实上可以预测不会是那种情况，但是我们在实验中发现的,是半填充d轨道比,4s23d4更加稳定。

Indeed, swap in your printout there is just defined as now taking *a and *b and then it also uses the * later, but we'll come back to what the different uses of the * means, but for now I claim conceptually it just means swap has access to the locations of its parameters.
的确，在打印资料中的swap被定义为,携带*a和*b，之后它也是带*号的，但是我们将说明*的不同用法，现在，我断言swap可以,使用参数的地址。
