And the reason for this, and this is a very important point about the photoelectric effect, and the point here is that the electrons here are acting as particles, you can't just add those energies together.

这个现象的原因是，这是光电效应非常重要的一个论点,这个论点就是电子,在这里是粒子行为，你不能仅仅把这些能量加在一起。

And just to look ahead a little bit, you could easily imagine that I might want to not just put a statement in there, what the specs are, I might want to put some constraints. Some specific things to check for, to make sure that you're calling the code right.

这不仅是抽象的概念还有规范的概念，我们再往前看看,你可以简单的想象得到，我不仅仅是想在这里加一个声明,这些规范说明中我还想加一些约束，我们要注意一些特殊的事情。

So we can add three hydrogen atoms here, and fill in our other orbitals right here.

我们可以加三个氢原子到这里，填满其它的轨道。

Put an asterisk by this.

给这里加个星号

RT So it's delta u plus RT, we can say T1 is the n temperature we've used here, delta n of the gas.

所以它应该是ΔU加,我们可以在这里用T1，气体的Δ

It's the term you see up here. It should be also on that sheet, Tanakh, which is really the letter "t", "n" and "kh", and they've put little "a's" in there to make it easy to pronounce, because kh is hard to pronounce, so Tanach. Okay?

就是这个，这个词应该也在这张单子上，塔纳赫-Tanakh，这字母分别发t，n和kh？,他们在这里加了个a’s，让它变得容易发音？,因为kh这个音很难发出？

Take these two equations, put an equal sign between them, replace this PR throughout with X, I'm going to have one equation and one unknown and that even the math phobics in the audience did in high school.

在这两个方程中间加个等号,将这里的Pr换成X,就会得到一个等式和一个未知数,剩下的问题,大家高中的时候就该回做了吧

So let's add one more piece to this.

好那么让我们在这里加一点东西。

We can also talk about it in terms of if we want to solve, if we, for example, we want to find out what that initial energy was, we can just rearrange our equation, or we can look at this here where the initial energy is equal to kinetic energy plus the work function.

初始能量是多少，也可以,写成另一种形式,我们可以把方程变形,或者我们看这里,初始能量等于,动能加功函数。

So this first little piece of code right here says, ok you give me 2 points, I'll create another 1 of these lists and I'll simply take the x, sorry I shouldn't say x, I'm going to assume it's the x, the x-values are the two points, add them together, just right there, the y-values, add them together and return that list.

好，为了来认识到这一点,让我们来看一个简单的小例子，在你们的课堂手册上，你可以看到我写了一个小程序,它假设我得到了，这些点中的一些，我想对它们做一些操作，例如我想把它们加到一起，那么这里的第一小片，代码的意思是，好给我两个点，我会再创建一个数组。

That means starting at the first one, I'm going to do something to it. And what am I'm going to do? I'm going to take that character, convert it back into an integer, and add it into some digits. And I've done a little short hand here, which is I should have said some digits is equal to some digits plus this.

这意味着从第一个字符开始，我要对他们进行一些操作,我要去做什么呢？我要取得这个字符，然后把它转换为整数,然后加到某些数上面去,我在这里用了一些缩写,我本来应该写一个数字等于这个数字。

But there's an important thing going on here, if I in fact wanted to combine those into a string I should have told the machine to do that, and I can do that, by explicitly saying, take that, which is a number, then add it to that string.

但是这里有个很重要的事情，实际上想要把这些加到一个字符串里面去,我应该告诉计算机去做这个，我应该这么做，通过明确的输入，也就是把这个对象，一个数字，然后把它加到一个字符串里面去。
