OK, so I don't have to, it's a great question, I don't have to create a second one for cmp.

但是参数的顺序是相反的，好，那么我就不必，这是个很不错的问题,我就不必再创建。

So, second ionization energy simply means you've already taken one electron out, now how much energy does it take for you to take a second electron out.

第二电离能简单地说就是,在你已经拿走一个电子以后，再拿走第二个电子,所需要消耗的能量。

That one's not so obvious. So let's think about this for a second. To sort a list in linear time, would say, I have to look at each element in the list at most a constant number of times.

所以让我们来思考一会,要在线性时间能排序，列表里每个元素最多被使用常数次,不一定是一次，对吧。

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。
