If you want a more technical term for that , and you'll remember this from economics 115 can lead to outcomes that are "Inefficient," that are "Pareto inefficient," But "Suck" Will do for today.
要是想说的更专业店,记不记得在经济学115里面说的,会导致“不充分的”结果,即"帕雷托效率",但我们今天说"糟糕"就可以了
if you don't want to use that, you can also derive it as we did every time, it should intuitively make sense how we got there. But the exams are pretty short, so we don't want you doing that every time, so we'll save the 2 minutes and give you the equations directly, but it's still important to know how to use them.
吸收的和发射的,如果你不想用公式,你也可以每次都向我们这样推导它,很直观的就能得到结果,但考试时间很短,我们不希望你们每次都推导,所以我们会直告诉你,让你节省2分钟,但知道如何应用它十分重要。
All right. We've got a big majority, and both are logical ways of thinking, but it turns out that the majority is correct, which is not always the case, but the electron is not ejected in this case.
好,大多数人都这么认为,这两种看法都是合乎逻辑的,但结果是大多数人是对的,这种情况不经常发生,但是电子在这种情况下,确实不会被逐出。
I think it depends on whether the list is odd or even in length. Actually, that's probably not true. With one, it'll probably always get it down there, but if I've made it just equal to two I might have lost.
是奇数还是偶数,事实上,这是不正确的,如果最后剩下一个,那可能得到了结果,如果剩下两个,可能错了,所以,首先我们要格外。

So they'd much rather just stay the way they are and not have another electron come on, and it turns out that halogens have the highest electron affinities.
所以它们更愿意保持在原来的状态,不愿意再增加一个电子,结果卤族元素具有最高的电子亲和能。
So you can see that we're starting to have a very complicated equation, and it turns out that it's mathematically impossible to even solve the exact Schrodinger equation as we move up to higher numbers of electrons.
所有你们可以看到我们得到了,一个非常复杂的方程,结果是它在数学上是,不可能解出确定的,薛定谔方程,当我们考虑更高的电子数目的时候。
Second thing we've got to worry about is, what's a basic step? All right, if I bury a whole lot of computation inside of something, I can say, wow, this program, you know, runs in one step. Unfortunately, that one step calls the Oracle at Delphi and gets an answer back. Maybe not quite what you want.
我们需要担心的第二件事情就是,什么该作为一个基本的步骤呢?,如果我把一大堆的计算过程放到里面,我可以说,噢,这个程序你知道的,一步就完成了,不幸的是,这一步可能要靠预言家才能得到答案,这可能跟你想要的结果不太相同吧。
And this is a little different from what happened ten or so years ago, but the so-called Y2K problem was essentially the result of programmers not really having the foresight to realize, "Maybe we shouldn't use so few bits or so few digits to represent a year because eventually this will be a problem."
这个跟10年前发生的事情有点不一样,那个所谓的“Y2K“问题,本质上的结果是,程序员没有真实地预见和认识到,“可能我们没必要用到这些位数或数字,来表示一年,但是最终这个将会,是个问题“
And I don't quite remember from reading or from class how big these things are, well, it turns out -- and this is sometimes useful, later on more likely than now -- but C has a size of operator that takes an argument in parenthesis and it will tell you how much space is used to store that particular data type.
我不太记得类中的这些类型,是多大的,嗯,结果是--这个在以后比现在,可能是更有用的--不过C语言中有个sizeof的操作符,其中括号里有一个参数,它会告诉我们,要存储一个类型的数据,需要占用多大空间。
