"But the size and configuration of this facility is inconsistent with a peaceful program."
VOA: standard.2009.09.25
And we talked about a triad being a configuration of three pitches where you take the first, the third and the fifth.
三和弦是由三个音高配置成的,你们可选取第一,第三和第五个音。
And we can also write this in an even simpler form, which is what's called electron configuration, and this is just a shorthand notation for these electron wave functions.
而且我们也可以将它,写为一个更简单的形式,它叫做电子构型,这个仅仅是这些电子波函数的。
Milton's pushing here toward a fantasy of physical invulnerability imagining an alternative -- this is science fiction an alternative model of bodily configuration that would render impossible the all-too-easy quenching of the tender eyeballs.
弥尔顿在这幻想着人的身体可以刀枪不入,他在想象一个另类的-这只是科幻,他在想象一个另类的身体构造模型,这样脆弱的眼球,就不会轻易受到伤害。
It is in a standing wave configuration.
是个驻波结构。
Then something that you probably have a lot of experience with is talking about electron configuration and writing out the electron configuration.
然后有一些事情是,你们可能有较多经验,那就是讨论电子构型以及,写出它们。
These are all isoelectronic, they all have the same electron configuration. And we can also think about going back to atomic size for a second.
这些都是等电子的,它们都有相同的电子排布,而,我们还可以再回想一下原子尺寸的概念。
So that's a little bit of an introduction into electron configuration.
所以那是一点点关于,电子构型的入门。
This is ionic radii with a noble gas configuration.
这是稀有气体的离子半径。
So, Lewis structures are really a model for a way to think about what the valence electron configuration is, and as I said, it's not based on quantum mechanics, it's something that Lewis observed far, far before quantum mechanics were discovered.
路易斯结构实际上是一个用来考虑价,电子排布的模型,而就像我说的,它并不以量子力学为基础,而是路易斯在以前发现的,在量子力学出现很早前。
And resonance is the idea that sometimes one single Lewis structure does not adequately describe the electron configuration around a given molecule, so instead you need to draw two different Lewis structures to describe that more appropriately.
而所谓共振态,就是有时候一个路易斯结构不足以,完整描述一个给定分子的电子排布,因此这时你需要同时画出两个,不同的路易斯结构来描述它,这样会更恰当。
N 2 So any chemist should be able to just look at n 2 and know that it's a triple bond, but that's not something that we've learned how did to do yet, so let's go ahead and start a new topic that's going to allow us to have some sort of sense of what the valence electron configuration, which includes whether something's a single or double or a triple bond can be figured out for any given molecule.
任何一个化学家都应该能够仅仅通过看到2,就知道它有一个三键,但是我们还没学习如何做到这点,因此下面我们就开始进入一个新的主题,它将使我们能够有一定的认识,对于价电子的排布情况,包括可以对任何一个给定分子中的键是单键双键,还是三键作出判断。
