and the same for favour, they spell f-a-v-o-r, we put u in it,
同样地,对于发烧这个单词,他们拼写成f-a-v-o-r,我们要加一个u在里面,
When we talk about p orbitals the phase of the orbital becomes important once we talk about bonding, which hopefully you were happy to hear at the beginning of class we will get to soon.
对于p轨道,当我们讨论到成键时,轨道的相位就变得非常重要了,这个我们马上就要讲到了。
But we might then wonder, for every person who gets less than the average amount of life-- suppose we take the median, take the amount of life that's exactly, 50 percent of the people get more, 50 percent of the people get less.
但是接着我们可能会想,对于所有活得比平均寿命要短的人-,假设我们取中间数,相对于平均寿命,刚好五成的人活得更长,五成的人活得更短。
I shall always be a flower girl to Professor Higgins because he always treats me as a flower girl and always will," made into a better known movie, My Fair Lady.
对于Higgins教授来说,我永远是一个卖花女,因为他一直待我如卖花女,以后也会”,这出戏剧改编成电影《窈窕淑女》
In valence bond theory, the focus is on discussing the bonds, but it should look very familiar to you, because there's two types of bonds that we want to discuss here.
在价电子成键理论中,所关注的是讨论成键,但这对于你们来说应该很熟悉,因为这是我们要讨论的两种键。
For the sulfur, we start off with 6 valence electrons, minus 4 lone pair electrons, minus 2, taking in account our bonding electrons, so we end up with a formal charge of 0.
对于硫,我们从六个价电子开始,减去四个孤对电子,再减去二,算上我们的成键电子,因此最终我们有零个形式电荷。
/2 So this would mean the bond order is equal to 1/2, and in terms of valence electrons, how many bonding valence electrons do we have?
这意味着键序等于,对于价电子,有多少个成键价电子?
So for some you that are less interested in maybe the physical structure of an individual atom, now some more exciting material for you might be coming up if you like to think about how, instead, molecules behave, either within bonding, within themselves, or with other molecules, that's what we're going to be heading to in this next unit.
那么对于某些同学,你们或许不感兴趣,对于单个原子的物理结构,现在可能有令你感到兴奋的内容,要出现了,如果你更喜欢思考,分子的行为,或者是关于成键的,或者是关于它们本身的,又或者与其它分子之间的行为,这些将是我们下个单元要讲的内容。
If we think about bringing in those last two carbons, what you can see is that for every carbon, two of its hybrid orbitals are being used to bond to other carbons.
如果我们考虑引入最后两个碳原子,你会看到的是对于每个碳原子,其中的两个杂化轨道,和另外的碳原子成键。
So in terms of the carbon hydrogen bond, it's a sigma bond, - because we define it -- any time we are bonding to an atom, we have to keep redefining our bond axis to whatever two atoms we're talking about.
对于碳氢键,它是sigma键,因为我们定义它-,任何时候我们有原子成键,我们要重新定义键轴方向,为我们所讨论的两个原子方向。
So what I'm inclined to think with regard to this particular strand or this particular version of the argument is, the jury's still out.
所以我倾向于,认为,对于这个特殊的困境,或说成是,对这个特定版本的,论证,还无法下定论
So essentially, we have two ethene or ethylene molecules here to start with where these blue are our 2 s p 2 hybrid orbitals, so you can see that for each carbon atom, one is already used up binding to another carbon atom.
本质上,我们从两个乙烯分子开始,蓝色的是2sp2杂化轨道,你可以看到,对于每一个碳原子,其中一个已经用来和另外一个碳原子成键。
