"We are coordinating with each other. We are sharing intelligence,".
VOA: standard.2009.07.04
We are committed to sharing intimacy, to being friends forever but physical attraction is not part of the equation here.
我们亲密无间,一生一世,有没有激情体验无关痛痒。
And we can do the same thing with, well, we're going to do it with nitrogen in a minute, but this is a case where we have two atoms sharing electrons.
然后同样的,我们也可以很快的对氮气进行类似的处理,但是这是共用电子,的双原子例子。
So as we said when we first introduced covalent bonds, it's a sharing of electrons, but it's not always an equal sharing.
当我们刚开始介绍共价键的时候,我们说过电子是被共用的,但是共用却不一定是均等的。
Well, they would probably agree that we'd do some risk-sharing, right?
也许会达成共识,我们来分摊风险,对吧?
On the other hand, if we have a perfect covalence bond, we have identical equal sharing.
另一方面,如果我们有一个完美的共价键,有相同程度的电子共享。
So, we see is when we use the octet rule to look at fluorine molecule, we're combining two fluorine atoms, and what we end up with is an f f molecule where they're sharing two electrons, so making that covalent bond.
那么,我们看到把八隅体规则用到氟分子上,就是把两个氟原子组合起来,最终得到的氟分子中两个原子,共用一对电子,这就构成了共价键。
Well, on the one hand, we have ionic bonding where we have complete sharing.
好吧,一方面,离子键有完全的贡献。
But we know that just by this calculation, that we don't have equal sharing.
但是如果通过仅仅计算,我们得不到相同程度的电子共享。
And to measure the intensity of unequal sharing, we take the difference in electronegativity, which I am going to use the Greek symbol chi for.
要度量非平均的程度,我们考虑电负性的差异,我要用希腊语第22个字母chi来表示电负性。
So, that means we have to devise ways of sharing with people that we've never met, that we don't care about--I mean, maybe we care about everybody, but we don't have any particular emotional ties to them-- and they're very different people.
那意味着我们必须设计一些方法,使我们与素未谋面的,并不亲近的人们一同分摊风险,也许我们非常博爱,但未必对所有人都会怀有特殊情感-,分摊者应该是与我们非常不同的人。
