• So you see in the hybrid orbital we actually have a larger lobe on top where they constructively interfered.

    所以你们可以看到在杂化轨道里,我们上面,由很大的一叶相长干涉。

  • And it turns out that when you constructively have two p orbitals interfere, and when I say constructively, I mean they're both either positive or they're both the negative lobes, that's when you got bonding.

    当两个p轨道,相长干涉时,我说的相干相长,意思就是说它们要么都是,正的叶瓣要么都是负的叶瓣,这时就能成键。

  • The reason that there is increased electron density here is you can see that these two orbitals come together and constructively interfere.

    你们可以看到两个轨道,靠在一起相长叠加,这就是为什么中间的电子态密度增加了。

  • So we can actually constructively and destructively combine these waves, these atomic orbitals to make a hybrid.

    我们可以相长,和相消叠加这些波,这些原子轨道可以杂化。

  • The reason that we can talk about this is remember that we're talking about wave functions, we're talking about waves, so we can have constructive interference in which two different orbitals can constructively interfere, we can also have destructive interference.

    我们可以这么说的原因是,记住我们说的是波函数,我们说的是波函数,所以我们可以得到相长干涉,这是两个不同轨道会相长干涉,我们也有相消干涉。

  • But first, I just want to remind you when we're talking about molecular orbital theory, this is treating electrons as waves, so what we're actually able to do is either constructively or destructively combine atomic orbitals to form molecular orbitals.

    但首先,我要提醒你们,当我们讨论,分子轨道理论的时候,我们把电子看作是一种波,所以我们可以相长叠加,或者相消叠加这些原子轨道来组成分子轨道。

  • And what we end up forming is a molecular orbital, because as we bring these two atomic orbitals close together, the part between them, that wave function, constructively interferes such that in our molecular orbital, we actually have a lot of wave function in between the two nuclei.

    最后我们得到了分子轨道,因为当我们把这两个原子轨道放在一起的时候,它们之间的部分,波函数,相干相加,所以在分子轨道里,我们在两个原子核之间有很多波函数。

  • So you should remember that any time we combine 2 s orbitals, what we're going to find is if we constructively interfere those two orbitals, we're going to form a bonding orbital.

    你们要记住,任何时候我们组合两个2s轨道,我们会发现,如果我们把它们相长叠加,我们会得到一个成键轨道。

  • You can see if we combine the s with the top lobe of the p, they're going to constructively interfere because they have the same sign.

    你们会看到如果我们把s轨道和p轨道的上叶结合,它们是相长干涉,因为它们负号是相同的。

  • We should be approaching young people, encouraging them to engage, cross our religious boundaries and engage constructively with the same sort of sense of purpose that al-Qaeda recruits young people with a destructive divisive ideology.

    我们应该靠近青年人,鼓励他们参与这项事业,跨越宗教界线,鼓励他们具有建设性地参与其中,带着与基地组织招募拥有破坏性的,分裂的意识形态的青年人时有的目的感。
