本质上就是由于，未配对电子配对导致的成键。

Essentially what you have is bonds resulting from the pairing of unpaired electrons.

在前面一节，我讨论了价键法&电子配对理论。

In the preceding section we discussed the valence bond ( vb) or electron-pair theory of bonding.

本文应用平均场近似讨论了对角无序对局域电子配对系统的上临界磁场的影响。

The effect of diagonal disorder on the upper critical field of the local electron pair system is studied in the framework of the mean field approximation.

So, if we hybridize just these three orbitals, what we're going to end up with is our s p 2 hybrid orbitals.

我们会看到现在有3个未配对的电子，可以成键。

So, electron promotion does not happen in terms of nitrogen, because it would not increased our number of unpaired electrons.

这里对于氮原子不会有电子激发，因为这不会增加,未配对电子的数目。

And again, we have the pairing of the unpaired electrons, and we have two orbitals coming together.

同样，我们有未配对电子的配对，我们有两个轨道结合。
