So, for example, down here I wrote that it was n 2 and that it was h 2, but when I re-wrote the molecules up here, you saw that it's an h h single bond where it's a nitrogen-nitrogen triple bond.

比如，在这下面我写的是氮分子2,而这个是氢分子，但我在上面把这些分子的形式改写了，大家可以看到,这是一个氢与氢之间的单键，含一个氮与氮之间的三键。

The bond characteristics and charge transfer in the V-N-vacancy complex are analyzed.

分析了V - N -空位复合体的成键特性和电荷转移情况。

Obvious changes of atomic natural charge happened to atoms C(1), H(11), O(28), O(29) and N(27). The bond lengths and bond angles related to these atoms were also varied greatly.

参与新键形成和旧键断裂原子C（1），H（11），O（28），O（29）和N（27）的原子自然电荷及与其相关的键长、键角有明显的变化。

So notice a difference in these structures, is this has an n h bond whereas this has an o h bond.

注意它们之间的有一点不同，那就是一个有氮氢键,而另一个有氧氢键。

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。

And the last thing we can think about is how do we name this n h bond, and again, we just name it based on it symmetry.

最后我们要讨论的是,如何命名这个NH键，同样，我们基于它的对称性命名它。
