-
And we find the same thing for these two atoms here, it's not actually a double bond, it's somewhere between a single bond and a double bond.
而且我们发现这两个原子的情况是一样的，它其实不是一个双键，而是介于单键与双键之间的。
-
We would predict to see a single bond between lithium, and it turns out that's what we see.
我们可以预测在锂中会看到一个单键，而实际上确实是这样的。
-
So if we look at its length, it's actually shorter than a single bond, but longer than a double bond.
因此如果我们看它的键长的话，它实际上比单键更短，却比双键更长。
-
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。
-
So, if we talked about a nitrogen-nitrogen single versus double versus triple bond, the triple bond will be the shortest and it will be the strongest.
因此，如果我们讨论的是氮与氮之间的单键,双键与三键，那么三键应该是其中最短的一个，同时也是最强的一个。
