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。

But you must understand, I'm sure you already understood the way, because I've been here, I've been around for some time in this earth, so by now you must re-know that I'm just a ordinary human being.

但你们要明白，我相信你们也已经了解，因为我一直以来都是如此，现在再次提醒你们——我只是一个普通人而已。
