The H-bond plays a very important role in chemistry, physics and biology.
氢键在化学、物理和生物等研究领域发挥着非常重要的作用。
-
The calculated results show that the regioselectivity of this reaction doesn't result from the energy barriers of relate reactions but the energy gap of the H-bond complexes.
结果表明，决定该反应区域选择性的主要因素不是反应的活化能，而是氢键复合物间的能量差异。

So we have h, then we can draw our bond as a line.
那么我们有氢，可以把我们的键画成一条线。

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。
