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.
