1·There's a bond dissociation energy going from the lowest available level in each molecule to the dissociation limit where we pulled the atoms apart.

我们把每个分子从最低能量把原子拉开,所需要的能量,叫裂解键能。

2·In contrast, the dissociation energy of a bond for hydrogen, and molecular hydrogen is everywhere around us, we see 432 kilojoules per mole.

相反，氢分子在我们周围到处都是，一个氢分子的离解能，是432千焦每摩尔。

3·So what we can actually directly compare is the dissociation energy or the bond strength of nitrogen versus hydrogen.

因此实际上我们可以直接进行比较，对氮分子与氢分子的离解能，或键的强度。

4·So, there's actually another way to graph it where we can directly graph the dissociation energy or the bond strengths.

其实，还有另外一种画这个曲线的方式，可以直接画出离解能的大小，或者键的强度。

5·We have also explored the dependence of dissociation mechanism on charge distribution and potential energy curve of broken bond.

探讨了解离机理与分子的电荷分布和断裂键的势能曲线之间的关系。

6·Under the condition of phase difference given, the bond-length and dissociation energy calculated are quite consistent with the experimental values.

在特定相位条件下，由此计算出的键长和离解能与实际值相吻合。

7·So, another way to talk about dissociation energy is simply to call it bond strength, it's the same thing, they're equal to each other.

讨论离解能的另外一种方式，是直接称它为键的强度，它们是一样的，彼此相等。
