分区的工作方式是对键计算散列码。

The way partitions really work is that a hash code is calculated on the key.

数据库服务器不会在特定的哈希bucket中对键进行分类。

The database server does not sort keys in a particular hash bucket.

另外一点就是键长，我们对键的长度也感兴趣，也就是两个原子核之间的距离。

And we can also talk about the bond length, so we might be interested in what the bond length is, what the distance between these two nuclei are.

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。

Well, if this bond has completely identically equal sharing of electrons, then this bond will be nonpolar.

如果一根键连的两个原子,对键上的电子吸引程度是完全等价的，那么这根键是非极性的。

And if we put that in our bond here, we have 1, 2, 3 bonds, plus we have one lone pair left over.

如果我们把它们放到键里，我们有1，2，3个键，还剩下一对孤对在这里。
