这是平均共价，它是极性共价。

This is pure covalency. This is polar covalency.

为什么要称它为极性共价呢？

And why did he call it polar covalency?

所以你看得出极性共价就是，趋向离子键的。

So you can see that polar covalency is a tendency towards ionic bonding.

Because this is a dipole, he chose the pole part of dipole to give us polar covalency.

这就是偶极，鲍林选择了偶极中“极“这一部分来,组成极性共价这个词向我们诠释。
