8n + 2n ' + 2 m rule and the VSEPR model

8n+2n'+2m规则与价电子对互斥模型

On the basis of 8n + 2m rule , a simple method is proposed for deducing the bonding and geometric structure AB , molecules .

在8n+2m规则的基础上，提出了ABn型分子化学键和几何结构的一种简便方法。

The number of long operation steps of this algorithm is about 5N , whereas the number of long operation steps of Horowitz 's algorithm [ 1 ] is about 8N .

本算法的长操作步数约为5N，而Horowitz方法的长操作步数约为8N。
