摘　　要：定义了有效主量子数拓扑指数（ Ｎ） 和成键原子有效主量子数ｎ*．Ｎ对１３种Ｐ区氢化物实现唯一性有征，并与其酸性强度（ｐＫａ） 呈现高度相关性．Ｎ结构意义明确，计算方法简单，使用方便；而且预测结果令人满意， 优于文献方法．A topological index( N ) of effect principal quantun Number has been defined. N has not onlygood setectivity for 13 inorganic hydrides,but also excellent correlativity for its acidity( p Ka ). It has been demonstrated that N is clear in srtucture meaning, easy to compute and convenient in application. The estimating results by N are also satisfactory.

关 键 词：有效主量子数 拓扑指数 氢化物 酸性强度 N指数
