摘　　要：用二参方程=rZiZr*c计算了Lewis酸软硬的标度,参数Zri与离子势有关,Zrc*与原子势有关.运用该式计算了119种酸的软硬度值,结果与Pearson根据实验总结的分类一致.同时能很好地将Lewis酸的软硬性与它的反应性或其它性质联系起来.In this paper, a scale for the Lewis acid strengths has been calculated from the dual parameter equation φ=Z/ri/Z^＊/rc One parameter,Z/ri,is ionic potential, Another parameter ,Z^＊/rc,is atomic potential. By this formula, hardness-softness of 119 acids is calculated. This result is identical with Pearson＇ s experiment classification, and the reactivity of the Lewis acid can contact with its property of hardness-softness by this formula.

关 键 词：LEWIS酸 软硬度 离子势 原子势
