| 摘 要： | 用二参方程φ=Z/ri/Z^＊/rc计算了Lewis酸软硬的标度，参数Z/ri与离子势有关，Z^＊/rc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．

| Abstract: | 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. |
