| 摘 要： | 用二参方程φ=XZ/ri^2 Z^＊/rc^2计算Lewis酸软硬的标度，参数Z／ri^2与静电力有关，Z^＊／rc^2与共价力有关．运用该式计算119种酸的软硬度值，结果与Pearson根据实验总结的分类结果一致.

| Abstract: | In this paper, a scale for the Lewis acid strength has been calculated from the dual parameter equation φ=XZ/ri^2 Z^＊/rc^2 One parameter,Z/ri^2, is related to electroslatic force, another parameter, Z^＊/rc^2,is relat-ed to covalent force. By this formula, hardness -softness of 119 acids is calculated. This result is identical with Pearson＇s experiment classification. |
