摘　　要：利用诱导效应指数Ｉ，建立了计算一些ＣＨ３－Ｘ的键裂能的方法，并计算了一些甲基衍生物ＣＨ３－Ｘ的键裂能，其平均偏差为１．９３ｋＪ·ｍｏｌ－１。同时，推导出由ＤＨＯｍ（ＨＸ）和Ｉ计算烷基衍生物的键裂能的方法。２３个可比较值的平均偏差为２．６８ｋＪ·ｍｏｌ－１。By use of the inductive effect index I, the formula for calculating some bond dissociation energies of CH 3-X is built up, and some bond dissociation energies of methyl derivatives CH 3-X are calculated, its average deviation is 1.93 kJ·mol -1 . meanwhile, the formula for calculating the bond dissociation energies of alkyl derivatives from DH O m (HX) and I is derived, the 23 available average deviations are 2.68 kJ·mol -1 .
