摘要
取代苯衍生物的标准生成焓与取代基的初级效应、次级效应和障碍点有关，本文建立了计算取代苯衍生物的新模型。
The standard enthalpies of formation of substituted benzene are related to the primary effect, secondary effect and the barrier point of the substituing groups.The work calculetes the gas phase standard enthalpies of formation of the compounds.The resulted values are well consistent with the experiment ones.
