基于作者提出的诱导极性叠加原理 ,设计了包括与诱导极性叠加总量相关的能量项的烷烃异构体的标准生成焓估算的新方法.与前人方法比较 ,它具有较高的计算精度、较少的参数 ,各参数物理意义明确 ,而且理论上可以推广到含多种杂原子的衍生物的标准生成焓的计算. Based on the principle of induced polarization superimposition proposed by the author, a new method for estimating the standard formation enthalpies of alkane isomers including the energy terms related to the total amount of induced polar superposition is designed. Compared with the previous methods, it has a higher calculation Accuracy, less parameters, the physical meaning of each parameter is clear, and theoretically it can be extended to the calculation of the standard enthalpy of formation of derivatives containing many heteroatoms.
