摘要 以量子化学方法在密度泛函B3LYP/631G(d)水平上计算得到了多氯代二苯骈呋喃系列化合物(PC—DF)分子的结构参数:最高占据轨道能(EHOMO)、最低空轨道能(ELUMO)、最正原子净电荷(q^+)、最负原子净电荷(q^-)、分子偶极矩(μ)、极化率(a)、分子平均体积(Vm)、恒容热容(Cv).采用误差反向传播(BP)算法的人工神经网络,建立了EHOMO、ELUMO、q^+、q^-、μ、α、Vm、Cv与PCDF色谱保留指数之间关系的模型,检测样本的预报值与实验值相对误差范围为-1.66%~2.39%,平均相对误差为0.31%,达到了很好的预测效果. The structure parameters EHOMO, ELUMO, q+ , q- , μ, a, Vm, Cve of polychlorinated dibenzofurans (PCDF) were calculated at B3LYP/6-31G(d) level. Using error back-propaga- tion(BP) algorithm artificial neural network(ANN), the relationship between EHOMo,ELuMO, q+ ,q ,μ,a,Vm ,Cv and chromatographic retention indexes of PCDF was established. The rela- tive error between predicted value and experimental value is in the range from --1. 66% to 2.39% with the average relative error of 0.31%.
