摘要: 采用半经验量子化学PM3的方法计算出130个有机化合物的描述符,用启发式方法分别对化合物在全二维气相色谱的3支色谱柱上的保留值建立了相应的定量结构-保留相关模型,并对模型进行了检验。所建模型呈现较好的线性,相关系数的平方(R2)均大于0.88,标准偏差(S)均小于0.105,留一法交互检验的相关系数的平方(R2cv)与所建模型的R2相当,说明模型具有良好的稳定性。化合物的预测结果显示所建模型有较准确的预测能力。

Abstract: The descriptors of organic compounds were calculated by means of semi-empirical PM3 method and the quantitative structure-retention relationship model of organic compounds on three columns of comprehensive two-dimensional gas chromatography were set by heuristic method. The good stability and predictive power of the multi-linear model were tested and the results showed the model had good linear relationships with all squared correlation coefficients more than 0.88 and each standard deviation less than 0.105. The leave-one-out cross-validated squared correlation coefficients were corresponding with the squared correlation coefficients from the model.
