稳健灰色模型在色谱保留值研究中的应用

Application of Robust Grey Model in the Study on Chromatographic Retention

本文提出了具有稳健性的GM（1，1）灰色模型，并用此模型对8种多环芳烃化合物容量因子与流动相组成间的关系作了研究，建立了其间的稳健数学模型。结果表明，稳健GM（1，1）模型比常规GM（1，1）模型具有更好的抗干扰性能和受异常点影响小的优点，是一个值得推广的好方法。既丰富了灰色系统理论，又拓宽了灰色理论在分析化学中的应用范围。

The robimt grey model GM(1,1) has been proposed and used in the study on the relationship between the capacity factor in liquid chromatography and the composition of the mobile phase for 8 kinds of PAHs. The results show that, as compared with the normal GM (1, 1) model, the robust GM(1, 1 ) model has the advantages of better resistence against dis turbance and less deviation by the influence of outlier, so it is a kind of good method worth spreading. It is possible that the robust chemometrics technology may have practical use in analytical chemistry.
