摘要
根据灰色理论建立色谱保留值预测模型,可以为探讨混合多组分分离条件提供依据。灰色动态模型由GM(1,1)和灰数等维递补动态模型组成,应用于多环芳烃化合物容量因子与流动相组成间的关系研究。结果表明,灰数等维递补动态模型比常规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。灰色动态模型的提出为灰色理论应用色谱保留值的预测以及其它较复杂化学体系的研究提供了一种新方法。
Grey theory is fit for studying the chromatographic retention problems. The dynamic model of Grey System 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 polyaromatic hydrocarbons. The dynamic model of Grey System is composed of GM( 1,1) and the dynamic model with recursive compensation by grey numbers of identical dimensions. The results show that,as compared with the normal GM( 1,1) model, the dynamic model with recursive compensation by grey numbers of identical dimensions has the advantages of better resistence against disturbance and less deviation by the influence of outlier, so it is a kind of good method worth spreading.
