摘要
由于常规GM(1,1)模型对反相HPLC冲化合物容量因子与流动相组成间非线性关 系的线性近似以及常规GM(1,1)模型建模方法所固有的缺点,使得常规GM(1,1)模型的预 测精度难以提高。本文用近代非线性回归分析法对建模方法作了改进,建立了具有更高精度 的GM(1,1)模型,并将其用于多环芳烃容量因子随流动相组成变化关系的建模,获得了满意 的结果。
The disadvantages of the traditional method for setting up grey model GM (1, 1) was pointed out, and an improved method was proposed by use of the modern nonlinear regression technique. Good results were got when the proposed method was used in the study on the relationship between capacity factors of polyaromatic hydrocarbons and the composition of the mobile phase.
