[The relationship between chromatographic retention value and grey model parameters].
The relationship between development parameter a, grey action variable u in the grey model GM(1,1) and parameters A,B which express the relation of k' and phi, that is, 1nk' = A + B phi have been studied. The functions of these two kinds of parameters which are a = -B lambda and u = B lambda eA[(1 - e-B lambda)(-1) - 1] are given. Therefore, it can predict the position of peaks and the possibility of separating the components in different mixtures. It verifies the experimental data, and gives out a proper method to amend equations. The results show that the function is fit for not only the research of chromatographic parameters of explosives but also the prediction of A,B values of other compounds.
