刘大壮等曾提出气相色谱中同系物的交点方程:式中V_g~0、T~0为同系物类别的特性常数,m与温度无关,取决于化合物和固定液性质的参数。对正烷烃,参数m与碳数n成直线关系:本文研究指出了参数m的物理含义及其计算。
Liu Dazhuang et al. Proposed the intersection equation of the homologues in gas chromatography: V_g ~ 0 and T ~ 0 are characteristic constants of homologues, and m is independent of temperature and depends on the parameters of the compounds and fixatives. For n-alkanes, the parameter m is linear with the carbon number n: The physical properties of the parameter m and their calculations are pointed out in this study.
