关于线性色谱的速率方程已有较深入的讨论。对于非线性色谱,一直存在着数学上的困难。1962年丁景群、朱葆琳曾用电模拟法作了讨论,现在更倾向于用计算机作数值解,但这些方法由于没有分析表达式,难於了解过程的机理。1982年张靓华尝试用特征线法与积分变换法讨论非线性色谱速率方程,由於没有考虑重要的纵 The rate equation for linear chromatography has been discussed in more depth. There have been mathematical difficulties with non-linear chromatography. In 1962, Ding Jingqun and Zhu Bolin had discussed the use of electricity simulation method, and now they are more inclined to use the computer for numerical solution. However, these methods are difficult to understand the process mechanism because they have no analysis expression. In 1982 Zhang Liang Hua try to use the characteristic line method and the integral transform method to discuss the nonlinear chromatographic rate equation, due to not consider the important vertical
