摘要
用特征线－差分方法模拟了扩散系数为10－4（cm2／sec）数量级的非理想非线性色谱过程，所得结果与其他方法[4－5]及实验结果作了比较，激波峰定位更加符合理论值及实验值，并讨论了扩散系数D与保留时间tR间的关系，与文献[1，4]一致。
The nonideal nonlinear (involved diffusion D = 0.0001 cm2/sec) chromatography is simulated using characteristics-difference method. The simulation results are compared with the experimeatal values and the results from other methods. the positions of shock wave are more coincident with the theoretical and experimental results. Furthermore,relationship between the diffuse coefficieat D and the retention time tR is also discussed in this paper, it shows good agr eement with the results from Refs. [1] and [4].
