摘要
运用三阶精度的P.B.M方法,求得非线性多组分色谱方程组:(?)C/(?)x+(?)F(C)(?)t=0的数值解。它与理论分析基本一致,反映了非线性色谱产生间断,出现激波的基本特征。由数值解转化为图解,显示了非线性多组分色谱激波、简单波的形成和发展,组分分离的全过程。直观、生动地表现出非线性多组分色谱的基本特征。
In this paper, the numerical analysis of the nonlinear chromatographic equation.(?)C/(?)x+(?)F(C)/(?)t=0 is done the forming and developing of the shock and simple wave, andthe wholl process of the components separation are showed and the basis charaders of the nonlin-ear chromatography are presented in coloured graphs intuitatively and vividly.
