axial heat diffusion

Peclet number(Pe) and mixing time(tm) represent axial dispersion behavior and mixing behavior,respectively.

用混合时间表征混合特性,用Peclet操作准数表征轴向扩散特性。

Peclet number(Pe) is used to represent the axial dispersion.

用Pec let操作准数表征轴向扩散特性。

The axial dispersion in chromatography models was discussed with vector method and the effect of diffusion on the bulk flow flux with its partial quantity form was pointed too.

用矢量方法讨论了色谱模型中的轴向扩散项，指出轴向扩散项是扩散通量以分量的形式在主体流动通量上的页献。
