1. The diffusion flux of heavy metals has obvious fluctuation in different seasons, due to the changes in the redox potential.
   受到氧化还原条件的影响，重金属扩散通量在季节上变化较大。
2. 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。
