Abstract: A theoretical computation equation of Ficks law in matrix form is given for predicting the cross - term coefficients in binary diffusion, and the results are extended to 3 - component and multicomponent diffusion systems. Finally, a generalized equation of Ficks law is obtained.

摘要: 对多孔固体表面扩散二元系统给出Fick定律交叉项扩散系数矩阵形式的计算式,并将其推广到三元及多元扩散系统,得到Fick定律交叉项扩散系数普遍化的计算式。
