Based on a mass balance equation, in this paper, the kinetic model of chromatography including influence of the radial diffusion on the mass transfer process is set up.
结果表明，溶质的径向扩散不仅对柱效、峰展宽、峰形特征等有影响，而且对溶质的保留时间也有一定的影响。
In addition, the effect of radial diffusion of fast electrons on the driven current during LHCD is considered by means of solving the current diffusion equation.
通过解电流扩散方程 ,考虑了快电子的径向扩散效应对驱动电流的影
