其中D是有效扩散系数，t是时间。二维情况可以通过适用于纸和薄层色谱的概念的扩展来描述，其中一维迁移伴随着二维分散（14）。因此，在两个位移步骤中的第一个步骤中，取时间t1，沿两个轴的沿着加宽可以描述为：
< r2= 2 Dt(1) where D is the effective diffusion coef-ficient and t is the time. The 2D case can be described by an extension of concepts applicable to paper and thin-layer chromatography where migration in one dimension is accompanied by dispersion in two dimensions (14). Thus in the first of two displacement steps, taking time t\, the broadening along the two axes can be described by
