It has been shown that thin-film dialysis can be performed in such a way that the limiting rate is the rate of entry of the solute into the membrane from the high-concentration side. The rate of diffusion, therefore, reflects the probability of a molecule entering the pores on the surface and does not depend on the resistance to diffusion offered by the internal structure of the membrane. The good correlation, so generally found, of the order of escape times of given solutes with the order of free diffusion rates is thus explained. The data from stretching experiments with wet cellophane, in which the pore structure is distorted, are also explained.
已经表明，薄膜透析可以以这样一种方式进行，即极限速率是溶质从高浓度侧向膜内进入的速率。因此，扩散速率反映了分子进入表面孔隙的概率，而不取决于膜内部结构所提供的扩散阻力。由此解释了通常所发现的给定溶质逸出时间顺序与自由扩散速率顺序之间的良好相关性。对湿玻璃纸进行拉伸实验的数据也得到了解释，在该实验中孔隙结构发生了扭曲。
