The structures of pamps molecule chains change along with the changes of solution environments ( ph and ionic strength ( i ) ) and thus affect the water flux and selective permeability of the composite membrane Pamps分子链的构象随溶液环境( ph值、离子强度等)的变化而变化，从而影响膜的渗透通量和选择透过能力。
Several factors which influence the production of douchi fibrinolytic enzyme were analyzed , including amount of soaking water , soaking time , crash degree of soybean , carbon source , ionic strength and cooking time 分析了影响豆豉纤溶酶产量的诸多因素，包括大豆浸泡水量、时间、大豆破碎程度、碳源、离子强度、蒸煮时间等。
The water flux decreases with increasing ph and increases with 1 . the bsa rejection is highest at the isoelectric point ( iep ) ( 4 . 8 ) , while decreases on both sides of iep . the bsa rejection increases as i decreases 在低离子强度(高ph值)溶液中，分子链伸展，膜通量较小；而在高离子强度(低ph值)溶液中，分子链收缩，膜通量较大。
The result showed that the diffusion coefficient of protein increased with increasing protein concentration , and that when the ionic strength increased gradually , the diffusion coefficient decreased with increasing protein concentration 结果表明在低离子强度环境中蛋白的扩散系数随蛋白的浓度增加而增加，随着离子强度的逐步增大，蛋白分子的扩散系数随其浓度的增加而减小。
