浓差极化是指分离过程中，料液中的溶液在压力驱动下透过膜，溶质(离子或不同分子量溶质)被截留，在膜与本体溶液界面或临近膜界面区域浓度越来越高;在浓度梯度作用下，溶质又会由膜面向本体溶液扩散，形成边界层，使流体阻力与局部渗透压增加，从而导致溶剂透过通量下降。
浓差极化(concentration polarization)：由电极反应过程中电极表面附近溶液的浓度和主体溶液的浓度发生了差别所引起的电极电位偏离平衡电位的现象

浓差极化阻力 concentration polarization resistance
We find:Surface deposited resistance,blockage resistance and degree of membrane fouling are positively correlated,while have a negative correlation between membrane itself resistance,concentration polarization resistance and degree of membrane fouling. Membrane flux is inversely related to degree of membrane fouling.
研究发现:表面沉积阻力、膜堵塞阻力与膜污染度呈正相关;膜自身阻力、浓差极化阻力与膜污染度成负相关;膜污染度与膜稳定通量呈高度负相关。
