Firstly, the development of the concentration polarization model or the force balance model is reviewed based on the back-diffusion and lateral migration of particles changing with process parameters.
首先是基于溶质微粒反向扩散或溶质微粒的横向迁移现象分别阐述了浓差极化类模型和力平衡类模型的发展演变过程；

浓差极化
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。
