| 摘 要： | 论述了组分在膜分离过程中的传递行为。简要论述了介质通过膜的途径，对膜传递过程中所产生的理论体系进行归纳和解释，并对其内在联系进行总结；最后根据介质与膜的相互关系，把组分在均质膜中的传递过程分为理想扩散过程、弱相互作用扩散过程、强相互作用扩散过程，并分别进行探讨。

| Abstract: | This article reviews the transport phenomena in various membrane separation systems.Some theory systems with different application background such as irreversible thermodynamic theory,statistical thermodynamic theory,fractional theory,solution diffusion theory and pore flow theory are summarized systematically,and their relations are analyzed.For the transport characteristics of dense membrane,the ideal diffusion process,weak interaction process and strong coupling process are catalogued and discussed. |
