滤膜过滤器新的理论模型初步探讨

通过对滤膜过滤器的过滤机理进行分析，认为过滤器在使用期间，滤膜中每个毛细管的过滤性能随时间和空间位置的变化而变化，因而对过滤器性能的评价还应从系统的、全面的、宏观统计的观点来综合反映，由此可根据多孔介质流体动力学理论模型来准确地反映滤膜过滤器的性能变化。

Preliminary Study on New Theoretical Model of Membrane Filter

On the basis of analyzing the filtration mechanisms of membrane filter,the filtering features of each capillary in membrane are changeable with the time and spatial positions during operation.And filtering features of filter should be estimated comprehensively from the viewpoint of system and macro-statistics.Therefore,the character indicators of membrane filter can be studied more accurately by the fluid dynamics of porous media.
