利用毛细管模型推导出双层陶瓷膜纯膜阻力并经实验得出其中的参数；通过以陶瓷膜为过滤介质的功态旋叶压滤机中的微滤实验，研究了阻塞系数Ｋ的影响因素 The capillary membrane model was used to derive the pure membrane resistance of the double-layered ceramic membrane and the parameters were obtained through experiments. The influencing factors of the blockage factor K were studied through the micro-filtration experiment in the rotary vortex filter with the ceramic membrane as the filter medium.
