多孔材料透过性能的表征

Expression of Permeation Property of Porous Materials

摘要:

透过性能对用于过滤分离、流体混合、布气分流等方面的多孔材料是一项十分关键的质量指标。主要介绍了多孔材料透过性能的表征方式，包括流体流动的基本概念、层流条件下流体的透过性能表征、多孔材料透过性能的综合表征、气体透过多孔材料时渗透系数的具体表征等方面。

Abstract:

The permeation character is a very important quality index as to porous materials which are utilized for filtration and separation, fluid blend, gas distribution and split-flow, and so on. The token ways are introduced for the permeation behavior of porous materials, with contents including the basic concept of fluid flow, the expression of permeation character of fluid under laminar flow, the synthetical token of permeation character of porous materials, the concrete expression of osmotic coefficient of gas through porous materials, and so forth.
