        摘要：The fundmental function and mechanism of carrier membrane controlled by proton, heat, light and oxidation-reduction reaction are introduced in detail. Carrier membrane as a high function membrane can make full abvantage of interactions between substances to select objective one. It has been greatly concerned in the past twenty years. The most important character is its active transport to objective substance, i. e. the transport from lower to higher concentration. Thus we can design optional carrier for characteristic substances. Then we can separate or concentrate them or artificially control the transport with carrier switched by heat, light, electricity, etc.

        摘要：The Induction-Filming Polymerization is a novel method for making polymer/polymer composite membranes. Here a polymer solution which act as a induction-Filming agent will induce the monomers filming, and a polymer/polymer layered composite mambrane with a IPN interface is prepared after the monomers have been polymerized.
