摘　　要：综述了由热致相分离法制备多孔膜的成膜机理．分析了由Gauss曲率的特性决定的分为椭圆形、抛物线形和双曲形的孔结构．建立了孔结构和相分离动力学过程:成核、聚结、旋节线分相之间的关系．Formation mechanisms of the porous membranes, which were prepared by thermal induced phase separation, were reviewed. Pore structures were classified as three types： elliptic, parabolic and hyperbolic, by the characterization of their Gaussian curvatures. Relationship between the pore structure and the kinetics process of phase separation （nucleation, growth and coalesce） was also established.
