摘　　要：本文建立并完善了非对称膜及其复合膜结构参数对气体渗透影响的数学模型，以氢气、氮气为渗透气体，借助计算机，通过数学模型考察了膜结构的７个参数对气体渗透率和气体选择性的影响。Two mathematical model for connecting the structure parameters of asymmetric polymer membrane and its composite membrane on gas permeation have ben established and improved. The effects of seven membrane structure parameters on permeability and selectivity of H2and N2 have been studied with the help of computers using these mathematical models.
