【摘要】 渗透性和粘流率是气体扩散分离膜的两个主要特性。根据其定义，推导出用于混合气体（H2-N2，H2－CO2和H2－CH4）分离的双层微孔金属膜的多数搭配关系式，并分析了骨架层渗透位变化对双层膜分离性能的影响。在此基础上，提出分离膜的理想结构。更多还原

【Abstract】 Permeability and rate of viscous flow are main characters of a separationrnernbrane in diffusion. By its definition a re1ationship equation for parametric ac-cordance of a two - layer microporous metal membrane for the use of gaseous mix-ture(H2-N2, H2-C02 和 H2-CH4 ) separation was derived. The influence of the per-meabillty change of the support layer on the separation properties of the two - layermernbrane was analysed and a ideal structure lf the separation rnernbrane was pre-sented.更多还原
