| 摘 要： | 本文提出了一个新的理论模型用以关联沸石单晶膜的渗透行为，根据这个模型，一定温度下，当渗透侧的压力接近于零时，气体的渗透速率与进料压力成正比，如果一组气体的分子明显小于沸石的孔径，而且与沸石骨架的物化作用彼此也相近，那么任意两者之间的渗透速炫之比等于它们分子量的平方根反比。

| Abstract: | The pemeation behavior of the zeolite single-crystal membrane has been correlated with a new theoretical model,according to the permeation rate is proportional to the feed pressure at a certain temperature when the outlet pressure is nearly zero.For the gases which are considerablely smaller than the diameter of zeolitic pores and have very similar physical and chemical interaction with the zeolite skeleton,the ratio of the permeation rates of every two gasses equals to the reciprocal of the square root ratio of their molecular weights. |
