摘　　要：本文应用自制CS—135型渗透仪和渗透池,对聚酯薄膜等的气体渗透性进行测定,考察测定操作条件对测定结果的影响、同时对高聚物薄膜的气体渗透性问题和表征作了讨论。In this thesis,the permeability of polymer films(BOPET etc. )has been determined by CS-135 form permeameter,and the effect of detection conditions on the permeability determination has been studied. It has shown that pressure difference and temperature affect permeability determination. The characterization of permeability of gases across polymer films has been discoursed.
