摘要
利用真空压力法和体积法对高分子薄膜的透气性能进行了比较．得出真空压力法适用于多种透气量的高分子薄膜的透气性能测定，体积法测试范围大，对大透气量的膜及复合膜、多孔膜测试结果比较准确．对膜材料的性能测试及选择具有一定的实用价值．
The permeability of polymer membrane is measured by vacuum pressure method and volume method, respectivelly and the results are compared. It is found that the former method is suitable for measuring the permeability of polymer membrane with multiple permeation capacity and the latter has a wide measuring range and more accurate measurement for compound, porous, and heavy permeable membranes. Both the methods are of practical for permeability measurement and selection of membrane materials.
