分析了国内外基于压差法的塑料薄膜透气性测试装置的研究现状，总结了影响满足国家标准要求的透气性测试装置测试性能的主要因素。指出了单密封结构的测试装置难以满足高阻隔性薄膜透气性的测试要求，提出了合理处理高阻隔性薄膜透气性测试问题的途径。

Research status of plastic film permeability test device based on differential pressure method at domestic and abroad was reviewed. The main factors influencing test performance of text device meeting national standard were analyzed. It was concluded that single-sealed structure can not meet the requirements of high barrier film permeability test. The way to deal with the measurement of high barrier property test was proposed.
