摘要/Abstract

摘要： 通过对保鲜膜多层叠加测定的气体透过率与薄膜叠加层数关系的研究，获得了气体透过率Q与试样叠加层数N的函数关系，从而可用多层叠加法测定的结果来导出单层薄膜的气体透过率，能获得较准确的测试结果，也拓展了压差法仪器的测量量程范围。

Abstract: The instrument′s detecting range was not accurate enough for detecting the gastransmission of single layer of plastic wrap when using differentialpressure method to detect the gastransmission. We detected the gastransmission of multilayer plastic wrap and found a relationship of the gastransmission and the layers of plastic wrap. Thus we could get accurate test results and expand the detection range of the instrument by use the relationship.

Key words: gas-transmission, differential-pressure method, plastic wrap
