塑料薄膜透性测定技术研究

Study on the Testing of Permeability of Plastic Film

本文通过对塑料薄膜透过系数计算的数学模型的建立，得出了一种快速、准确和便利的测定塑料膜透性的新方法。测定试验结果表明，该方法是可行和实用的。因而，对修订透性测定的国家标准具有指导意义。

In this paper,the mathematical models for computing permeability ofplastic film(PPF)were established and a new method was developed,to test PPFrapidly,correctly and conveniently. It was resulted that the method was practicable and significantin modifying the Chinese standard of PPF testing.
