1、Oxygen Permeability Coefficient : the product of the permeance and the thickness of film.
譯文：氧氣透過系數(shù)(PO2)：氧氣透過量與薄膜厚度的乘積。

2、At the same time, the solution to uniform air-gap permeance was analyzed.
同時也對均勻氣隙磁導的求解進行了分析。

3、Calculate the water vapor transmission, and permeance as follow.
按照下式計算水蒸氣透過率和水蒸氣透過系數(shù)。

4、XRD, SEM and single gas permeance were characterized to the ZSM-5 zeolite membranes.
用XRD,SEM和單組分氣體的滲透對膜進行了表征。
