Permeance (P): The ratio of the gas transmission rate to the difference in partial pressure of the gas on the two sides of the film.
译文：气体透过系数（P）：单位时间内单位压力差下稳定透过单位面积上单位厚度的试样的气体体积。
After inflexion, the permeation flux is directly proportional to the difference of the square root of the vapour partial pressure on both sides of the membrane.
冷侧真空度拐点后膜的通量与膜两侧水蒸汽分压平方根的差成直线关系，这种关系说明了水蒸汽在膜孔内的传质过程是以扩散为主；
Oxygen Permeance (PO2) : the ratio of the O2GTR to the difference between the partial pressure of O2 on the two sides of the film.
译文：氧气透过量(PO2)：氧气透过率与薄膜两侧的氧气分压差的比值。
The results showed that the activation energy increased with the increase of oxygen partial pressure, while the enthalpy difference between the as-deposited and the crystalline states decreased.
计算结果表明，随着溅射时氧分压的增加，薄膜的结晶活化能增加，而相应的非晶态与晶态之间的焓差则呈现出相反的变化趋势。
