According to the results, the activationenergy for migration of grain boundary Q was calculated. With the increase of the amount of re, the value of Q increases.
根据实验结果，对奥氏体晶界迁移激活能(Q)进行了计算，计算表明随稀土加入量增加，Q值亦增加。

The migration of oxygen ions in materials needs higher activationenergy. The decrease of membrane thickness is one of the effective ways for obtaining higher oxygen permeating flux.
