As a condensable gas, the water vapor permeates through membranes become more complicated than non-condensable gases.

水蒸气作为一种可凝聚性气体，导致它在高分子膜中的渗透行为比其它非凝聚性气体复杂。

The vapor liquid two boundary layer model is applied to predict local mass concentration of the non condensable gas, temperature profiles and velocity profiles in the boundary layer.

该模型考虑了气、液膜之间的质量连续及能量连续特征。 对于不同的壁面过冷度，用数值方法首次求解并分析了边界层内局部不凝气体质量分数、温度和速度的分布规律。
