1.Gas permeation is a process by which gas molecules can pass through a material, such as a membrane or a wall.
气体渗透是一种过程，其中气体分子可以通过材料
-
2. In gas permeation, the gas molecules are moving freely in the material, while in diffusion, they are forced to move.
在气体渗透中，气体分子可以在材料中自由移动，而在扩散中，它们被迫移动。
-
3. The gas permeation rate depends on the size and shape of the pores in the material, as well as theconcentration of the gas molecules.
气体渗透速率取决于材料中孔的大小和形状以及气体分子的浓度。
