kaasuläpäisyn
Kaasuläpäisy, known in English as gas permeability, refers to the property of a material to allow gases to pass through it. This process is driven by a pressure gradient across the material. The rate at which a gas permeates a material depends on several factors, including the nature of the gas, the properties of the material, and the temperature and pressure conditions.
Different materials exhibit varying degrees of kaasuläpäisy. For example, dense metals generally have very low kaasuläpäisy,
The measurement of kaasuläpäisy is often expressed as a flux, which is the amount of gas that
