The moisture content of all materials tries to reach an equilibrium with the relative humidity in ambient air
物質(zhì)中的水份總是試圖與環(huán)境的相對濕度達(dá)到平衡
At equilibrium the relative humidity of the material is called equilibrium relative humidity ERH
物質(zhì)中的濕度達(dá)到平衡后稱為平衡相對濕度
Equilibrium relative humidity divided by 100
平衡相對濕度除以 100 A w = ERH / 100
