FTIR-ATR (attenuated total reflection) technology was employed to observe the processes of deliquescence and efflorescence of sodium nitrate (NaNO3) aerosol particles at the molecule level.

• 应用FTIR-ATR(Attenuated Total Reflection)技术,在分子水平上对硝酸钠气溶胶微粒的潮解与风化过程进行观测。 作者首次报道在潮解过程中硝酸钠气溶胶微粒转晶,和两种不同风化行为的红外光谱特征。
