Abstract:
Deliquescence and efflorescence are the two most important physicochemical processes of aerosol particles. In deliquescence and efflorescence cycles of aerosol particles, many fundamental problems need to be investigated in detail on the molecular level, including ion and molecule interactions in supersaturated aerosols, metastable solid phases that may be formed, and microscopic structures and deliquescence mechanisms of aerosol particles. This paper presents a summary of the progress made in recent investigations of deliquescence and e2orescence processes of aerosol particles by four common spectral techniques, which are known as Raman/electrodynamic balance, Fourier transform infrared/aerosol flow tube, Fourier transforminfrared/attenuated total reflection, and confocal Raman on a quartz substrate.
Key words:  Aerosol, Deliquescence, Efflorescence, Raman/electrodynamic balance, Fourier transform in-frared/aerosol flow tube, Fourier transform infrared/attenuated total reflection, Confocal Raman

摘要:
风化和潮解是气溶胶微粒的两个最重要的基本物理化学过程. 气溶胶微粒的风化潮解循环中,过饱和气溶胶液滴中离子、分子间的相互作用,亚稳态固相,气溶胶颗粒的微观物理结构及预潮解机理,是比较重要的问题. 对电动态平衡/拉曼(EDB/Raman)、傅立叶变换红外/气溶胶流管(FTIR/AFT)、傅立叶变换红外/衰减全反射(FTIR/ATR)以及基底上共焦拉曼测量等四种常见的分子光谱学分析手段分别进行了介绍,并对相关技术在气溶胶微粒风化潮解过程研究中所涉及的重要问题和取得的重要进展,做出简单的总结.
