| 摘 要： | Under high relative humidity(RH) conditions, the release of volatile components(such as acetate) has a significant impact on the aerosol hygroscopicity. In this work, one surface plasmon resonance microscopy(SPRM) measurement system was introduced to determine the hygroscopic growth factors(GFs) of three acetate aerosols separately or mixed with glucose at different RHs. For Ca(CH3COO)2 or Mg(CH3COO)2 aerosols, the hygroscopic growth trend of each time...
