摘    要:在西安、南京采集111个气溶胶样品,测定了虚折射率ni和分析了粒子中Si、Al、Ca、Fe、K、Mg、Mn、Na、Ti、S、P、Pb和Zn的含量。统计分析表明,ni与S和Pb的相关系数r最高,分别为0.36和0.30,统计检验也表明,这一相关性是显著的。其它11种元素与ni的相关性较差,且并不显著。西安气溶胶S含量明显高于南京,它与ni之间的相关系数高出南京近一倍。这些结果表明,除碳C之外,气溶胶中的S和Pb及其化合物对辐射的吸收不能忽视。

关 键 词:气溶胶 虚折射率 元素 相关性 硫 碳 硅 铝 铅

Abstract:We have measured the imaginary refractive index n i of 111 atmospheric Al,Ca,Fe,K,Mg,Mn,Na,Ti,S,P,Pb and Zn.Statistic analysis shows that correlation coefficients between n i and S,Pb,which are 0.36 and 0.30 respectively,are larger than that of others,and statistic test shows the correlation was notable.Content of element S in Xian was obviously higher than that in Nanjing.The correlation coefficient between n i and S doubles compared with that in Nanjing.Our results show that absorption of radiation by S,Pb and their chemical compounds cannot be ignored,besides element C.
Keywords:Atmospheric Aerosol Imaginary Refractive Index Element Correlation
