| 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。 |

| 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. |
