| 中文摘要 |
| 为了了解气溶胶折射率对研究大气气溶胶的辐射效应的影响,给出了一种基于气溶胶散射和吸收特性的有效媒介近似方法,以计算大气气溶胶的有效折射率。用此方法计算所得北京冬季气溶胶的有效折射率为1.561-0.057i,其与实测值(1.550-0.057i)相比是比较一致的。在此基础上,进一步探讨了大气气溶胶物质中烟尘含量和大气相对湿度对气溶胶有效折射率的影响。 |
| 英文摘要 |
| Based on the scattering and absorbing characteristic of aerosol,a effective medium approximative method was given, and the effective refractive index of aerosol was calculated.The calculated effective refractive index of the winter aerosol of Beijing is 1.561-0.057i,which is agreed with the observational value(1.550-0.057i).Using this method,.the effects of soot content contained in atmospheric areosol and the relative humidity on the effective refractive index were further discussed,and some useful conclusions were obtained. |
