不同混合方案对气溶胶辐射特性的影响

利用体积权重平均，Maxwell-Garnett和Bruggeman理论，分别处理半径为0.5 μm 75%H₂SO₄气溶胶和黑碳气溶胶(BC)，以及硫酸盐气溶胶与黑碳气溶胶内混合的情况，求出其复折射指数.利用Mie理论计算内混合单个气溶胶粒子在0.55 μm波长处的辐射特性参量，其目的在于比较分析3种不同混合方案处理的同一混合情况下内混合单个气溶胶粒子辐射特性的差别. 结果表明:辐射特性的总体变化趋势大致相同，但采用不同的混合方案处理相同的内混合情况时，其结果在黑碳混合比为10%～30%时差异较大. 

Effect of Different Mixing Scenarios on Aerosol Radiative Properties

This paper used volume weight average, Maxwell-Garnett and Bruggeman mixing scenarios to analyze internal mixing of black carbon and sulfate or vitriol (75%), computed the effective refractive indices, and then computed the radiative properties of three mixing scenarios at the wavelength of 0.55 μm through Mie Theory. This paper aimed at comparing the differences of radiative propertiesof the three different mixing scenarios when studying the same situation of internal mixing. This study showed that the overall trends were similar for all scenarios, but when using the different mixing scenarios to simulate the internal mixing of the same state, the results varied; the maximum difference occurred when the content of black carbon was 10%-30%.
