The scattering of linearly polarized light by aerosol particles produces partly polarized light whose ellipticity is theoretically and experimentally investigated for the specific case of a continental atmospheric aerosol in a volume of air. With the Mie theory and under the assumption of various aerosol size-distribution models, the ellipticity has been computed as a function of the scattering angle for various wavelengths. The computations have been based upon complex indices of refraction: M = 1.5-0.0i, M = 1.5-0.0li, M = 1.5-0.li, M = 1.44-0.0i, M = 1.4-0.0i, M = 1.33-0.0i. The comparison between computed and measured values for the wavelengths of lambda = 0.45 micro to lambda = 0.65 micro discloses for dry aerosol a real part of the refractive index m = 1.50 and an imaginary part 0.01 <or=5 k > 0.1. With moist aerosol, the real part of the refractive index as well as the imaginary part decreases.
气溶胶粒子对线性偏振光的散射会产生部分偏振光，针对空气中大陆性大气气溶胶这一特定情况，对其椭圆率进行了理论和实验研究。利用米氏理论，并在各种气溶胶粒径分布模型的假设下，已计算出椭圆率随不同波长散射角的变化函数。计算基于复折射率：M = 1.5 - 0.0i、M = 1.5 - 0.01i、M = 1.5 - 0.1i、M = 1.44 - 0.0i、M = 1.4 - 0.0i、M = 1.33 - 0.0i。对于波长从λ = 0.45微米到λ = 0.65微米，计算值与测量值之间的比较表明，对于干气溶胶，折射率的实部m = 1.50，虚部0.01≤k＞0.1。对于湿气溶胶，折射率的实部和虚部均减小。
