Measurements of polarized light scattered from monodisperse nonspherical randomly oriented aerosol particles are presented along with Mie theoretical results for spheres of approximately the same cross sectional area. For slightly nonspherical particles of sodium chloride and potassium sulfate with size parameter (defined as the ratio of the particle circumference to the wavelength) greater than about five, the intensity of light scattered is generally more than as predicted by Mie theory in the forward scattering lobe, but less at nonforward angles. For particles with size parameter less than five, the Mie results more closely match the measurements. Measured angular scattering patterns for randomly oriented particles are smoother than the Mie theoretical results and are nearly the same for salt and potassium sulfate particles of the same size. Measurements of particle depolarization are nearly independent of scattering angle.
给出了从单分散非球形随机取向气溶胶颗粒散射的偏振光测量结果，以及横截面面积大致相同的球体的米氏理论结果。对于尺寸参数（定义为颗粒周长与波长之比）大于约5的氯化钠和硫酸钾的略非球形颗粒，在前向散射瓣中，散射光的强度通常比米氏理论预测的要大，但在非前向角度则较小。对于尺寸参数小于5的颗粒，米氏结果与测量值更接近。随机取向颗粒的测量角散射图案比米氏理论结果更平滑，并且对于相同尺寸的盐和硫酸钾颗粒几乎相同。颗粒去极化的测量几乎与散射角无关。
