摘　　要：根据M ie散射理论,计算大气气溶胶主要微粒子的光散射光学截面和散射强度分布.结果表明,对流层和平流层中的微粒子在不同波段和粒径下,对光的散射能力不同.并模拟了散射场传播形成的彩色环,衍射彩色环包含了粒子的尺寸和光学特性信息.Based on the Mie scattering theory, the optics cross section and scattering intensity distribution of aerosol primary particles which IAMAP proposed were computed. Results show that under the different incidence wavelengths and particle radii, the scattering capability of particles are different. The glory of scattering fields was simulated. The diffraction glory by the scattering fields comprise the information of particle size and optics characteristics.
