摘要
用离散偶极子近似法，计算了立方粒子随机取向时在几种等效尺度参数下的光散射特性，并与等效球形粒子的光散射特性进行了比较．结果表明：立方粒子和其他非球形粒子与其等效球形粒子光散射特性之间的差别大致相同，说明对于随机取向的非球形粒子的光散射问题，粒子的内在对称性和表面的突变不会带来明显的效果．
Abstract Numerical calculations were carried out on light scattering by randomly oriented cubic particles for several size parameters.The scattering properties were analyzed and compared with those of the equivalent spherical particles.Results show that the differences between the scattering properties of cubic and spherical particles are similar to those between other non spherical and spherical particles.The results imply that the intrinsic symmetry and discontinuity of the normal direction of the particle surface have little effects on the scattering properties.
