| 摘 要： | 由直径0.22μm或0.494μm的粒子与过滤的蒸馏水混合构成不同浓度的悬浮液,作为研究粒子侧向散射光偏振特性的散射介质.实验结果表明,粒子侧向散射光的退偏振对粒子直径的变化非常敏感：直径小的粒子其侧向散射光水平方向偏振度远大于直径大的粒子,而其侧向散射光垂直方向的偏振度却远小于直径大的粒子.

| Abstract: | The suspending liquid consists of various concentrations of particles which are either0.22μm or0.494μm in diameter and were mixed into filtered,distilled water,and serve as the scattering medium forstudying the polarization property of radiation side-scattered by the particles.The experiment results showthat the de-polarization of radiation side-scattered by the particles is very sensitive to the variation of theparticles’diameters: the horizontal polarization degree of the side-scattered radiation of the particles withsmaller diameters is much higher than that with larger diameters,but the vertical polarization degree of theside-scattered radiation of smaller particles is much lower than that of larger particles. |
