【摘要】 分别用直径0.22μm和0.494μm的粒子与过滤的蒸馏水制成不同浓度的悬浮液作为散射粒子场,来寻求用散射光分析未知群粒子场粒子性质的新的方法。实验结果表明,群体散射场侧向散射光的退偏振情况与粒子的直径密切相关,直径大的粒子其水平方向线偏振度远小于直径小的粒子,而其垂直方向的线偏振度却远大于直径小的粒子,此结论可用作探测未知群粒子场粒子性质的新方法。更多还原

【Abstract】 The suspending liquid consists of various concentrations of particles which are either 0.22μm or0.494μm in diameter and which were mixed into filtered,distilled water,and serve as the scattering medium forstudying the new method to analyze the particle’ s property in the unknown multiple particle field by using thescattered radiation.The experiment results show that the de-polarization of side-scattered radiation is very sensi-tive to the variation of the diameters of the particles:the horizontal polarization degree of the radiation scatteredby the particles with smaller diameters is much higher than that with larger diameters,but the vertical polariza-tion degree of these particles is much lower than those with larger diameters,this conclusion can be used as a newmethod to detect the property of the particles in the unknown multiple particle field.更多还原
