| 摘 要： | 应用Mie散射理论对紫外光下TiO2微粒光散射特性进行了理论分析与数值计算,得到了散射强度分布、偏振度与散射角、散射强度与参数X以及光学截面与粒子半径的关系。结果表明,前向散射强度随着粒子半径的增大而增强;当粒子半径为50 nm左右,散射截面和吸收截面达到最大值。

| Abstract: | The theoretical analysis and numerical calculations of TiO2 particle's light scattering characteristics were carried out using Mie scattering theory. Moreover, the distributions of scattering intensity and scattering angle, polarization rate and scattering angle, scattering intensity and size parameter X, optic section and particles radius were presented. The result showed that the larger radius of particle is, the larger forward scattering intensity is;the absoption cross-section and scattering cross-section possess of a peak value when particle's radius is approximately 50 nm for TiO2 nanoparticle. |
