摘要

在過去米氏理論(Mie Theory)是被做過許多研究的，但是它的物理現象卻是複雜而且不直觀的，在日常生活中，有很多米氏散射行為及應用，本論文主要是研究米氏散射的散射效率、吸收效率、消光效率、後散射效率、散射截面和散射係數的計算，在可見光波段下，討論不同的粒子大小和不同折射率材質的粒子散射係數的影響，以及粒子在不同折射率的兩個環境底下，在空氣的光散射，和在水中的光散射討論。

In the past, Mie theory has done many studies, but its physical phenomenon is complex and not intuitive. In everyday life, there are a lot of Mie scattering behavior and application. This thesis is to study Mie scattering of scattering coefficient in the visible light band, discuss the effect of different particle sizes and materials of different refractive indices of the particle scattering coefficient, and the particle in the environment under two different refractive indices, the light scattering in the air, and in water light scattering discussed.
