The research on effects of Mie scattering light intensity by the size of micro-particles

根据Mie散射理论 ,研究了粒子线度对Mie散射光强的影响 ,不同性质的粒子 ,其影响效果不同 ,在固定入射波长条件下 ,散射光强随粒子线度呈周期变化 ,同时发现H2 O微粒子散射光强峰峰间距与粒子的线度和波长的关系可简单的表示为Δa =- 0 .1333+0 .2 2

Using Mie scattering theory, authes have researched the effects of Mie scattering light intensity by the size of micro-particles. Different of property of micro-particle cause different effects. When the incident wavelength are the constant, the scattering light intensity appearance periodicity oscillation. The peak-peak value period of scattering light intensity of H 2O can be described as Δ a=-0.133 3+0.222λ.
