摘要 基于异常衍射理论和修改 Rayleigh-Debye 近似,在衔接形式的一个身体上现实主义的模型被描述接近粒子的散布阶段功能。什么时候与准确方法相比,这里报导的衔接的技术提供合理近似给 Mie 在大量角度和尺寸参数上结果,并且它表明是的优点计算联盟者经济。另外,新阶段功能模型能实质上被扩大到另外的形状并且方便地在更复杂的散布和与放射的转移方程的答案有关的排放问题使用了。 Based on anomalous diffraction theory and the modified Rayleigh-Debye approximation, a physically realistic model in bridging form is described to approximate the scattering phase function of particles. When compared with the exact method, the bridging technique reported here provides a reasonable approximation to the Mie results over a broader range of angles and size parameters, and it demonstrates the advantage of being computationally economic. In addition, the new phase function model can be essentially extended to other shapes and conveniently used in more complicated scattering and emission problems related to the solutions of the radiative transfer equations.
