Penndorf和Shifrin-Punina在前向散射角的Mie解的近似扩展到更小的尺寸参数值。目前的近似，方程。(7)当折射率m = 1.33时，Mie公式的计算精度可达x ~ 0.5-1.0，当折射率m = 1.33时，Mie公式的计算精度可达x ~ 2.0。这一结果的影响进行了讨论，相对于重建的粒度分布利用Shifrin Fymat分析反演公式的前向散射强度。
The approximations of Penndorf and Shifrin-Punina to the Mie solution at forward scattering angles are extended to smaller size parameter values. The present approximation, Eq. (7), is found to represent accurately the Mie result down to x ~ 0.5-1.0 for refractive index m = 1.33, and to x ~ 2.0 for much larger index values. The implications of this result are discussed relative to the reconstruction of particle size distributions utilizing the Shifrin-Fymat analytical inversion formula of forward scattered intensities.
