摘　　要：利用Mie散射与反常衍射理论的数值计算，对球形颗粒Mie散射和反常衍射作了大量详细的计算和分析比较，提出了相对折射率趋近于1的颗粒的反常衍射近似替代Mie散射的判据。In this paper, by numerical calculation based on Mie scattering and anomalous diffraction theories, we compared and analysed the Mie scattering and anomalous diffraction of spheres with refractue index near 1 in detail, and present a criterion of spheres with refractive index near 1 when anomalous diffraction theory can be used to replace Mie scattering theory.
