广义米理论及其在粒度分析中的应用

Generalized Mie Theory and its Application in Particle Sizing

有形波束的散射问题在粒度分析测量仪器的研究中有着特殊重要的意义，本文介绍了处理均匀球形粒子对有形波束散射的广义米理论，并应用该理论研究了双柱形激光波束粒子测量系统的散射问题，与未理论和几何光学相比，其结果与实验吻合很好。

The scattering of a shaped wave beam has its special importance in instrumentation fur particle sizing.In this article,the generalized Mie theory (GMT) concerning tile scattering in homogeneously distributed sphericalparticles by shaped wave beams is introduced. The theory has been used ill the study of scattering from a particlemeasuring system by double cylindrical laser beams. As compared with tile results from A-lie theory or from geometrical optics, it has better agreement with the experimental results.
