高次衍射对激光粒度分析的影响

The Ifluence of Higher Diffraction to Laser-Size-Analysing

本文介绍了激光测粒原理及高次衍射现象产生的原因,从理论上推导了高次衍射强度的分布公式,分析了高次衍射对激光测粒产生的影响,讨论了获得最大有效信号强度时颗粒在分散相中的最佳体积浓度。

This paper has intruduced the principle of Laser-Size and the reason how higher diffraction come into being, derived higher diffraction strength dispersing formula, analysed the influence of higher diffraction to Laser-Measuring-Size, and discussed the optimized volume consistency of grain in dispersion phase for obtaining the maximum signal strength.
