摘要
基于夫琅和费衍射 ,据数值积分计算了按粒径对数正态分布时颗粒群衍射光强的分布 ,作出在粒数及重量分布的参数不同时光强随衍射角的变化图 ,通过对比分析说明了分散度及中值直径对衍射图样中心强度、是否出现衍射条纹。
Based on Frunhofer-diffraction, the diffraction intensities of lognormal distribution particles is numerically culculated in th is paper. It is displayed in figures as a function of diffraction angle for the different number-size and wight-size distribution parameters. Influnce of the dispersity and medium particle diameter on the central intensity of diffraction pattern and production, the number, and the position angle of diffraction fr inge are introduced by comparing and analysing.
