本文从理论上论征了用激光衍射法测定粉体粒度分布,用相干光获得了两种颗粒样品的衍射图样,利用特制的光电探测器测得了衍射图样的光能分布,并用计算机对所得数据进行了处理,获得了与样品参数相符的结果。
In this paper, the particle size distribution of powders was determined by laser diffraction method. The diffraction patterns of two kinds of particle samples were obtained by coherent light. The light energy distribution of the diffraction patterns was measured by a special photodetector. The obtained data Processed to obtain the results and the sample parameters consistent.
