用于激光颗粒测试技术的非球形颗粒的椭圆衍射模型

A Non spherical Particle Ellipse Diffraction Model Used in Laser Diffraction Particle Sizing

激光颗粒大小测试的结果与颗粒形状密切相关。通过对椭圆衍射谱的研究，提出在激光粒度分析中以椭圆谱代替球形颗粒谱。计算机模拟计算与对金刚砂实测的结果表明椭圆衍射模型可以有效地抑制粒度反演结果的展宽。

There is a relationship between particle size measurement and particle shape. After studying the diffraction spectrum of non spherical particles, an ellipse particle diffraction model has been put fowerd. By using this model in laser particle size measurement data inversion,the particle size distribution spread can be restrained effectively.
