| 摘 要： | 为了研究激光粒度测量颗粒分布时,测量区中处于运动状态的颗粒对衍射光空间分布和粒径测量结果的影响,从理论上分析了颗粒运动对衍射光的影响。结果表明:颗粒运动并不影响衍射光的空间分布,只改变衍射光的时域分布,因此对于颗粒粒径测量结果不产生影响。

| Abstract: | In order to research the influence of the particle's motion on the spatial distribution of diffraction light and particle size measurement when using the laser particle analyser to measure the distribution of particles,the influence of the particle's motion on diffraction light were analyzed in the-ory.The result showed that the particle's motion didn't affect the spatial distribution of diffraction light,only time domain distribution of diffraction light was changed,so the result of particles size measure was not affected. |
