摘　　要：本论文针对流场颗粒成像测量,通过对二维颗粒场成像图像的像点灰度分布、像点直径以及光照强度的影响等进行了研究,提出了流场像点图像的颗粒成像特性分析方法。基于像点直径的概念,推导了颗粒成像法测量颗粒场时的最大极限浓度估算公式。Imaging characteristics of particles were analyzed in two-dimension simulative flow fluid by quantitative image analysis, and obtained characteristics of image point in gray distribution, diameter, influence of illuminance. Analytical method was set up to multi image point of imaging particles. Base on the concept of image point diameter, formula was obtained to estimate concentration limit when particleimaging technique was used for measuring particulate flow.
