摘　　要：阐述了利用光学波动法测量颗粒浓度的原理。在实验条件下,测量了水平浓淡撞击式燃烧器出口不同距离截面的气固两相射流颗粒浓度分布,得到了各截面固相浓度分布、扩散和衰减规律,其结果可为分析电站锅炉燃烧稳定性、节能及燃烧器改造提供参考。图10。The principle of detecting particle density distributions by way of optical wave measurements is being elucidated. Under experimental conditions, the density distribution of gas-solid two-phase particles at the outlet of a horizontal rich-lean burner with a collision block was herewith measured in different cross sections and laws that govern particle density distribution, diffusion and attenuation were consequently obtained. These may serve as references for later analysis of combustion stability, energy saving and also for burner retrofit jobs of power plant boilers. Figs 10 and refs 9.
