| 摘 要： | 根据经典的Mie氏散射理论，分析和计算了单个粉尘颗粒的散射特性曲线，又通过实验对粉尘云散射特性进行了研究，分析了散射角、粉尘粒径及水雾对光散射的影响.研究得出，单个粉尘粒子的散射光强随颗粒粒径的增大而增大，对粉尘云而言，粉尘中位径越大，灵敏度越小，测量的粉尘浓度值会偏低.

| Abstract: | According to the classic Mie ray scattering theory,analyzed and computed the scattering characteristic curves of a single dust,and also studied the scattering characteristic of dust cloud by experimental.Studied the influence on ray scatting caused by scatting angle,particle size distribution and fog,such important results are obtained: as scattering luminous intensity of a single dust granule increases along with the pellet particle size increasing,but for dust cloud if diameter of dust goes bigger,sensitivity goes more sluggish,then the dust concentration value surveyed will be somewhat low. |
