摘　　要：电晕放电是治理环境污染物的一种有效手段,使用光电倍增管作为光谱探测设备,以紫外光谱成像技术作为两相体直流电晕放电的研究方法,分析了常见气固两相体的直流电晕放电特性,得到空气和气固两相体颗粒的直流电晕放电光斑亮度和起晕电压不同,这些结论是与颗粒的介电常数有关。Corona discharge is an effective measure to control the environmental pollutants. Photomultiplier was used to the device of the spectrum detection, and the UV spectral imaging technology was used to investigate method of DC corona discharges of two-phase mixture. The discharge properties of gas-solid two-phase mixtures were analyzed, and the facula brightness and critical coronal voltage of air and gas-solid two-phase mixtures particles were different. The conclusions are associated with the dielectric constant of the particles.
