摘　　要：介质阻挡放电(DBD)能在大气压空气环境下形成稳定的放电,工业应用比较广泛。同轴结构电极的放电过程比较复杂,因此需要通过研究其放电过程中的各个参数来表征其放电特性,从而得到其放电机理。通过实验研究和结果分析,从电荷量的传输、放电功率以及气隙电压变化等几个方面分析了同轴结构电极的介质阻挡放电的放电特性,得到在大气压敞开环境下,同轴结构电极的介质阻挡放电的放电功率和放电电荷均有所不同,放电功率从数瓦到十几瓦,介质电容为数百皮法和气隙电容为数十皮法,均随电压的增大而增大;在放电过程中,管-管结构电极的介质电容和气隙电容的值均大于线-管结构。Dielectric barrier discharge （DBD） can form a stable discharge in atmospheric air environment, the industrial application is more extensive. The discharge process of the Coaxial structure electrode is more complicated, therefore, it is necessary to characterize the discharge characteristics by studying the various parameters of the discharge process, thus, we get its discharge mechanism. Through experimental research and result analysis, the discharge characteristics of the dielectric barrier discharge of the coaxial structure electrode were analyzed from the aspects of charge transfer, discharge power and air gap voltage variation, we that at the open atmospheric pressure, the discharge power and discharge charge of the dielectric barrier discharge of coaxial structure electrode are different, the discharge power from several watts to more than ten watts. The dielectric capacitance is hundreds pF and the air gap capacitance is tens pF, and both increase with increasing voltage; In the discharge process, during the discharge process, the values of the dielectric capacitance and the air gap capacitance of the tube-tube structure electrode are greater than that of the ray-tube structure.
