主　　题：dielectric barrier discharge electric field distribution electron avalanche Townsend discharge 

摘      要：The dielectric barrier discharge(DBD)in air at atmospheric pressure is not suitable for industrial applications due to its randomly distributed discharge *** this paper,the influence of the electric field distribution on the uniformity of DBD is theoretically analyzed and experimentally *** is found that a certain degree of uneven electric field distributions can control the development of electron avalanches and regulate their transition to streamers in the *** discharge phenomena and electrical characteristics prove that an enhanced Townsend discharge can be formed in atmospheric-pressure air with a curved-plate *** spectral analysis further confirms that the gas temperature of the plasma produced by the curved-plate electrode is close to room temperature,which is beneficial for industrial *** paper presents the relationship between the electron avalanche transition and the formation of a uniform DBD,which can provide some references for the development and applications of the DBD in the future.
