摘　　要：鉴于以往微放电结构存在效率较低和放电均匀程度差的问题,提出一种基于介质阻挡放电(DBD)的新型微等离子体放电结构,该放电结构采用微腔网格形状电极。通过建立放电前后的等效模型,推导出放电功率公式,进行放电功率的影响因素分析实验,研究其电气特性及匹配电源问题。实验结果和理论分析基本吻合。随着电源电压和频率的增加,放电功率非线性增加。同时,放电效率较网-板、板-板结构DBD增加明显,传输电荷较网-板、板-板分别提高了11%和20%左右。Aiming at the problem of the lower discharge homogeneous and efficiency of conventional electrode structures,an approach is presented in terms of dielectric barrier discharge（ DBD） of a new micro-plasma discharge structure which employs a grid shape as the electrode. Before and after discharge,an equivalent model is established and the calculation formula of discharge power is deduced. Though a series of analysis experiments on influencing factors of discharge power,the reactor characteristics and the problem about matching power supply have been studied. Experimental results and theoretical analysis are consistent. Discharge power increases nonlinearly while the supply voltage and frequency increase. Meanwhile,discharge efficiency has increased significantly than that of ever net-board and board-board electrode structure DBD,transferred charges were increased by about 11% and 20% compared with net-board,board-board.
