摘　　要：提出一种新型的放电电极，采用表面滑闪预电离方式，解决脉冲氧碘化学激光器的稳定均匀放电问题．采用该放电电极，对碘甲烷和氮气混合气体进行放电．在放电截面为11cm×10cm，腔体压力为2．8-3.3kPa情况下，得到稳定均匀的辉光放电，电能量注入达4．5J/L．该放电电极构造新颖，在理论上，该放电电极可以在更大放电截面上取得良好的放电结果．A novel electrode system with the assistance of sur-face sliding pre-ionization was applied to improve the stability of the glow discharge with large aperture .The pre-ionization unit was symmetrically fixed on the plane of cathode surface . A uniform and stable glow discharge was obtained in the mix-ture of iodide and nitrogen with the specific energy deposition of 4.5 J/L, pressure of 2.8 -3.3 kPa, aperture size of 11 cm×10 cm.In theory , the electrode system is applicable in glow discharge with even larger aperture due to its unique pre-ionization structure .
