摘　　要：建立介质阻挡放电实验系统,研究大气压下外加放电峰值电压和气体组分对气体放电效果的影响。实验研究表明,提高外加放电峰值电压,电子密度明显增加;添加氩气后,观察到明显的潘宁效应,并得出了大气压下获得气体均匀放电的途径。The experimental system of dielectric barrier discharge was established,and the effects of the additional discharge peak voltoge and gas composition on gas discharge was investigated under atomspheric pressure.The results showed that the electron density rose obviously with the increase of additional discharge peak voltage.Penning effect was observed when adding argon to the gas mixture,and the approaches to uniform discharge at atmospheric pressure were obtained.
