氩气/空气介质阻挡辉光放电特性研究

采用水电极介质阻挡放电装置,在低气压氩气(氩气体积分数为99.9%)和空气混合气体中实现了辉光放电.辉光放电比较均匀、稳定,其典型特征是在每半个周期内有1个电流脉冲.采用光谱方法,研究了辉光区域内,电子激发温度和氮分子(C3Ⅱu)的振动温度的变化情况.发现在产生辉光区域内,电子激发温度和氮分子(C3Ⅱu)的振动温度几乎不变.

Study on Characteristics of Dielectric Barrier Glow Discharge in Argon/air

The glow discharge is obtained at low pressure in argon(99.9%) /air by using a dielectric barrier discharge with water electrodes.It is found that the glow discharge is uniform and stable.Its typical characteristic is the discharge current presents one peak per half-cycle.Electron excited temperature and vibration temperature are studied in regions of glow discharge by using emission spectra.It is found that the electron excited temperature and vibration temperature almost retain constant.
