中文摘要：

采用光谱法研究了大气压下氮气、氩气以及氩气对氮气介质阻挡放电等离子体的光辐射特性的影响。研究结果表明：在氮气里添加少量氩气,氮气光谱谱线强度会有所增强,尤其是386.3 nm和418.9 nm谱线强度增强明显。在氩气体积分数为10%时,随着等离子体放电电压变化,氮气的386.3 nm和418.9 nm两条谱线强度在放电电压70 kV时迅速增强。因此,在氮气和氩气混合气体放电中,气体组成影响等离子体内部的能量传输特性以及放电的发光特性。

英文摘要：

The characteristic of light emission with various process conditions in argon,nitrogen and argon/nitrogen admixtures Dielectric Barrier Discharge（DBD） at atmospheric pressure was investigated by Optical Emission Spectroscopy（OES）.It was found that the intensity of N2 spectral lines were increased,especially 386.3 nm and 418.9 nm,when added 10% Ar in the N2 plasma.The spectral lines of N2（386.3 nm and 418.9 nm） suddenly emerge with high intensity when the input voltage adds to 70 kV in the admixtures（ratio of Ar is 10%）.In other words,the component of mixture gas influences the optical characteristic and energy transfer peculiarity in gas discharge.
