摘    要:采用特殊设计的气体介质阻挡放电实验装置,对大气压氩气放电六边形斑图的放电信号及激发光谱进行了测量.采用发射光谱强度比法,计算了放电丝呈六边形斑图时的电子激发温度.实验发现,随着驱动电压频率的升高,六边形斑图的电子激发温度明显升高,各放电通道之间的放电时间相关程度提高.该工作对控制斑图的形成和研究斑图动力学具有重要参考价值.

关 键 词:斑图  介质阻挡放电  电子激发温度  时间相关性

Abstract:The emission spectrum and the discharge current waveform of argon dielectric barrier discharge at atmospheric pressure were measured when the filaments self-organized in hexagon pattern by using a specially designed experimental setup. Electron excitation temperature of hexagon pattern was calculated using intensity ratio method. It was found that the electron excita tion temperature is higher as the frequency of feeding voltage increases. And the temporal correlation among all micro-discharge channels also becomes higher as the frequency of feeding voltage increases. This work gives useful reference for studying pattern formation dynamics.
Keywords:Patterns  Dielectric barrier discharge  Electron excitation temperature  Temporal correlation
