| 摘 要： | 用火花预电离辅助介质阻挡放电装置在大气压空气中实现了均匀的类辉光放电。通过用光谱模拟法和波尔兹曼图解法对N 2 第一负带系B2Σ→X 2Σ(0,0)带发射谱线的分析,对放电过程中N 2 的转动温度进行了诊断。研究了不同频率和放电模式下转动温度的变化规律,对由两种方法计算所得的温度进行了对比。实验结果表明,转动温度会随着外加频率的增加而缓慢的增加;当放电从类辉光模式变到丝状放电模式时,转动温度会有70K左右的升高。

| Abstract: | Uniform glow-like discharge is generated in a spark pre-ionization assisted dielectric barrier discharge device at atmospheric air. The emission spectrum of the 1st negative band of N2+( B2∑→X2Σ) (0, 0) has been analyzed by means of spectrum simulation and Boltzmann plot method, and the rotational temperatures have been diagnosed. The results show that the rotational temperatures vary with the applied frequencies and discharge modes, and about 70K higher than those in filament mode. |
