摘要

为探究大气压氩气条件低载气流量下介质阻挡放电的放电特性

通过拍摄放电图像、光谱分析、测量放电波形图等手段研究了大气压氩气条件下介质阻挡放电（DBD）的放电特性。分别考察了电压、频率、气隙间距和载气流量等参数对DBD特性的影响。实验结果表明:提高外加电压幅值和频率可以显著增强放电功率。提高电压幅值会产生更多的高能电子

提高放电频率可以改变高能电子的分布

使得高能量电子数密度升高

低能量电子数密度下降。气隙间距的减小可以明显提高放电均匀性。载气流量增大时

放电强度下降

但放电均匀性会得到提高。

Abstract

In order to learn the discharge characteristics of dielectric barrier discharge with low flow rate under atmosphere pressure with argon

by means of taking discharge photographs

performing spectral analysis

measuring discharge waveform

and so on

the DBD characteristics with low flow rate in argon at atmospheric pressure was investigated. The effects of discharge voltage

frequency

gas discharge gap

and air flow rate were also investigated. The results show that the rise of applied voltage and frequency can improve the discharge homogeneity. And it can get more energetic electrons when the applied voltage increases. With the increase of frequency

the distribution of energetic electrons will change

the density of electrons with higher energy will increase

and the density of electrons with lower energy will decrease. With the decrease of air gap

the discharge uniformity will increase. With the increase of air flow rate

the intensity of discharge weakens

whereas the uniformity of discharge increases.
