摘要

笔者研究了大气压下介质阻挡放电的产生及其发射光谱特性。放电施加正弦激励

频率和幅值分别是5

0 kHz和0

0 kV。通过高频数字示波器测量放电的电流电压。光谱特性通过发射光谱仪测量。光谱仪测量范围为200

100 nm

通过光谱分析以确定大气压下等离子射流的影响因素。结果表明:施加电压幅值是其首要影响因素

其次是频率;气体流速的影响因气体成分的不同而不同;纯Ar大气压等离子射流只能观察到活性例子Ar而没有Ar2

Ar+2或Ar+的光谱。

Abstract

This paper reports the results concerning the production of atmospheric-pressure plasma jets and its optical spectrum characterization. The discharge was produced by applying a sinusoidal voltage of frequency 5

0 kHz and potential difference of 0

0 kV across the electrodes. The discharge was characterized by measuring current and voltage with a high frequency digital oscilloscope. The optical spectrum characterization was made by taking the spectrums of discharge by optical emission spectrometer. The optical spectra in the range of 200 nm to1 100 nm have been analyzed in order to determine the influence factors of atmospheric-pressure plasma jets. The main influence factors of APPJs discharge is the amplitude of applie

d voltage

and the secondary factor is the frequency. The influence of gas flow rate on discharge is different by gas composition. moreover emission spectral of APPJs in pure argon can only observe spectral of Ar but Ar2

Ar+2 or Ar+.
