摘要

利用针-板介质阻挡放电装置

在4 mm长的气隙中产生了大气压氩气射流等离子体。利用电学方法实现了对放电电流和电荷量的同时测量

并且对放电脉冲数和放电功率进行了研究;利用发射光谱法对放电等离子体进行了空间分辨测量

并根据ArⅠ 696.54 nm的Stark展宽计算了等离子体的电子密度。结果发现:随着外加电压的增加

每个周期内的放电脉冲数增加

放电功率也增加。随着针头距离的增加

电子密度由2.9410

-3

逐渐减小到2.2810

-3

。实验结果表明:电场强度对放电脉冲数和电子密度的空间分布起重要作用。

Abstract

An atmospheric argon plasma jet was obtained with a needle-plate dielectric barrier discharge system. The discharge gap was kept at 4 mm and the argon gas flow rate was 0.5 L/min. A test capacitor and a test resistance were connected in series in the circuit

and the discharge current and the transport charge were measured simultaneously. The average discharge power in a period of the applied voltage was calculated by Lissajous figure. The plasma jet was investigated spatially by optical emission spectroscopy

and the electron density was estimated by Stark broadening of Ar Ⅰ 696.54 nm. It is found that the discharge is asymmetric at different discharge phases

and more discharge current pulses are generated during the positive half cycle of the applied voltage. In addition

with the increasing of the applied voltage

the pulse number and the discharge power increase. Moreover

the plasma density is in an order of 10

-3

. With the increasing of the distance from the needle tip

the electron density of the plasma jet decreases from 2.9410

-3

to 2.2810

-3

. The results show that the electric field plays an important role in the discharge current number and the spatial distribution of the electron density.
