摘要
开发了一种由两个矩形铜电极组成的楔形放电装置,利用这种装置研究了楔形间隙内的氦气放电特性.发现了楔形氦气放电长度、放电电流和谱线强度随氦气流量的增加先快速增加,再缓慢减小,最后几乎不变的规律,但击穿电压却先缓慢减小,然后快速增加,最后几乎不变.得到了相应的特征分区图.建立了放电长度特征分区图、击穿电压特征分区图、放电电流特征分区图和光谱强度特征分区图之间的内在物理关联.
Abstract
A barrier discharge device composed of two rectangular copper electrode is developed to generate an atmospheric pressure helium discharge.This discharge characteristics generated in a wedge gap is studied.It is found that with the increase of gas flow rate,the discharge length along with breakdown voltage and spectral line intensity displays increase rapidly-decrease slowly-almost unchanged,but discharge current firstly decreases slowly,then increases rapidly,finally almost unchanged.The characteristic regions are obtained.The underlying physical correlation has been established among discharge length characteristic region,breakdown voltage characteristic region,discharge current characteristic region,and spectral intensity characteristic region.
