含空气杂质大气压氦气介质阻挡放电中彭宁电离作用OA北大核心CSCDCSTPCD
Investigation of Penning Ionization in Atmospheric Helium Dielectric Barrier Discharges With Air Impurity
进行大气压氦气介质阻挡放电,通过测量放电起始电压和发射光谱,研究本底空气压强BAP在0.8～1000Pa时放电中彭宁电离作用的变化规律.结果发现:BAP＜190Pa时,放电起始电压显著降低,N_2~+第一负区391.4nm谱线强度随BAP增大而增大;BAP＞190Pa时,放电起始电压显著线性增大,391.4nm谱线强度随BAP增大而逐渐下降,最终几乎趋于零.He原子的各谱线强度随BAP增大而逐渐递减.探讨其物理过程为:放电起始电压的结果和发射光谱…查看全部>>
The change law of Penning ionization in atmospheric helium dielectric barrier discharges (DBDs) with air impurity was investigated. Discharge inception voltage and emission spectra were measured under different background air pressures (BAPs) changing from 0.8Pa to 1000Pa. Results of these two kinds of methods showed that in a range of BAP from 0.8Pa to 190Pa, discharge inception voltage decreased obviously and the 391.4nm line intensity increased with the B…查看全部>>
