中文摘要：

利用介质阻挡放电获得低温等离子体，开展了含氧气氛中利用低温等离子体转化NO的实验研究，研究了放电环境和添加C3H6对NO/O2/N2气氛中O3生成浓度与NO转化的影响。结果表明，冷却环境有利于O3的生成和NO转化率的提高；激励电压峰峰值升高时，O3生成浓度和NO转化率随之升高；添加C3H6有利于NO转化率的升高，且NOx浓度随激励电压峰峰值升高而下降；并探讨了NO／C3H6／O2／N2混合气放电时NO的转化机理。

英文摘要：

Abstract： The non-thermal plasma was obtained by dielectric barrier discharge under atmospheric pressure, and the experimental research about NO conversion in the oxidation atmosphere by non-thermal plasma has been conducted. The effect of discharge voltage on the 03 formation and NO~ conversion at different discharge space temperatures was investigated. The results show that elevated discharge space temperature is not conducive to O：~ fbrmation and NO conversion. When C：~H6 is injected into discharged gas, the gas oxidation was obviously enhanced. NO conversion increased and NOx concentration decreased with increasing discharge voltage. Finally the mechanism of NO conversion during the discharge in mixtures of NO/C3H6/O2/N2 was studied by gas component detection.
