摘　　要：在介质阻挡非平衡等离子体放电过程中,通过在电极两端施加电压,流经放电区域的气体被击穿,产生高能电子和激发态组分。这些活性粒子与气体分子发生非弹性碰撞引起分子的电离或离解,促进燃料的转化。本文主要从稀释气体、脉冲电压和燃料浓度三个方面进行研究,探讨不同稀释气体对放电过程中电流和反应区温度的影响、脉冲电压和燃料浓度变化时氨气的转化率及氢气生成的变化规律。In the process of dielectric barrier non-equilibrium plasma discharge,the gas flowing through the discharge region is broken down by applying voltage at both ends of the electrode,and high-energy electrons and excited components are produced.The inelastic collision between these active particles and gas molecules causes ionization or dissociation of molecules and promotes the conversion of fuel.This paper mainly studies the dilution gas,pulse voltage and fuel concentration,and discusses the influence of different dilution gases on the current and reaction zone temperature in the discharge process,the change law of ammonia conversion and hydrogen generation when the pulse voltage and fuel concentration change.
