摘　　要：采用荧光发射光谱和荧光时间分辨光谱,对H_(2)S分子进行了脉冲流光放电激发解离相关实验研究.将所得400~800 nm荧光谱线归属为S_(2)、S^(-2)、H、SH等活性粒子的发光.结果表明,H_(2)S气体脉冲流光放电等离子体中的主要活性粒子是H_(2)S*、S_(2)、S^(-2)、H、SH,且时间分辨光谱测量结果表明H和SH基荧光信号几乎同时出现,由此确定H_(2)S气体脉冲流光等离子体放电主要激发解离通道为H_(2)S+e*→H_(2)S*+e→H*+SH*.The excited dissociation process of H_(2)S by pulsed plasma streamer discharge has been studied by using plasma fluorescence spectra and time-resolved spectra.The fluorescence spectra between 400 and 800 nm have been assigned to the transition of S_(2),S_(2)^(-),H,SH.Experiment results indicated that the main flexibility particles are H_(2)S*,S_(2),S_(2)^(-),H and SH in pulsed plasma streamer discharge of H_(2)S.The results of time-resolved spectra indicated that the fluorescence signal of H and SH appeared almost simultaneously.The main excited dissociation channel of H_(2)S is H_(2)S+e*→H_(2)S*+e→H*+SH*.
