摘　　要：使用一维流体模型,对比研究了半周期和全周期2种调制方式对大气压介质阻挡放电混沌控制的影响.结果表明,随着占空比的减小,放电从混沌经历多倍周期放电转变为单周期放电。相比于全周期调制,半周期调制下的混沌放电率先转变为单周期放电,且最终可以转变为对称放电。空间电荷的记忆效应是造成这种转变的主要原因.The effects of two modulation methods,namely half-period modulation and full-period modu­lation,on the controlling chaos in atmospheric pressure dielectric barrier discharges have been investigated by using a one-dimensional fluid model.It is shown that the chaotic discharges can transit into single-period discharges through multi-period discharges with the decrease of the duty cycle.The transition from chaotic discharges into single-period discharges under half-period modulation takes place earlier than that under full-period modulation.The transition is mainly due to the memory effect of space charge.
