Pulsed discharge plasma and its application is one of the promising directions in civilian areas of pulsed power technology. In order to promote the research and development of the theory and application technology for pulsed discharge plasma, we have reviewed recent progress in the mechanism of nanosecond-pulse gas discharge and the characteristics and applications of typical pulsed plasma. Firstly, progress in mechanism of nanosecond-pulse discharge based on runaway electrons and measurement technology of runaway electrons is introduced. Then, research on characteristics of three typical discharges, including direct-driven pulsed discharge, pulsed dielectric barrier discharge, and pulsed plasma jet, is reviewed. Furthermore, typical plasma applications of surface modification, active flow control, ignition and combustion, and methane conversion are presented. Finally, the development trend on nanosecond-pulse gas discharge and pulsed plasma application are proposed based on the analysis of research status of pulsed discharge plasma.
