英文摘要	a one-dimensional self-consistent fluid model was employed to investigate the effect of the driving frequency on the discharge modes in atmospheric-pressure argon discharge with multiple current pulses. the discharge mode was discussed in detail not only at current peaks but also between two adjacent peaks. the simulation results show that different transitions between the townsend and glow modes during the discharge take place with the driving frequency increased. a complicated transition from the townsend mode, through glow, townsend, and glow, and finally back to the townsend one is found in the discharge with the driving frequency of 8 khz. there is a tendency of transition from the townsend to glow mode for the discharge both at the current peaks and troughs with the increasing frequency. the discharge in the half period can all along operate in the glow mode with the driving frequency high enough. this is resulted from the preservation of more electrons in the gas gap and acquisition of more electron energy from the swiftly varying electric field with the increase in driving frequency. comparison of the spatial and temporal evolutions of the electron density at different driving frequencies indicates that the increment of the driving frequency allows the plasma chemistry to be enhanced. this electrical characteristic is important for the applications, such as surface treatment and biomedical sterilization.
