摘      要：In this paper, various patterns of dielectric barrier glow discharge simulated by a phenomenological dynamic model are *** model is constructed based on the basic dynamic process of dielectric barrier glow discharge and involves the voltage-transfer characteristic as well as the lateral inhibition *** simulations, different driving voltage profiles are applied to achieve one or two pulsed discharges in each half-period and the corresponding pattern evolution is *** final stable patterns driven by a rectangular wave voltage organize simply as stationary striations or hexagonal *** patterns driven by a multi-step wave appear to be much more complicated, with complementary striations,concentric rings and square superlattices *** evolutions of these patterns from the initial uniform state are described and it is found that the spreading of the inhibition effect plays a key role in these *** numerical simulations in the present work are in excellent accordance with previous experiments and fluid *** dynamic model proves to be a convenient and promising approach to reproducing different pattern structures and pattern evolutions in dielectric barrier glow discharge systems.
