为了能够对介质阻挡放电(Dielectric Barrier Discharge,DBD)的物理机制有更深入的理解,目前国内外许多学者采用电路模型仿真与实验相结合的方法来对介质阻挡放电进行研究,它们通过结合实际的试验条件,提出了许多不同的电路仿真模型。本文在华中科技大学张庭提出的电路模型基础之上,通过实验和理论计算分别得到了试验装置的介质电容和气隙电容,对该模型进行了仿真,并对仿真结果和试验结果进行了比较。在保持电感L和电源频率f及幅值不变的情况下,讨论了当记忆电阻Rmen和记忆电容Cmen变化时,放电电流从单峰模式向多峰模式的演变规律。并对电流脉冲的变化情况与记忆电阻和记忆电容的关系进行了探讨,以期能够对DBD的放电机理有更深入的理解。

In order to have a better understanding of the physical mechanism of DBD , many scholars at home and abroad has been using the way of circuit model simulation to conduct a study on Dielectric Barrier Discharge. They combine the actual test conditions and come up with a lot of different circuit simulation models. This paper is basedon the model propounded by Zhang Ting of HUST.I measured the capacitance of the dielectric and the gas gap,then simulated on the model with what had measured.Besides, comparison between the simulation results and the test results was made.I discussed bow the discharge currents evolutes from unimodal models to multimodal model with the memory resistor Rmem and the memory capacitor Cmem changed and the inductance L, the frequency f and amplitude of the power supply fixed and then discussed the relationship between changes of current pulse and the two parameters, Rmem and Cmem in order to have a better understanding of the DBD discharge mechanism.
