摘要
用磁流体力学方法分析了介质阻挡放电的击穿过程.在仔细分析介质阻挡放电中微放电的性质和介质对放电的影响的基础上,建立了一个理论模型来模拟各种参量对放电的影响,并导出了一组方程以描述微放电中等离子体的电子浓度、电场强度、电流密度等微观参量的演化过程.导出了电子浓度、电场强度、电流密度与工作气体的性质及器件结构的关系,并与已有的实验结果进行了比较.
With magnetohydrodynamic method.the breakdown process in a ndcrodischarge ofthe dielectric barrier discharge are analyzed. A theoretical model is established to simulate amicrodischarge on the basis of the properties of the microdischarge and the effect of the dielectric. Several equations are developed to depict the formation and evolution of the microscopic parameters in a single microdischarge. Some results about the relationships amongelectron density,electric current density,the property of the working gas and the device configuration have been reached and compared to experimental data.
