| 摘 要： | 介质阻挡放电(dielectric barrier discharge,DBD)是产生低温等离子体的重要方法,纳秒脉冲条件下DBD与普通交流下的放电不同。通过单极性纳秒脉冲激发大气压空气中DBD,计算纳秒脉冲DBD的电气参数,与交流或微秒脉冲放电的电气参数相比较,并对比放电图像与电流波形的关系,探讨了放电机制。研究结果表明,纳秒脉冲DBD的放电电流呈双极性,气隙上发生2次放电过程,其电气参数高于常规交流和微秒脉冲DBD的电气参数。随着空气间隙距离的增加,均匀放电向丝状放电的转化与电流脉冲波动相关。由于微放电持续时间与施加脉冲处于同一个数量级,且基本同时发生在气隙中,很难在同一位置上存在数个连续的微放电,这对放电的均匀性有利。

| Abstract: | Dielectric barrier discharge (DBD) is an important method of generating non-thermal plasma, and DBD generated by nanosecond-pulse is different from that by conventional AC power source. Characteristics of DBD driven by repetitive unipolar nanosecond-pulses in atmospheric air were investigated, the electric parameters were calculated, and the comparison of electric parameters for DBD under AC, microsecond-pulse and nanosecond-pulse excitation was conducted. The relationship between the discharge images and c... |
