在本文中，我们研究了纳秒脉冲介质阻挡放电（DBD）在一个中等的6 mm的放电间隙在不同的压力和脉冲重复频率（PRF）的增强电荷耦合器件（ICCD）图像的时间分辨的演变，使用干燥的空气及其成分的氧气和氮气。发现在空气、氧气和氮气中，当模式在均匀模式和非均匀模式之间转换时，压力有很大的不同。脉冲重复频率对模式转换也有明显的影响。脉冲介质阻挡放电的相变机制不是传统交流介质阻挡放电中的Townsend-to-Streamer。均匀模式下的脉冲介质阻挡放电由于一次雪崩的重叠而以平面电离波的形式发展，而压力的增加干扰了重叠，放电以流光的形式发展，对应于连续模式。通过预电离增加初始电子密度可以有助于在较高压力下的放电均匀性。我们还发现，均匀性对脉冲重复频率的依赖是一个非单调的。
In this paper, we investigate the temporally resolved evolution of the nanosecond pulsed dielectric barrier discharge (DBD) in a moderate 6 mm discharge gap under various pressures and pulse repetition frequencies (PRFs) by intensified charge-coupled device (ICCD) images, using dry air and its components oxygen and nitrogen. It is found that the pressures are very different when the mode transits between uniform and filamentary in air, oxygen, and nitrogen. The PRFs can also obviously affect the mode-transition. The transition mechanism in the pulsed DBD is not Townsend-to-Streamer, which is dominant in the traditional alternating-voltage DBD. The pulsed DBD in a uniform mode develops in the form of plane ionization wave due to overlap of primary avalanches, while the increase in pressure disturbs the overlap and discharge develops in streamer, corresponding to the filamentary mode. Increasing the initial electron density by pre-ionization may contribute to discharge uniformity at higher pressures. We also found that the dependence of homogeneity upon PRF is a non-monotonic one.
