This paper is aimed to investigate the effect of packing material on plasma characteristic from the viewpoint of charge transfer process. Both the charge accumulation and release processes in the dielectric barrier discharge reactor and packed-bed reactor were investigated by measuring voltage and current waveforms and taking ICCD images. The packing material was ZrO₂ pellets and the reactors were driven by a parameterized nanosecond pulse source. The quantity of transferred charges in the dielectric barrier discharge reactor was enhanced when decreasing pulse rise time or increasing pulse width (within 150 ns), but reduced when the gas gap was packed with pellets. The quantity of accumulated charges in the primary discharge was larger than the quantity of released charges in the secondary discharges in the dielectric barrier discharge reactor, but they were almost equal in the packed-bed reactor. It indicates that the discharge behavior has been changed from the view of charge transfer process once the gas gap was packed with pellets, and the ICCD images confirmed it.

本文旨在从电荷转移过程的角度研究封装材料对等离子体特性的影响。通过测量电压和电流波形并拍摄 ICCD 图像，研究了介质阻挡放电反应器和填充床反应器中的电荷积累和释放过程。填料为ZrO ₂颗粒和反应器由参数化的纳秒脉冲源驱动。当减少脉冲上升时间或增加脉冲宽度（在 150 ns 内）时，介质阻挡放电反应器中转移的电荷量增加，但当气隙充满颗粒时，电荷转移量减少。在介质阻挡放电反应器中，一次放电中累积的电荷量大于二次放电中释放的电荷量，但在填充床反应器中它们几乎相等。这表明一旦气隙被颗粒填充，从电荷转移过程的角度来看，放电行为发生了变化，ICCD图像证实了这一点。
