We have conducted the experiment for clarifying relation between the accumulated charge on the dielectric in barrier discharges and discharge mode. In the experiments using an applied voltage with ringing parts, it was shown clearly that a uniform electric discharge mode is brought about by cancelling (or initializing) surface charge accumulated in the 1st pulse discharge by the 2nd relatively small pulse. Furthermore, we have constructed accumulated charge characterization equipment using the Pockels effect. This succeeded in observing the dynamic behavior of two-dimensional spatial distribution of the accumulated charge in plasma display (PDP) type surface discharge for the first time. In the Xe/Ne gas discharge for PDP, two-dimensional distribution became relatively uniform and was not able to employ efficiently the special feature of two-dimensional measurement of this equipment. However, when helium gas was used, electric charge accumulation began locally on the electrodes, and we were able to observe that charge accumulating domain spreads gradually. This technique was applied to the self-organized filamentary discharge mode which was the original purpose of this research. The amount of accumulated charges was zero in the part where a filament did not exist. In the part where a filament existed, the charge density of 67 nC/cm^2 was found to be accumulated per a filament. Finally, I would like to mention that it becomes possible to measure spatial distribution of the accumulated charge near the filament by using a thinner electro optic crystal as a future prospective. Moreover, by using together the image intensified CCD camera, it is possible to clarify the dynamic behavior of two-dimensional spatial distribution of the charge accumulation for one filament.

我们已经进行了实验，以阐明屏障放电和放电模式的介电电荷之间的累积电荷之间的关系。在实验中，使用带环零件的施加电压进行的实验，清楚地表明，通过取消（或初始化）表面电荷在第1脉冲放电中通过第二个相对较小的脉冲累积的表面电荷来实现均匀的电气放电模式。此外，我们已经使用Pockels效应构建了积累的电荷表征设备。这成功地观察了血浆显示中累积电荷（PDP）类型表面放电的二维空间分布的动态行为。在PDP的XE/NE气体排放中，二维分布变得相对均匀，无法有效地采用该设备的二维测量的特殊特征。但是，当使用氦气时，电荷积聚在电极上局部开始，我们能够观察到电荷累积域逐渐扩展。该技术应用于自组织的丝状排放模式，这是本研究的最初目的。在不存在细丝的部分中，累积费用的量为零。在存在细丝的部分中，发现67 nc/cm^2的电荷密度是根据细丝积累的。最后，我想提一下，可以通过使用较薄的电子光学晶体作为未来的前瞻性来测量细丝附近累积电荷的空间分布。此外，通过一起使用图像加强CCD摄像头，可以阐明一个细丝的电荷积累的二维空间分布的动态行为。
