在含MgO薄膜的两个平行石英板之间的rf （500 kHz）介质阻挡放电中，观察到对称自组织放电丝。细丝的排列被限制在石英石板材平面上的中心周围。随着电压的增加，灯丝的数量增加，灯丝排列的面积也增加。如果使用带有MgO膜的石英板，灯丝的排列不会移动，而没有MgO膜的整个排列会旋转。根据电流-电压测量结果，洛伦兹引力比库仑斥力小得多。这表明在二维库仑系统的抛物势中存在约束势。然而，一些细丝的排列与库仑系统中带电粒子的排列不匹配，这表明约束势不是纯抛物线型的。(C) 2003年美国物理研究所。
Symmetric self-organized discharge filaments have been observed in the rf (500 kHz) dielectric barrier discharge of Ar gas between two parallel quartz plates with a MgO film. The arrangement of the filaments is confined around the center on the quartz plate plane. With increasing voltage, the number of filaments increases, and the area of filament arrangement also increases. The arrangement of the filaments does not move if the quartz plate with a MgO film is employed, while the whole arrangement rotates without a MgO film. According to the results of current-voltage measurements, Lorentz attractive force is much smaller than Coulomb repulsive force. This suggests that a confinement potential exists as in the case of two-dimensional Coulomb systems in a parabolic potential. However, some of the filament arrangements do not match to those for charged particles in the Coulomb systems, which suggests that the confinement potential does not have pure parabolic profile.
