中文摘要：
在近大气压介质阻挡放电中，研究了六边形斑图的空间波长随放电参数的变化，仔细观察了稳定的六边形中放电通道的产生及运动行为．结果表明空间波长随电压增加而减小，变化曲线与放电间隙和气压有关．电压升高，边界处生成新的放电丝，位于六边形最外层顶点处新生成的放电丝沿径向运动，而位于六边形边长上新生成的放电丝的运动方向平行于距其最近的C2轴（过六边形顶点）．继续升高电压，放电丝变为条状进而形成螺旋渡或靶波．在观察实验结果和分析放电丝受力的基础上，认为放电区域可能存在一种类似二维库仑晶体中存在的约束势．
英文摘要：
The spatial wavelength of the hexagon pattern are studied for different discharge parameters in dielectric barrier discharge system near the atmospheric pressure. The generating process and the movement of the microdischarge channels are observed. It is found that the wavelength of the hexagon decreases as the applied voltage increases. It is also dependent upon the gas gap and the gas pressure. The new filaments appear near the discharge boundary when the applied voltage increases slowly. The filaments at the outmost vertexes of hexagon move along the radial axis. The filaments on the side of hexagon move along axis parallel to the C2 axis, which has the least distance to those filaments. The discharge spots change into discharge stripes and finally into the spiral or target pattern when the applied voltage is increased further. Based on the experimental results and the force analysis, the confined potential, which exists in two dimensional coulomb crystals, is proposed to exist in the discharge domain.
