摘　　要：在基于水电极的介质阻挡放电中,采用了带有9个相同且规则对称排列的正方形孔的玻璃板作为边界,得到了多个具有相同单元格结构的超四边形斑图,并对其时空动力学进行研究,分析了斑图形成的机制.结果表明每个单元斑图由边长不同的3个正方形子结构嵌套而成,第1个正方形子结构在小单元几何中心位置由4个小点组成,第2套子结构嵌套在第1个正方形子结构外围,由小正方形顶角和边上的点组成,靠近边界的12个点组成的正方形构成第3套子结构.用2个光电倍增管同时测量每套正方形子结构中任选2个点的时间相关性,得到每个正方形子结构中各个点的放电在时间上的一致性.本实验表明当气隙单元格的边长D与各单元格之间的间距d比值为2时,同样条件下,不同单元格之间的放电没有相互作用,放电斑图存在统一性,这对于小面积调制气隙的放电研究具有一定意义.In the dielectric barrier discharge(DBD)based on hydropower poles,glass plates with 9 identical square holes arranged in regular symmetry are used as the boundary to obtain a number of hyperquadrilateral speckled patterns with the same cell structure,and their spatio-temporal dynamics are studied to analyze the mechanism of speckled pattern formation.The results show that each unit pattern is nested by three square substructures with different side lengths,the first square substructure geometric center in small unit is composed of four with faint dot,second condom nested structure in the first square substructure is made up of small point on the side of a square apex Angle and the twelve point near the border of a square structure constitute the third condom.Two photomultiplier tubes were used to simultaneously measure the time correlation of any two points in each square substructure, and the time consistency of the discharge at each point in each square substructure was obtained.This experiment shows that when the ratio of the side length D of the air gap cell to the distance d between each cell is 2, under the same conditions, there is no interaction among the discharge of repeated cells, and there is uniformity in the discharge spot pattern, which is of certain significance for the discharge study of small area modulated air gap.
