【摘要】：本实验首次在双水电极介质阻挡放电装置中获得暗环白眼超四边形斑图.该斑图的每个四边形晶胞内都包含一个由黑色圆环围绕的中心亮点.这种黑色圆环围绕中心亮点的结构类似于白眼晶胞,称为暗环白眼.利用高速照相机研究暗环白眼超四边形斑图的时空结构.结果发现,暗环白眼超四边形斑图由4套不同的子结构相互嵌套而成,在每半个外加电压周期内,子结构的放电顺序依次为:中心亮点-亮点晕-顶点四边形-顶点连线.其中,暗环白眼是由中心亮点和周围的环形不放电区域组成的.利用壁电荷理论解释了暗环白眼超四边形斑图的形成机制和暗环的形成原因.
[Abstract]:For the first time in this experiment, a dark ring white eye hyperquadrilateral pattern was obtained in a double water electrode dielectric barrier discharge device. Each quadrilateral cell of the pattern contains a central bright spot surrounded by a black ring, which is surrounded by a black ring. The structure of the central bright spot is similar to that of the white eye cell. Using a high speed camera to study the space-time structure of the dark ring white eye hyperquadrilateral pattern, it is found that the dark ring white eye hyperquadrilateral pattern consists of four sets of different substructures nested from each other in every half of the applied voltage period. The discharge order of the substructure is as follows: central bright spot-bright spot halo-vertex quadrilateral-vertex line. The dark ring white eye is composed of the center bright spot and the annular non-discharge region around it. The formation mechanism of the dark ring white eye hyperquadrilateral pattern and the cause of the dark ring formation are explained by the wall charge theory.
