中文摘要：

为了减弱在斑图形成时实验条件的限制,获得同一斑图的多种形成途径,利用双水电极介质阻挡放电装置,在空气/氩气混合气体放电中,观察到了超六边形斑图的4种形成途径.在不同气压和氩气含量下,研究了4种斑图包括不规则六边形斑图、六边形斑图、四边形斑图和四六边形共存斑图到超六边形斑图的演化.实验发现随气压及氩气含量的变化,它们向超六边形斑图演化时的出现范围由大到小依次是六边形斑图、四六边形共存斑图、不规则六边形斑图和四边形斑图.

英文摘要：

In order to weaken the limits of experimental conditions when forming patterns,it is necessary to find a variety of approaches to form the same pattern,four approaches of forming hexagonal superlattice pattern were obtained in dielectric barrier discharge in the mixture of air/argon by using a device with two water electrodes.Under different pressures and argon contents,the evolutions from four kinds of patterns concluding irregular hexagon,hexagon,square and coexistence of square and hexagon to hexagonal superlattice pattern were studied.With the changes of pressures and argon contents,it is found that the appearance ranges from big to small when they evolve into hexagonal superlattice pattern are hexagon,coexistence of square and hexagon,irregular hexagon and square pattern.
