摘要: The concentric superlattice pattern with three sub-lattices is observed in the dielectric barrier discharge air/argon for first time. Its spatiotemporal structure investigated by an intensified charge-coupled device shows that it interleaving of different sub-lattices, which are concentric-ring, concentric-framework, and concentric-dot, respectively. images single-frame indicate concentric-ring concentric-framework composed individual filaments. By using optical emission spectrum method, found plasma parameters concentric-dot from those concentric-framework. dynamics dependent upon effective field distribution wall charges applied field.
