The square pattern has been obtained for the first time in dielectric barrier ar / air discharge at atmospheric pressure by using the double water electrodes and its spatio - temporal dynamics is measured by optical method . the phase diagram of pattern types as a function of air concentration and applied voltage by fixing other parameters is given 本论文采用特殊设计的双水电极介质阻挡放电实验装置，首次在氩气与空气的混合气体中获得了大气压常温下的稳定正方网格斑图，并对其进行了时空动力学测量。
