【Abstract】 Stable patterns were obtained in dielectric barrier discharge in the gas mixture of Argon and air by using special water electrode device.The patterns were transformed into Fourier space by 2D FFT.The spectrums of patterns were analyzed and the correlative operations of patterns were done.As a result,the structures of patterns were hexagon,hexagon-like and irregular respectively.更多还原
