摘要: In this paper, the method of Spatial Fourier Transform has been used to investigate pattern formation dynamics in a dielectric barrier discharge (DBD) system. With method, patterns formed DBD system can be transformed into smooth frequency spectrum. The constitution analyzed. our experiment mixed gas 96% Ar and 4% air at 0.9 atm is as working gas. experimental results show that with increasing applied voltage undergoes scenario: stochastic filaments, hexagon pattern, square honeycomb structure. different kinds were space by two-dimension Transform. spectra given analyzed paper. It was found correspond spectrum, furthermore, better stability clearer Therefore, transition procedure from one another also studied Consequently, research
