氩气介质阻挡放电中的六边形斑图和条纹斑图

Hexagon pattern and stripe pattern in dielectric barrier discharges in Argon

采用水电极介质阻挡放电系统,在氩气中高于辉光放电电压的情况下观察到了稳定的六边形斑图及流动的条纹斑图,并利用其傅立叶频谱进行了分析。这种斑图是在均匀的辉光背景下产生的,为典型的图灵斑图。

By using DBDS device with two water electrodes, stable hexagon pattern and drifting tripe pattern are obtained when the voltage exceeds that of the glow discharge in Argon. These patterns are analyzed with their Fourier spectrums. They origin from the glow discharge. They are typical Turing patterns.
