查询词典 AC

The numerical simulation result indicates that the condition of which generated APSGD is that the AC voltage frequency is 9kHz when the electrodes configuration is determinate and the sinusoidal peak-to-peak applied voltage is about 9kV. When the AC voltage frequency is about 1MHz, the discharge pattern of SDBD is filament discharge. This results is very important for the development of SDBD.
