摘　　要：Atmospheric pressure abnormal glow discharge （APAGD） was carried out simply with a transformer of 1 ： 500 driven by a alternating current with a frequency of 50 Hz. Typical stable discharge parameters, namely voltage of 400 V to 850 V and current of 60 mA to 110 mA were measured by oscillograph. Simulation of the discharge process suggested that the stable discharge was supported by the impedance from the secondary coil of the transformer, which offered a negative feedback to prevent the discharge from turning into an arc. An interpretation was given for the oscillogram of the sinuous discharge current and square voltage. Furthermore, the electron temperature and electron density averaged in the discharge channel of APAGD were estimated.Atmospheric pressure abnormal glow discharge （APAGD） was carried out simply with a transformer of 1 ： 500 driven by a alternating current with a frequency of 50 Hz.
