N2 - The plasma was generated by dielectric barrier discharge(DBD) in gas-liquid mixtures with aniline in an alkaline solution as the working media at atmospheric pressure. The influence of the plasma generating conditions, including the voltage and frequency of power supply, and discharge gap, on the discharge characteristics was evaluated by measuring the voltage-current waveforms, Lissajous figures and electrical and optical properties, such as the discharge power, transmitted charge, molecular vibrational and rotational temperature, and by theoretical analysis. The results show that the gas-phase DBD mechanism also accounts for the gas-liquid mixed DBD, except the major impact of the liquid-impedance on discharge. Its gas temperature varied in the range of 650~750 K and Na-peak was observed at 589 nm in the emission spectrum. The variations in power supply frequency resulted in a current resonance. The emission intensity, discharge power and transported charge were maximized at a frequency of 17.5 kHz in a discharge gap of 4 mm.
