%X The relations between the resistance of the plasma channel of pulsed discharge in water and the circuit parameters are discussed; the laws of the channel resistance changed with capacitance, initial voltage and electrode gap width are presented. On the other hand, the relations between the peak pressure of shock wave and the circuit parameters are investigated, and the power spectrum of the shock wave is analysed. The results show that the frequency of the bandwidth of the acoustic radiation ranges from scores of hertz to scores of kilohertz, it covers all the frequencies of underwater sound equipment, and has high acoustic radiation power in low frequency band. Hence it is an ideal underwater sound source.
