The dielectric barrier discharge (DBD) at one atmospheric pressure is excitated in a configuration of two water electrodes by a repetitive nanosecond-pulse generator with 40 ns rise time and 70 ns duration. The DBD characteristic is studied by the measurement of DBD voltage and current, DBD images of long and nanosecond exposures. Especially, the discharge images taken by ICCD with 2 ns exposure time are used to study the temporal behaviour of the discharge development. The results indicate that the nanosecond-pulse discharge is uniform and stable with the water electrodes in atmospheric air and there is a secondary discharge. The homogeneous discharge starts from the central part of the discharge area and spreads radially outward.
