【Abstract】 The coupling action and synchronization of the current oscillation for two copper wire anodes in phosphoric acid solution are studied. The potential between the working and reference electrodes and the interval between two copper wires are adjusted in the experiment. The periods and amplitudes of current oscillation are strongly dependent on the potential and the electrode interval. The differences between the signals of the two electrodes lead coupling action, make waves modulation and lead more complex oscillation behavior. Waveforms depend on the potential and coupling strength. The k/n phaselockand quasiperiod synchronization of current oscillation for different electrodes are found. Strongly coupling will tend to lead the synchronization of current oscillation for different electrodes. With the increase of the interval between the copper wires, synchronization is hard to be found. The coupling mechanism and emergence of special oscillation are analyzed and discussed.更多还原
