研究了在0.7MH2 O2-0.3MH2 SO4溶液中，两个铂电极上还原电流同步振荡的机理。如果工作电极和参考电极之间的距离足够大，则即使在两个铂工作电极彼此相距很远的情况下也会发生同步。即使当其中一个工作电极用导电碳盒与其他电极分开时，也会发生同步。这些结果清楚地表明，同步不是由质量输运引起的，而是由电相互作用引起的。结果表明，其中一个振荡系统中的电流振荡通过欧姆降的振荡引起相邻振荡系统的真电极电位的振荡，从而导致同步。
The mechanism of synchronous oscillations found for reduction currents on two Pt electrodes in 0.7 M H 2 O 2 -0.3 M H 2 SO 4 has been investigated. Synchronization occurs even when the two Pt working electrodes are far apart from each other if the distance between the working and reference electrodes is large enough. The synchronization also occurs even when one of the working electrodes is separated from the other electrodes with an electrically conductive carbon box. These results clearly indicate that the synchronization is not induced by mass transport but by electrical interaction. It is concluded that the current oscillation in one of the two oscillation systems causes an oscil ation in the true electrode potential for the neighboring oscillation system through the oscillation of the ohmic drop in the solution, which leads to the synchronization.
