The Belousov-Zhabotinsky (BZ) reaction was investigated to elucidate features of oscillations depending on the applied electrical potential, E. A cation-exchange resin bead loaded with the catalyst of the BZ reaction was placed on a platinum plate as a working electrode and then E was applied. We found that global oscillations (GO) and a reduced state coexisted on the bead at a negative value of E and that the source point of GO changed depending on E. The thickness of the reduced state was determined by a yellow colored region which corresponded to the distribution of Br. The present studies suggest that the distribution of the inhibitor, Br, which is produced from Br, plays an important role in the existence of the reduced state and GO, and the source point of GO.
研究了别洛索夫-扎鲍廷斯基（BZ）反应，以阐明随施加的电势能 E 变化的振荡特征。将负载 BZ 反应催化剂的阳离子交换树脂珠放置在铂板上作为工作电极，然后施加 E。我们发现，在 E 为负值时，珠上存在整体振荡（GO）和还原态共存，并且 GO 的源点随 E 而变化。还原态的厚度由对应 Br 分布的黄色区域确定。本研究表明，抑制剂 Br 的分布（由 Br 产生）在还原态和 GO 的存在以及 GO 的源点中起着重要作用。
