在离散化学振荡系统中研究了化学振荡器之间的耦合特性，该系统由负载铁蛋白的阳离子交换小球浸泡在Belousov-Zabotinskii反应溶液中实现。得到了作为振子固有频率和振子间距d的函数的耦合态相图。发现这种同步并不是由于较慢的振荡器被较快的振荡器简单地夹带。振荡器之间发生的各种夹带取决于非耦合状态下的固有频率的比率。在频率比为n/1的稳定耦合区域的边界处发现了混沌行为，其中n为整数。此外，还研究了外部扰动对耦合的影响。在He-Ne激光照射下，产生了不规则振荡，这种振荡强烈地依赖于振荡器在照射开始时的相位。这种不正常的行为是地方性的。
The properties of the coupling between chemical oscillators were studied in the discrete chemical oscillation system which was realized by immersing cation exchange beads loaded with ferroin in the Belousov–Zabotinskii reaction solution. A phase diagram of coupling states was obtained as a function of natural frequencies of oscillators and the distance d between oscillators. The synchronization was found not to be attributed to a simple entrainment of the slower oscillator by the faster one. Various entrainments between oscillators occurred depending on ratios of natural frequencies in the uncoupled state. A chaotic behavior was found at the boundary between stably coupled regions with frequency ratios of n/1 where n is an integer. Furthermore, effects of external perturbation on the coupling were investigated. Irregular oscillations were induced by illumination with a He–Ne laser light, which strongly depended on the phase of oscillator at the beginning of illumination. Such irregular behaviors were loca...
