研究了含铁催化剂的溴酸盐-1，4-环己二酮封闭反应体系中的一种反常的复苏波和振荡现象。改变1，4-环己二酮和溴酸盐初始浓度的实验表明，在反应条件的狭窄区域内自发地出现复苏振荡。对一个由22个反应和15个组分组成的动力学模型进行了数值计算，以了解导致这种奇异动力学的潜在机制。这些模拟能够再现实验观察到的复苏振荡的定性性质，但还不能定量性质。
An unusual phenomenon of revival waves and oscillations is studied in a closed bromate‐1,4‐cyclohexanedione reaction system containing ferroin catalyst. Experiments with varying initial 1,4‐cyclohexanedione and bromate concentrations show that revival oscillations spontaneously emerge at a narrow area of the reaction conditions. Numerical calculations of a kinetic model consisting of 22 reactions and 15 species are employed to gain understanding of the underlying mechanism contributing to such an exotic dynamics. The simulations are able to reproduce the qualitative, but not yet quantitative properties of the experimentally observed revival oscillations.
