在 0 摄氏度到 8 摄氏度之间进行的无搅拌 Belousov-Zhabotinsky 振荡反应中报告了复杂的周期性和非周期性行为。确定了遵循 Ruelle-Takens-Newhouse (RTN) 场景的混乱路线。因此，温度对化学动力学、扩散和对流之间耦合的影响似乎是观察到的 RTN 场景的原因。在这封信中，我们证明温度是序列 period-1 --> 准周期性 --> 混沌的分岔参数。 (C) 2001 Elsevier Science B.V. 保留所有权利。
Complex periodic and aperiodic behaviours are reported in an unstirred Belousov-Zhabotinsky oscillatory reaction performed at temperatures varying between 0 degreesC and 8 degreesC. A route to chaos following a Ruelle-Takens-Newhouse (RTN) scenario is identified. Thus, temperature effects on the coupling between chemical kinetics, diffusion and convection, seem to be responsible for the observed RTN scenario. In this Letter we demonstrate that the temperature is a bifurcation parameter for the sequence period-1 --> quasiperiodicity --> chaos. (C) 2001 Elsevier Science B.V. All rights reserved.
