Resonance regions similar to the Arnol'd tongues found in single oscillator frequency locking are observed in experiments using a spatially extended periodically forced Belousov-Zhabotinsky system. We identify six distinct 2:1 subharmonic resonant patterns and describe them in terms of the position-dependent phase and magnitude of the oscillations. Some experimentally observed features are also found in numerical studies of a forced Brusselator reaction-diffusion model.
在使用空间扩展的周期性强迫贝洛索夫 - 扎博廷斯基系统的实验中，观察到了与单振荡器频率锁定中发现的阿诺德舌状区域类似的共振区域。我们识别出六种不同的2:1次谐波共振模式，并根据振荡的位置相关相位和幅度对它们进行描述。在强迫布鲁塞尔振子反应 - 扩散模型的数值研究中也发现了一些实验观察到的特征。
