We study a phenomenon of stochastic generation of waveform patterns for reaction-diffusion systems in the Turing stability zone where the homogeneous equilibrium is a single attractor. In this analysis, we use a distributed variant of the Selkov glycolytic model with diffusion and random forcing. It is shown that in the Turing stability zone, random disturbances can induce a diversity of metastable spatial patterns with different waveforms. We carry out the parametric analysis of statistical characteristics of evolution of these patterns, and reveal the dominant patterns in the stochastic flow of mixed spatial structures.
我们研究了在图灵稳定区域内反应扩散系统波形模式的随机生成现象，其中均匀平衡态是唯一吸引子。在此分析中，我们使用了具有扩散和随机强迫的塞尔科夫糖酵解模型的分布式变体。结果表明，在图灵稳定区域内，随机扰动可诱导出具有不同波形的多种亚稳空间模式。我们对这些模式演化的统计特征进行了参数分析，并揭示了混合空间结构随机流中的主导模式。
