通过对受迫反应扩散系统的多尺度分析，导出振幅方程，解释了二氧化氯-碘-丙二酸体系中螺旋波的存在及其光致时空行为。当光照明强度被调制时，观察到螺旋的呼吸，其中呼吸周期与强迫周期相同。我们还导出了周期照明时螺旋波分裂和抑制的条件。数值模拟与我们的分析处理吻合得很好。
Based on a multiple scale analysis of a forced reaction-diffusion system leading to amplitude equations, we explain the existence of spiral wave and its photo-induced spatiotemporal behavior in chlorine dioxide-iodine-malonic acid system. When the photo-illumination intensity is modulated, breathing of spiral is observed in which the period of breathing is identical to the period of forcing. We have also derived the condition for breakup and suppression of spiral wave by periodic illumination. The numerical simulations agree well with our analytical treatment.
