在用氦气稀释的丁烷和氧气的贫混合物（Le = 3.0）预混火焰中观察到扩散热高刘易斯数（Le）气相振荡器。这个反应扩散系统同时表现出传播的径向脉动和旋转的螺旋波，这可能类似于在其他可激发介质（例如Belousov-Zhabotinsky反应）中观察到的情况。
A diffusive‐thermal high Lewis number (Le) gas‐phase oscillator has been observed in premixed flames using a lean mixture of butane and oxygen diluted with helium (Le≊3.0). This reactive‐diffusive system exhibits both propagating radial pulsations and rotating spiral waves perhaps analogous to those observed in other excitable media such as the Belousov–Zhabotinsky reaction.
