研究了亚铁试剂催化的Belousov-Zhabotinsky反应中化学波的Marangoni效应。本研究的主要目的是了解的机制，大波，一个加速化学波涉及表面张力驱动的流体运动。用Wilhelmy方法测量了由化学波引起的表面张力的时空变化。由于溴丙二酸的浓度变化，观察到从常规触发波到大的波的过渡。溴丙二酸的强表面活性，这是负责的过渡也被观察到。它通过马兰戈尼效应导致了大浪的加速。
The Marangoni effects on chemical waves in the ferroin-catalyzed Belousov-Zhabotinsky reaction were studied. The main purpose of the present study was to understand the mechanism of the big wave, an accelerative chemical wave involving surface-tension-driven fluid motions. Spatiotemporal variations of surface tension caused by a chemical wave were measured using the Wilhelmy method. The transition from conventional trigger waves to big waves, due to a concentration change of bromomalonic acid, was observed. The strong surface activity of the bromomalonic acid which was responsible for the transition was also observed. It led to an acceleration of the big waves through the Marangoni effect.
