The light-induced collapse of a pair of spiral waves was studied in a chemically active medium based on the photosensitive Ru(bpy)(3)-catalyzed Belousov-Zhabotinsky reaction. Spiral waves annihilate only if the light intensity is increased in proper phase relative to the spiral waves' rotation. Otherwise, the distance between spiral wave cores increases and the pair survives. Computer simulations reveal the mechanism which forces the spiral waves to collide and annihilate. It is based on the shift of a single spiral wave upon an instantaneous decrease of excitability of the medium. (c) 1996 American Institute of Physics.
基于光敏Ru(bpy)(3)催化的贝洛索夫-扎博京斯基反应，在化学活性介质中研究了光诱导的一对螺旋波的坍缩。只有当光强度相对于螺旋波的旋转在适当相位增加时，螺旋波才会湮灭。否则，螺旋波核心之间的距离会增加，这对螺旋波会继续存在。计算机模拟揭示了迫使螺旋波碰撞并湮灭的机制。它基于介质兴奋性瞬间降低时单个螺旋波的移动。(c) 1996美国物理研究所。
