Almost 30 years have passed since the discovery of concentric (target) and spiral waves in the spatially extended Belousov-Zhabotinsky (BZ) reaction. Since then, rotating spirals and target waves have been observed in a variety of physical, chemical, and biological reaction-diffusion systems. All of these waves propagate out from the spiral center or pacemaker. We report observations of inwardly rotating spirals found in the BZ system dispersed in water droplets of a water-in-oil microemulsion. These "antispirals" were also generated in computer simulations.
自空间扩展的贝洛索夫-扎博廷斯基(BZ)反应中发现同心(靶形)波和螺旋波以来,已过去近30年。从那时起,在各种物理、化学和生物反应扩散系统中都观察到了旋转螺旋波和靶形波。所有这些波都从螺旋中心或起搏器向外传播。我们报告了在分散于油包水微乳液水滴中的BZ系统中发现的向内旋转螺旋波的观测结果。这些“反螺旋波”也在计算机模拟中产生。
