The photosensitive Belousov-Zhabotinsky (BZ) reaction was investigated on a double rectangular field composed of two rectangular routes, which was drawn using computer software and then projected using a liquid-crystal projector on a filter paper soaked with BZ solution. When two chemical waves were generated on the rectangular routes as the initial condition, the nature of the collision of the waves could be theoretically classified into four categories depending on the initial phase difference between the two waves and the aspect ratio of the rectangular routes. The experimental results were consistent with the features of the theoretical prediction. These results suggest that the feature of wave propagation characteristically develops depending on the geometry of the excitable fields.
在由两条矩形路径组成的双矩形区域上研究了光敏Belousov-Zhabotinsky(BZ)反应,该区域使用计算机软件绘制,然后通过液晶投影仪投射到浸泡有BZ溶液的滤纸上。当初始条件是在矩形路径上产生两个化学波时,根据两个波之间的初始相位差和矩形路径的纵横比,波的碰撞性质理论上可分为四类。实验结果与理论预测的特征一致。这些结果表明,波传播的特征取决于可激发场的几何形状。
