The collision of circular chemical waves in an excitable medium, the Belousov-Zhabotinskii reaction, leads to characteristic cusplike structures. The high curvatures of these structures are especially suitable for experimentally verifying the predicted proportionality between the velocity and the shape of traveling waves. A computerized spectrophotometric video technique with microscopic resolution was used to determine the proportionality factor (2 x 10(-5) square centimeter per second), which in this case is the diffusion coefficient of the autocatalytic species of the reaction system. A numerical calculation of the spatiotemporal evolution of the cusp structure is in good agreement with the experimental observations.
在兴奋介质中圆形化学波的碰撞会导致特征状的峰状结构。这些结构的高曲率特别适合于实验验证预测的行波速度和形状之间的比例关系。使用具有微观分辨率的计算机化分光光度视频技术来确定比例因子（2 x 10(-5) 平方厘米每秒），在这种情况下，该比例因子是反应系统的自催化物质的扩散系数。对峰状结构的时空演化的数值计算与实验观察结果非常吻合。
