The quantitative structure of the core of the spiral-shaped traveling wave of chemical activity appearing in a thin excitable layer of the Belousov-Zhabotinskii reaction, in which the oxidation and decarboxylation of malonic acid by bromate ions is catalyzed by ferroin, was analyzed experimentally. Light absorption by ferroin as the reduced reaction catalyst and indicator was measured by means of a video-and computer-based two-dimensional spectrophotometer with 10-micrometer spatial, 2-second temporal, and 256-digital units intensity resolution. The spiral core is a singular site (diameter, 30 micrometers or less) at which intensity modulations due to ferroin-ferriin distributions are at least ten times smaller than in the surrounding area of spiral propagation. Archimedian spirals were fitted to isoconcentration lines.
实验分析了贝尔洛索夫-扎鲍廷斯基反应薄激发层中出现的螺旋形传播行波的核心的定量结构，其中丙二酸的氧化和脱羧作用由重铬酸钾离子催化，通过具有 10 微米空间、2 秒时间和 256 位数字强度分辨率的基于视频和计算机的二维分光光度计测量了作为还原反应催化剂和指示剂的铁啉的光吸收。螺旋核心是一个奇异点（直径小于或等于 30 微米），铁啉-铁啉分布的强度调制至少比螺旋传播的周围区域小十倍。阿基米德螺旋线拟合等浓度线。
