Pattern formation in the Belousov-Zhabotinsky reaction experiments carried out by filling capillary glass tubes with catalyst-immobilized gel for the reaction is reported. Under unperturbed and oscillatory conditions, helicoidal waves appear spontaneously. Quantitative structural data of those helices are obtained by devising an optical tomography technique for extracting rotationally symmetric structures from time-lapse data. Space-time representation of the catalyst oxidation reveals wave transmission phenomenon that is studied further by numerical simulations of a reduced spatial model.
报道了通过在毛细管玻璃管中填充用于该反应的固定化催化剂凝胶进行的贝洛索夫-扎博廷斯基反应实验中的图案形成。在无扰动和振荡条件下，螺旋波自发出现。通过设计一种光学层析成像技术从延时数据中提取旋转对称结构，获得了这些螺旋的定量结构数据。催化剂氧化的时空表示揭示了波传播现象，通过简化空间模型的数值模拟对其进行了进一步研究。
