Ferric ions catalyze the oxidation of malonate by bromate in acid solution, sometimes at a spatially uniform, steady rate, but sometimes in a self-regenerating three-dimensional wave which resembles a rotating scroll, often with its axis closed in a ring. In cross section perpendicular to the axis, one sees an involute spiral emerging from a thin cylindrical core. This "dissipative structure" organizes reaction stages periodically in space and time everywhere except along its rotation axis, which may therefore be a thermodynamically unique locus.
三价铁离子在酸性溶液中能催化溴酸盐氧化丙二酸，此时其氧化速率有时是空间均匀、稳定的，有时则会呈现出自我再生的三维波动，这种波动类似于旋转的漩涡，其轴常常呈环形封闭。在垂直于轴的横截面上，可以看到一条从细圆柱核中伸出的渐开线螺旋。这种“耗散结构”在空间和时间上将反应阶段有规律地组织起来，除了在其旋转轴上之外，无处不在，因此旋转轴可能是一个热力学上独特的位置。
