我们描述了对称破缺静止图样的实验观察。这些模式被解释为在单相等温化学反应体系中图灵型结构的第一个明确证据。在充满水凝胶的开放式空间反应器中进行了多功能亚氯酸盐-碘-丙二酸反应的实验。讨论了包含对称性破缺和非对称性破缺立态存在范围的相图。
We describe experimental observations of symmetry breaking stationary patterns. These patterns are interpreted as the first unambiguous evidence of Turing-type structures in a single-phase isothermal chemical reaction system. Experiments are conducted with the versatile chlorite-iodide-malonic acid reaction in open spatial reactors filled with hydrogel. A phase diagram gathering the domain of existence of symmetry breaking and no-symmetry breaking standing patterns is discussed.
