Horizontally propagating chemical fronts are studied in a thin solution layer of the acid-catalyzed chlorite-tetrathionate reaction. Unusual cellular patterns develop when significant amount of autocatalyst is bound to polyelectrolyte with low mobility: both oscillatory and stationary patterns evolve as a result of the interaction between the reaction front and the superposed gravity current. The concentration of the polyelectrolyte regulating the velocity of front propagation serves as a bifurcation parameter for switching between the two basic patterns.
在酸催化的亚氯酸盐-四硫代硫酸盐反应的薄溶液层中研究了水平传播的化学前沿。当大量的自动催化剂与低迁移率的聚电解质结合时，会形成异常的细胞模式：由于反应前沿和叠加重力流之间的相互作用，会产生振荡和固定模式。调节前沿传播速度的聚电解质浓度是在两种基本模式之间切换的分岔参数。
