Experiments on a bistable chemical reaction in a continuously fed thin gel layer reveal a new type of spatiotemporal pattern, one in which fronts propagate at a constant speed until they reach a critical separation (typically 0.4 millimeter) and stop. The resulting asymptotic state is a highly irregular stationary pattern that contrasts with the regular patterns such as hexagons, squares, and stripes that have been observed in many nonequilibrium systems. The observed patterns are initiated by a finite amplitude perturbation rather than through spontaneous symmetry breaking.
在连续进料的薄凝胶层中的双稳化学反应实验中，揭示了一种新型的时空模式，其中前沿以恒定速度传播，直到达到临界分离（通常为 0.4 毫米）并停止。由此产生的渐近状态是一种高度不规则的稳定模式，与在许多非平衡系统中观察到的规则模式（如六边形、正方形和条纹）形成对比。观察到的模式是由有限振幅的微扰而不是通过自发对称破缺引发的。
