在铈催化的Belousov-Zhabotinsky反应中，在广泛的试剂浓度范围内对化学波的稳定性进行了系统的测量。的临界半径和宽度的自催化剂带中的波阵面进行了测量，以验证计算预测的参数区域的波端出现的横向不稳定性。的数据产生的实验参数集的发病不稳定的行为，并允许讨论不同的理论描述的临界曲率。
Systematic measurements of the stability of chemical waves were carried out over a wide range of reagent concentrations in the cerium‐catalyzed Belousov–Zhabotinsky reaction. The critical radius and the width of the autocatalyst band in the wave fronts were measured in order to verify the computed prediction for the region of parameters where lateral instabilities of the wave ends appear. The data yield an experimental parameter set for the onset of unstable behavior and allow a discussion about different theoretical descriptions of the critical curvature.
