我们发现，退火后的单轴压缩会影响微皱模式及其在机械扰动下的稳定性，而微皱模式最初表现为复杂的条纹相。与未退火的情况相比，我们观察到卸载压应力后的特征准双轴条纹图案，这表明原始图案的恢复。此外，另一个不同方向的加载-卸载循环会引起调制模式的变化，表明该模式对机械扰动不再稳定。
We find that annealing followed by uniaxial compression affects the microwrinkle pattern, which originally shows a complex stripe phase, and its stability to mechanical perturbation. We observe a characteristic quasi-biaxial stripe pattern after unloading compressive stress in contrast to the case without annealing, which shows the retrieval of the original pattern. Moreover, another loading-unloading cycle in a different direction induces a change in the modulated pattern, indicating that the pattern is no longer stable to mechanical perturbations.
