We investigated the response of dissipative structures of electroconvections (ECs) to external noise. Due to the intrinsic mechanisms of ECs, noise-induced thresholds and wavelengths were completely different from one another. The response strongly depended on the characteristic of noise (e.g., white or colorednoises). In particular, our results of the wavelength variations (of chevrons in high frequency region) are quite useful for fabricating modulated polymer surfaces by means of ECs.

我们研究了电对流（EC）耗散结构对外部噪声的响应。由于EC的内在机制，噪声引起的阈值和波长彼此完全不同。响应很大程度上取决于噪声的特征（例如白色或有色噪声）。特别是，我们的波长变化（高频区域中的 V 形）结果对于通过 EC 制造调制聚合物表面非常有用。
