我们报告了叠加乘性噪声下向列液晶 (NLC) 中的交流驱动电对流 (EC)； EC 系统由施加电场中的 NLC 薄层（d = 10-100 μm）组成。交流驱动的行波 (TW) 是具有 Hopf 分岔的有吸引力的 EC 之一，弱电解质模型可以很好地解释这一点。在本文中，噪声引起的行波 (TW) 与交流驱动的行波 (TW) 进行了比较。此外，考虑一维和二维 EC 模式，讨论了 TW；它们揭示了交流场和噪声场对于 TW 的作用。
We report on ac-driven electroconvection (EC) in a nematic liquid crystal (NLC) under superposed multiplicative noise; the EC system consists of a thin layer (d = 10-100 μm) of an NLC in an applied electric field. Ac-driven traveling waves (TWs) have been one of attractive EC showing a Hopf bifurcation, which have been well explained by a weak-electrolyte model. In this paper, noise-induced traveling waves (TWs) are presented in comparison with ac-driven TWs. Moreover, considering one- and two-dimensional EC patterns, TWs are discussed; they reveal the roles of the ac and noise fields for TWs.
