我们扩展了Ibañes等人提出的噪声诱导相变的机制。87，020601（2001）]的模式形成现象。与已知的纯噪声诱导的图案形成的机制相比，这种机制不是由集体效应放大的短时间不稳定性驱动的。通过调制平均场近似和数值模拟分析了这一现象。
We extend the mechanism for noise-induced phase transitions proposed by Ibañes et al. [Phys. Rev. Lett. 87, 020601 (2001)] to pattern formation phenomena. In contrast with known mechanisms for pure noise-induced pattern formation, this mechanism is not driven by a short-time instability amplified by collective effects. The phenomenon is analyzed by means of a modulated mean field approximation and numerical simulations.
