摘要：

A generalised stochastic Swift-Hohenberg equation is studied as an example of a pattern-forming system under the influence of fluctuations. An external fluctuation which is coupled to the order parameter is considered. Ordered structures appear in regions where the homogeneous situation is stable when only internal noise is present. These structures are analysed by studying the behavior of the mean value of the transmitted flux, its statistical variance and its linear relaxation time.
