摘要：

We present results of experimental and numerical work on a Taylor-Couette system with imposed axial flow. When the base flow is convectively unstable, macroscopic patterns of travelling Taylor vortices are observed downstream of the inlet. Numerical integration of the stochastic complex Ginzburg-Landau equation indicates that these patterns arise from the spatial amplification of microscopic noise. The noise leads to an irregular phase in the vortex pattern. In contrast, the phase is very regular when the base flow is absolutely unstable.
