Abstract

Experimental evidence of the use of a circularly polarized electric field to control the spiral turbulence in a reaction-diffusion system is presented. The spiral turbulence obtained in the Belousov-Zhabotinsky reaction is shown to be forced into ordered stable spiral waves or "targetlike" waves by a circularly polarized electric field with appropriate frequency and intensity. An Arnold's-tongue-shaped control phase diagram is obtained, illustrating the resonance essence of the control.

摘要

本文给出了利用圆偏振电场控制反应扩散系统中螺旋湍流的实验证据。结果表明，在Belousov-Zhabotinsky反应中获得的螺旋湍流可被具有适当频率和强度的圆偏振电场强迫转变为有序的稳定螺旋波或“靶形”波。得到了一个阿诺德舌形控制相图，阐明了该控制的共振本质。
