位置扰动对激发介质中螺旋波动力学行为的影响
Effect of Position Perturbation for Spiral Waves in Excitable Media
摘要
Abstract
Based on the Greenberg-Hastings cellular automata model, the effect of the position perturbation for the spiral waves in excitable media is studied.The amplitude of the position perturbation represents the interaction distance between cells.The computer simulation results show that the position perturbations with different amplitudes are added into the system after the stable spiral wave is formed,and the stability of spiral wave meanders is related to the range of the position perturbation of the cells.Different ranges of the position perturbation will result in two different changes of the stable waves.New stable waves are formed or disappeared after meanders.The two types meandering behavior are observed,and the mechanism underlying these phenomena are analyzed.关键词
