| 摘 要： | 采用Greenberg-Hastings离散激发介质模型研究传导延迟对螺旋波动力学行为的影响.模拟结果表明:某些情况下,延迟对螺旋波动力学行为无影响;在适当参数下,可观察到螺旋波波长和波速的改变、呼吸螺旋波、多臂螺旋波以及螺旋波和反螺旋波共存现象,对产生这些现象的物理机制作了简要的解释.

| Abstract: | Effect of conduction delay on dynamical behavior of spiral waves is investigated in Greenberg-Hastings model.It shows that in some cases dynamical behavior of spiral waves is not impacted by conduction delay.Changes in wavelength and wave speed,breathing spiral wave,multi-armed spiral wave,coexistence of spiral wave and anti-spiral wave are observed.Physical mechanisms of these phenomena are briefly analyzed. |

| Keywords: | conduction delay Greenberg-Hastings model spiral waves |
