螺旋波动力学得实验研究

This research project is for study spiral dynamics and spiral turbulence. The project has both theoretical value and application impact. From basic research point of view, how to describe a spatiotemperal chaos system is a new challenge for nonlinear scientists. The study of transitions from ordered spiral pattern to spiral turbulence is a point of break through in this field. From application point of view, recent experiments from cardiologists confirms that certain heart diseases is due to the spiral breakup in the electrocadiac single in heart. Studying the general route of spiral breakup may give the cardiologist new hints to prevent and control heart diseases. During the last year, our laboratory has make news progress in this field of research. Including systematically study of the rules of spiral tip movement; discovering a new method of controlling spiral waves; and discover the stochastic resonance of spiral waves.

在反应扩散系统中研究螺旋波斑图的动力学性质。研究重点是螺旋波向时空混沌相变的不同机制，找出控制螺旋波免于失稳的有效方法，探索在可激发系统消除螺旋波的途径。.
