摘要
建立了一个二维非线性模型来模拟心脏活动的动力学行为 ,并利用解析和数值的方法对该模型进行了深入的研究 .这个模型可以演示实际心脏系统表现出来的锁相行为和混沌行为 .模型中存在的禁区对系统的稳定性有极为重要的影响 ,在这个系统中可找到由周期吸引子与禁区边界碰撞所导致的
This paper proposes a two dimensional nolinear model to simulate the kinetics of heart and studies the characteristics of the model both analytically and numerically. It is found that it could illustrate the phase\|locked and choastic phenomenas in heart. The existence of the forbidden zone has a great influence on the stability of the system. Type\|V intermittency induced by a collision between a periodic attractor and the boundary of the 'forbidden zone' has been found.
