Abstract: The cardiovascular system is a complex coupling system, which consists of interacting parts constituting an indivisible integrity. In this paper, the E(t)-R model is adopted for the left and right ventricles, a newly-developed T-Y tube model with distributed parameters is adopted for the systemic arteries, and a newly-developed slightly asymmetric T tube model with distributed parameters is adopted for the pulmonary arteries. Then, the impulse response method and the flow conservation law are employed to simulate the dynamic coupling of the whole circulation in human body. Our computed theoretical results fit well to the available measured data.

Key words: dynamic coupling of the whole circulation, flow conservation, the impulse response method

摘要: 对左右心室均采用E( t )-R 模型,体动脉树采用T-Y管模型,肺动脉采用轻微非对称T管模型,利用脉冲响应法和流量守恒原理进行了全循环的动态耦合数值模拟,得到了与人体实验数据一致的结果。
