摘要
本文提出了一种新的、含主动脉锥缩的体循环系统简单模型,此模型既保留了对血流分布惯性和动脉分布顺应性的模拟,又给出了解析形式的模型解,在此基础上进行了计算机模拟并对锥缩程度对主动脉血流动力学特性的影响问题进行了模拟研究。
A new hybrid paranmeter model of the systemic circulatory system including arterial taper is presented. The blood flow inertia and aortic compliance are simulated with distributed parameter model, and the analytic solution is obtained. Futhermore, the study of the aortic taper on the hy drodynamic performance was made with use of a computer simulation.
