摘要
本文利用网络综合方法，根据升主动脉输入阻抗的三阶数学表达式，建立了正常人血液体循环的集中参数模型。该模型既具有十分逼近生理的阻抗特性，又可以在循环模拟装置上实现，而且结构简单。
By means of network synthesis, a lumped parameter model of systemic blood circulation in normal people was developed according to the three order mathematical expression of the input impedance in ascending aorta. The model provided satisfactory impedance characteristics, which approximated the physiological case closely. Also it could be realized by a mechanical mock loop with simple structure. This showed that the method of network synthesis might be used as a feasible approach to the modeling of the blood circulation system.
