Study of Modeling and Simulation of the Multi-branch Cardiovascular Systerm

应用功率键合图方法，建立了一种多分支心血管循环系统的计算机仿真模型，即描述心血管循环系统内血流动力学变量变化规律的状态方程。该仿真模型较为细致地刻画了心血管系统的生理特性，形成了较完整的人体心血管循环系统的数字计算模型，此模型可模拟心血管系统生理特性，给出相应的心血管动力学的仿真数据和波形，为进行心血管系统生理和病理等方面的计算机辅助数学和科研工作开辟了广阔途径。

By the Power Band Graph(PBG) method, this paper presents a computer simulation model of the multi-branch cardiovascular circulation system, which describes the blood fluid dynamic law in the cardiovacular system by the state equation. The model gives a minute description on physiological characters of cardiovascular circulation system (CVS). An integrate computer model on CVS has been established. The model can simulate physiological characters of cardiovascular circulation system and get the simulation data and the curves of CVS hemodynamics variables. The model can be used widely in the field of physiological system simulation study, medical study, and computer-aided instruction.
