摘　　要：提出心血管循环系统的血流动力学功率键合图模型 ,应用状态空间方法和计算机仿真技术 ,对一个简化的心血管循环系统模型进行了仿真研究 ,所得仿真数据同基本的生理规律具有较好的符合性 ,证明了功率键合图这种系统动力学建模方法在循环系统仿真中具有良好的可行性和有效性 。We presented a Power Band Graph(PBG) model to simulate blood fluid dynamics of the cardiovascular circulation system. The PBG modeling method described the blood fluid dynamic law in the circulation system by the state equation. Besides, the PBG modeling method was used to realize modeling on the human circulation system and conduct a simulation study on a simplified cardiovascular system model. The results demonstrated that the PBG method was quite effective and practicable. The study provided a simple and unitary simulation modeling method for cardiovascular system simulation.
