摘　　要：根据生物流体系统同工程流体系统所具有的相似性，将功率键合图建模方法应用于人体血液循环系统的计算机仿真当中，对一个简化的人体血液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符合较好。The power band graph (PBG) method is a convenient system dynamic modeling method, which is used successfully in fluid system dynamic character simulation. As there are many similarities to a great extent between biological fluid system and engineering fluid system according to fluid dynamic theory, this paper uses the PBG approach in the computer simulation of human blood circulation system,and has completed a modeling and simulation study on a simplified human blood circulation system model. The results of the simulation are in good agreement with the basic physiological law. The study provides a simple and unitary simulation modeling method for physiologic medical simulation.
