摘　　要：基于流体力学理论推导了人体动脉血管血流动力学模型。依据所得动力学模型,应用相似理论建立了一个RLC等效电路模型来模拟血液在动脉血管中的流动。推导此等效电路模型的传递函数,确定了主要特征参量,对动脉血管的血压、血流变化规律进行了仿真,获得了波形曲线。分析得到动脉血管血液流阻增大时,u o、I的变化即可反映血压、血流的相应变化。这可为相关血管、血压疾病的预防、临床诊断和治疗提供一定的技术帮助。Hemodynamic model of human arteries is deduced based on hydrodynamics and a RLC equivalent-circuit model is presented using similarity theory.Based on the equivalent-circuit model,the transfer function and the chief characteristics parameters were obtained,and the change laws of blood pressure,flood flow were simulated.The simulation showed that with arterial blood flow resistance increasing,changes of uo, I can reflect the corresponding changes of blood pressure and blood flow.It may provide some technical help for prevention,clinical diagnosis,treatment of correlative vascular disease,and blood disease.
