| 摘 要： | 为了揭示和研究人体脉搏系统的作用机理,文章从一种新的角度———系统分析和信号处理的角度建立了人体脉搏系统传递函数模型,获得脉搏系统传递函数的一般形式,结果表明传递函数只有极点而没有零点。根据脉象信号的实验测量数据对模型参数进行了估计。并运用此模型在计算机上成功地模拟了人体四种脉象信号,仿真结果与实际结果相符。

| Abstract: | Pulse-feeling is one of the most important diagnostic methods in Traditional Chinese Medicine.In order to re veal the mechanism of Human Pulse System(HPS),the transfer function model of the HPS is set up and studied with the method of system analysis and signal processing.The general form of the HPS transfer function is obtained,which is an all-poles transfer function,namely the transfer function has only poles but not zero points.The model parameters are estimated with the clinical data of the human pulse condition signals.The four kinds of the pulse signals are simulated by using the pulse signal digital model.The simulation results show that the basic characteristics of the simulating pulse signals are in accord with that of the clinical pulse signals. |
