摘　　要：由非创伤性测量获得的脉搏波可由若干个高斯函数合成,提出一种得到最优高斯拟合脉搏波信号的方法.首先提取能反映人体心血管系统生理病理信息的一些特征参数,然后选择其中的一个或多个特征参数作为评价高斯拟合效果的标准,最后依据这些标准得到最优的高斯拟合脉搏波信号.由于依据该方法得到的拟合脉搏波信号的一些重要特征参数与实测脉搏波信号最为接近,因而更能真实地反映人体心血管系统的生理病理状态.Pulse wave obtained by noninvasive method can be synthesized by several Gauss functions, so a kind of method to get the best Gaussian fitting pulse wave signal was proposed. Firstly, some characteristic parameters reflecting the physiological and pathological information of human cardiovascular system were extracted. Then, one or more characteristic parameters were chosen as the standard for evaluating the effect of Gaussian fitting. Finally, a best Gaussian fitting pulse wave signal was acquired based on these standard. Because some important characteristic parameters of the fitting pulse wave signal obtained by this method are most closed to these of the measured pulse wave signal, reflects the physiological and pathological state of the human cardiovascular system thus it more ac-curately.
