摘要：目的:寻找具有生理病理意义的脉象特征,为脉象的识别开辟一个新的研究思路。方法:共收集337例样本,其中弦脉129例、平脉93例和滑脉115例,对这些样本的脉图进行谐波分析,并利用血液动力学原理来估算弦脉、滑脉和平脉的血液动力学参数波速和反射系数的特征。结果:弦脉的波速v落在v≥13.241 m/s的范围内,平脉的波速落在5.64≤v≤9.742 m/s范围内,滑脉的波速大多数落在4.3≤v≤10 m/s范围内;弦脉的反射系数R落在R≥0.75范围内,平脉的反射系数大多数落在0.4≤R≤0.7范围内,滑脉的反射系数大多数落在0.1Objective： To look for pulse features with physiological and pathological significance and open a new research clue on pulse recognition in TCM.Methods： 337 cases were collected,including 129 cases of wiry pulse,93 cases of plain pulse and 115 cases of slippery pulse.All of the pulse conditions were analyzed by harmonic analysis to evaluate the features of wave velocity and reflection coefficient of plain pulse,wiry pulse and slippery pulse on the basis of hemodynamic principles.Results： The range of wave velocity（v） of wiry pulse was v≥13.241 m/s,the plain pulse was 5.64≤v≤9.742 m/s,and the majority of slippery pulse was 4.3≤v≤10 m/s.The range of reflection coefficient（R） of wiry pulse was R≥0.75,the majority of plain pulse was 0.4≤R≤0.7,and the majority of slippery pulse was 0.1R≤0.45.Conclusion： There lies a law in the distribution of wave velocity and reflection coefficient of plain pulse,wiry pulse and slippery pulse,and the wave velocity and reflection coefficient has connection with the blood vessel elasticity,viscosity of blood,peripheral resistance and other physiological parameters,thus the wave velocity and reflection coefficient can be considered as features of pulse with physiological and pathological significance for distinguishing pulses.
