摘要 According to clinical observations and model experiment,we have developed a theoretical mod- el and obtained its mathematical equations to investigate the displacement wave of the blood vessel.The waveform and its occurrence criterion have been obtained by using perturbation theory and numerical method. The present study suggests that the displacement wave is associated with the blood velocity waveform and the machanical behaviour of the blood vessel,but not with the pressure waveform.The clinical criterion is in agreement with the observations.
