DISPLACEMENT WAVE OF THE BLOOD VESSEL-A MECHANICAL MODEL
-
摘要: 本文在临床观察和模型实验的基础上提出了血管位移波的力学模型,并归结出了位移波的控制方程。应用摄动理论和数值方法,求得了位移波的波形和位移波产生的判别准则。从中我们发现,位移波仅和血流的脉动速度及血管壁力学特性有关,而和压力波无直接关系。最后本文还给出了一个适用于临床的位移波发生判别准则,实验发现它和临床观察是相符合的。Abstract: According to the clinical observations and model experiment, we have de-veloped a theoretical model and its mathemational equations to investigate the displacement wave of the blood vessel. The wave performance and its criterion of occurrence have been obtained by using perturbation theory and numerical method. The present study suggests that the displacement wave is governed by the blood velocity wave performance and the machanical behavior of the blood vessel, not the pressure performance. A clinical crit...
