摘　　要：用动态流体双折射法对三种有代表性的心血管模型（模拟大血管、动脉狭窄和人造心脏瓣膜）中的脉动血流间隙测试，得出速度剖面，剪应力分布，压力和流量之间的相位关系。结果说明本文所描述的双折射液和模拟血管是适用于心血管内流场的高质量模拟实验的，动态流体双折射方法及简化的光－力学关系是适用于低频脉动模拟血流的定量分析的。In the present research work, pulsatile flow patterns of three typical models forSimulating large vessele, arterisl stenosis and artifical heart value, respectively, were visualized andanalysed. Volecity profieles,shear stress as well as the phase relation between the flow rate and thepressure were discussed. Especially,the flow rate waveform obtained from the dynamic birefrinsenceanalysis is in good agreement with the measured result. This indicated that the dynamic birefringencetechnique and simplified relation presented in this paper can be used to obtained quataties for the lowpulsatile flow.
