摘　　要：本文重点介绍用于心血管内流场的高质量模拟的动态流体双折射实验技术和系统。首先制备了两种仿血双折射液和一种弹性透明的硅橡胶模拟血管，有关参数测定表明它们适用于模拟血流和血管。其次，为了消除光线穿过圆管产生的图象畸变，用光线追迹法推导出消畸方程并选用最佳匹配浸渍液消畸。最终设计建立了一台由微机控制的集流动、光学、图象与数据采集处理和同步控制子系统于一体的新型测量系统。In this paper,practical technique for simulating blood flow are emphasized.According to the mechanical properties of large blood vessel and the blood,two kinds ofbirefringent solutions for Simulating blood flow and one kind of silicon rubber for simulatingblood vessel were found and measured.In order to eliminated the isochromatic pattern distortiondue to multi-refraction Of ray through a cylindrical model,refraction equations were derivedand the optimum immersion liquid to eliminate the isochromatic pattern diStortion was used and annew experimental system was designed.
