通过折射率匹配方法，应用激光多普勒测速仪测量了突缩与分叉复合管内的液体流场。
Liquid flow field in a tube with a combination of a stenosis and a bifurcation was measured using refractive index matching technique.
分别测量导丝分叉点到病灶中心点的距离，同时对患者舒适度进行评分，并统计不良反应发生率。
The distance from bifurcation of wire to lesion center was measured, the degree of comfort and adverse reaction was reported and recorded, and then were statistically analyzed.
IVUS对离心性、钙化、左主干、分叉部位和弥漫性病变的检出率显著高于CAG（P< 0 .0 5 ）。
The rates of detection with IVUS were more than those with CAG for calcified lesion, eccentric lesion, diffuse lesion and lesions in left main trunk and bifurcation(P<0.05).
