This study suggests that it is not appropriate to only use the Casson equation to simulate the whole flow field of the carotid bifurcation, and on the other hand, Newtonian fluid is a good approximation to blood for flow simulations in the carotid artery bifurcation.

这表明，仅采用Casson模型模拟整个颈动脉流场是不合适的，而牛顿流体则是描述血液在颈动脉分岔血管中流动的一个很好的近似。

However, the Casson equation agrees well only when the shear rate is less than 10 s?1. The flow field of the carotid bifurcation usually covers a wide range of shear rate. We therefore believe that it may not be sufficient to describe the property of blood only using the Casson equation in the whole flow field of the carotid bifurcation.

然而Casson模型只有在低切变率条件下才与血液吻合的较好，而在颈动脉分岔血管中切变率值的分布范围却很广，因此，我们有理由认为，在整个颈动脉分岔血管流场中均采用Casson模型来模拟血液的本构关系是不够的。

Carotid arterial stiffness reflects the characteristic of the functional change of carotid artery in preclinical, and provides an earlier warning for those who tend to suffer cerebral infarction.

颈动脉僵硬度反映了临床前期颈动脉功能变化的特征，为脑梗死危险人群的预警提供了更早的信息。

Carotid body:a chemoreceptor located near the bifurcations of the carotid arteries that monitors changes in the oxygen content of the blood and helps control respiratory activity.

颈动脉体：位于颈动脉的分支点附近的化学感受器，监测血液中氧含量的变化并协助调控呼吸活动。

The arterial stiffness was increase and distensibility was decrease in isolated systolic hypertension patient in 80 or above 80 years old.we should pay attention to cure patients of isolated systolic hypertension.

≥80岁老年人单纯性收缩期高血压患者颈动脉僵硬度增加，颈动脉扩张性降低，临床上应重点关注对单纯性收缩期高血压患者的检查和治疗。

Methods The carotid artery system was dissected and the length of every segment from the crotch common carotid artery to every portion were measured with slide gaud under operating microscope in 15 Kunming mice.

在手术显微镜下，解剖小鼠颈动脉系后，用油标卡尺测定从颈总动脉分叉至各部的长度，结果以均数表示。并对尼龙单丝线末端的处理进行了较详细的研究。
