动脉下的

The study of mechanical properties of aorta was important both in analysis of physiological and pathophysiological changes.

动脉力学性质的研究对于动脉正常生理特性的分析和病理状态下性状改变的研究有着重要意义。

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。

Four episodes of massive bleeding occurred before a definite diagnosis could be established by angiography. A high index of suspicion is the most important diagnostic aid that can prevent the physicians from overlooking the possibility that lower GI hemorrhage may have such an unusual source.

病人在经历四次动脉血管摄影后出血才得到确切控制，唯有临床高度怀疑且快速准确的动脉血管摄影检查，才可避免轻忽此一罕见下消化道出血原因，并得到立即有效的治疗。

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。

Methods:The origin, external diameter, branch and distribution of subscapular artery was observed and measured on 34 adult limb specimens.Results:The external diameter of the subscapular artery was 3.9 ± 0.3mm.

方法在34例经动脉灌注红色乳胶成人尸体上，对肩胛下动脉的起始、分支及在背阔肌外缘深部表面的分布进行解剖学观察。

Methods In 18 adult upper extremity cadavers,origins,courses, branches,distribution and the anastomosis of the medial antebrachial cutaneous nerve,basilic vein and their nutrient vessels were studied under the operating microscope.5 fresh adult cadavers,photographic developer were injected in the artery.

方法上肢标本18侧，显微剥离表皮组织，观察前臂内侧皮神经、贵要静脉及各自营养血管的起始、走行、分支、分布及与其它血管的吻合情况；新鲜整尸标本5具，动脉灌注显影剂，剥离体被组织于X光下摄影，分析皮动脉的分布及其与毗邻血管的关系。

These arise anterolaterally from the aorta almost immediately as it exits the aortic hiatus and extend over and supply the inferior surface of the diaphragm.

，主动脉几乎是一从主动脉裂孔出来，这两条动脉就从它的前外侧分支，向上行，为横隔膜下表面提供血液，它们还分别分支为多条身体同一侧的肾上腺上支动脉。

Results:According to different part of the vessels,there were 2 types:type 1,from the superficial surface of anterior belly of digastric muscle to the surface of inferior margin of mandible to subcutaneous part,accounting for 36%;type 2,from the deep surface of anterior belly of digastric muscle to the deep surface of inferior margin of mandible to s...

结果 ：根据血管走行差异分：1型：主干经二腹肌前腹浅面到下颌骨下缘表面至皮下占 3 6%，2型：主干经二腹肌前腹深面到下颌骨下缘深面至皮下占 64%；1型血管位置表浅，易于分离，且蒂较长，旋转度大，2型相比反之。结论：根据颏下动脉走行设计不同皮瓣的大小来修复面部皮肤组织

Results: The thickness of intertransverse ligament was about 0.60~1.39mm.

结果：横突间韧带厚度0.60~1.39mm；L(下标 3-5)节段动脉前支及伴行静脉90%以上位于相邻横突间韧带腹侧上1/2处，横突间韧带背侧中1/3处有一恒定节段动脉分支；腰神经前支与矢状面夹角18.90°~39.20°，下位横突的副突处距前方走行腰神经前支距离为5.63~8.05mm，椎弓峡部侧缘至腰神经前支的距离为1.73~3.64mm。

Methods (1) Through microsurgical direct destruction of the arterial intima and internal elastic lamina at the bifurcation of the carotid artery in 30 rats,saccular aneurysms can be induced immediately, and the contralateral carotid arterys were ligated in half of t...

(1)通过显微手术方法直接破坏大鼠颈动脉分叉部位的内膜和内弹力层，建立大鼠实验性囊性动脉瘤模型，并在结扎及未结扎对侧颈总动脉的情况下，观察4-5个月。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。
