查询词典 carotid

In the present study, three different blood constitutive models, namely, the Newtonian, the Casson and the hybrid fluid constitutive models were used in the flow simulation of the human carotid bifurcation. The results were compared among the three models.

为此，本文采用数值方法比较了三种不同血液本构关系（牛顿模型，Casson模型和混合模型）所模拟的血液在颈动脉分岔血管内的流动情况。

Finally, receiver operating characteristic curves of the four index of blood lipid were used to predict the presence of carotid plaque.

最后对血脂四项指标绘制ROC曲线评价其对颈动脉斑块的预测价值。

PO_2; PCO_2; pH ; carotid chemoreceptor ; afferent unit discharge

氧分压；二氧化碳分压；酸度；颈动脉体化学感受器；传入单位放电

In addition, excessive collarband oppression of the neck carotid sinus in pressure sensors, neural reflex, causing blood pressure and heart slows down, the brain occurs vbi, headache and dizziness, nausea, eye emit a beautiful wait for a phenomenon, especially with hypertension, atherosclerosis, coronary heart disease, diabetes, very easy occurrence faints and shock.

另外，过紧的领口压迫了颈部的颈动脉窦中压力感受器，通过神经反射，引起血压下降和心跳减慢，使脑部发生供血不足，出现头痛、头晕、恶心、眼冒金花等现象，尤其是患有高血压、动脉硬化、冠心病、糖尿病的人，很容易发生晕倒和休克。

Objective To prevent arteriosclerosis and treat hypertension,we studied the relationship between carotid complaisance and hypertension in patients aged 80 and above.

目的 研究≥80岁老年人高血压与颈动脉顺应性的关系，为治疗高血压和预防动脉硬化提供依据。

It also gives opportunities to the patients with contraindication to carotid artery endarterectomy.

实验证实，其对卒中二级预防的效果与经典的颈动脉内膜切除术相同。

Methods the multi-infarction dementia model was induced by injecting cruor embolus of the same kind rats into the internal carotid artery.

采用同种大鼠自然干燥血凝块颈内动脉注入制备多发性脑梗死性痴呆大鼠模型，测定多发性脑梗死大鼠血清s

Methods The multi-infarction dementia model was induced by injecting cruor embolus of the same kind rats into the internal carotid artery. The SOD and MDA of serum was measured. And the pathology of brain was observed.

采用同种大鼠自然干燥血凝块颈内动脉注入制备多发脑梗死痴呆大鼠模型，测定多发脑梗死大鼠血清SOD、MDA的含量，观察脑组织形态学改变。

Objective To study the power spectrum density of blood flow ultrasonic Doppler signal using wavelet analysis. Method Doppler signal of blood flow in human common carotid artery was studied with wavelet scalogram analysis, an affine smoothing Wigner Ville transform with a constant "Q" character. Result Wavelet scalogram of blood flow ultrasonic signal had a higher distinguishability than STFT spectrogram in the low frequency portion, but had poorer decussation terms than spectrogram.

对于平稳信号的处理工具仍然是Fourier变换，但是，在实际应用中的绝大多数信号是非平稳的，现在看来处理非平稳信号的主要工具将是小波变换，这主要是因为传统的Fourier变换分析信号时，时间和频率分辨率精度是固定不变的，而利用小波变换分析信号，在信号高频段时间分辨率精度也较高，在信号低频段频率分辨率精度较高，这很符合非平稳信号的特点。

When we used a broader defi nition of CVD that also included coronary or carotid revascularisation, the ages were 41·3 and 47·7 years for men and women with diabetes respectively.

当我们观察广义的CVD（也包括冠脉和颈动脉的血管成形术）时，男性和女性糖尿病患者进入高危组的年龄分别是41.3岁和47.7岁。

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
