Objective To investigate the clinical value of B-flow in accessory diagnosis of vitreous hemorrhage.

目的 评价二维超声血流显像技术辅助诊断玻璃体出血的临床应用价值。

After application of an external pressure wae, usually at the mouth, the subsequent pressure-flow relationship can be analyzed in terms of respiratory impedance.

在外部压力波的应用后，通常在嘴里，后来的压力-血流关系能以呼吸阻抗的方式分析。

Results Three different flow wave pattern were observed,consisting of quadriphasic pattern,triphasic pattern and biphasic pattern.

结果 窦性心律左心耳血流频谱的波相可分为4相、3相、2相三类。

Nick is propped up in the woodshed, a pool of blood on the ground.

在柴房里，Nick坐在地上，血流了一地。

Anaesthesia with TCI remifentanil and fentanyl not only can provide perfect acesodyne、maintain steady circulation but also can have a faster recovery from general anaesthesia with better quality than other two methods.

但瑞芬太尼联合芬太尼既能提供完善的镇痛，维持术中血流动力学平稳，术毕又能苏醒迅速且苏醒质量高。

Cases were the diseases with two or super-two kings of abnormity, including 25 cases' chronic obstructive pulmonary disease, 7 cases' pulmonary alveolar proteinosis and 5 cases' viral pneumonia. The DGGO had presented mosaic-fashion's shadow or geographic change or crazing paving pattern, or the DGGO had centrally distributed with lobular central node, acinose node and interstitial fibrosis. Conclusion DGGO may be seen in various diseases.

两种因素或两种以上因素异常的疾病有慢性阻塞性肺病25例、肺泡蛋白沉积症7例及病毒性肺炎5例，慢性阻塞性肺病为通气-血流障碍所致，其磨玻璃影与低密度区形成马赛克样改变，常伴有桶状胸；而肺泡蛋白沉积症及病毒性肺炎同时具有气腔和固有肺结构异常，其磨玻璃影是间质性病变与实质性病变共同作用的结果。

Uncomfortable symptoms including dizziness, dim eyesight, cardiopalmus, acratia will appear when seated for a long time because of cerebral blood flow reduced for the reason of cervical vessels flexure or compressed, which result in lack of oxygen and nutritive materials.

由于久坐头处于前屈位，颈部血管轻度屈曲或受压，会使流向脑部的血流受到限制，脑血流量减少，从而造成大脑的氧和营养物质供应不足，出现头晕、眼花、心悸、乏力、手足麻木等不适症状。

Methods To measure the thickness and blood supply volume of musculus pectoral major of both sides on 20 patients after reduced radical operation of breast cancer by colour Doppler blood stream imaging. Muscle strength of musculus pectoral major and upper extremities adducent angle were measured at the same time.

采用彩色多普勒血流显像仪对20例行乳腺癌简化根治切除术(patey dyson手术)术后病人的双侧胸大肌厚度、血液供应量进行测量，同时测量双侧胸大肌肌力及上肢内收角度。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
