Were used to detect the experimental group and control group, supine position when the left renal vein compression section diameter of the expansion of paragraph a, b, left renal vein peak velocity pressure above Va, the pressure gradient, pressure, as well as the expansion of left renal vein peak velocity Vb paragraph and to observe the two forms of the spectrum, and then testing all the main subjects with renal renal artery, interlobar artery and renal blood flow velocity of the main renal artery resistance index; record of the experimental group urine test subjects in the number of red blood cells.

分别检测实验组及对照组平卧位时左肾静脉受压段、扩张段内径a、b，左肾静脉受压段峰值血流速度Va、压力阶差、压力，以及左肾静脉扩张段峰值血流速度Vb并观察两处的频谱形态，再检测所有受检者双肾主肾动脉、叶间动脉的血流速度及双肾主肾动脉阻力指数；记录实验组受检者尿常规化验中红细胞数量。

Objective:To study intramyocardial flow characteristics in patients with coronary artery disease by color Doppler coronary flow imagingand to assess clinical value of CDCFI.

目的：应用冠脉血流显像技术评价冠心病患者的心肌内血流特征，探讨该技术在检测心肌内血流方面的价值。

Vascular endotheliocyte fluorescence staining and leukocyte fluorescence tracing method were applied, in combination with microscopic video system and computer imaging analyzing system, to observe in dynamic and quantitatively the influences of acupuncture on pia matral encephali microvascular morphology, density and blood flowing velocity at 3 hours, 6 hours and 24 hours after cerebral occlusion of meddle cerebral artery.morphology, density and blood flowing state at various time divisions observed directly microscopically and vascular endotheliocyte morphology and the state of brain tissue which near the microvascular after infusion with velocity in infarcted area at various time divisions measured in quantity in each group.microvascular endotheliocytes were colored worse and more fluorescent exudation appeared.

采用血管内皮细胞荧光染色及白细胞荧光示踪法，结合显微录像系统和计算机图像分析系统，动态定量地观察了针刺对大脑中动脉阻塞后3，6，24h软脑膜微血管形态、密度、血流速度的影响。主要观察指标：①从显微镜下直接观察各组大鼠不同时段软脑膜微血管的形态、密度、血流状况，以及注入荧光剂后血管内皮细胞形态和周围脑组织状况。②定量测量各组大鼠不同时段梗死区微血管密度、血流速度。结果：120只大鼠均进入结果分析。

Results Oviducal pregnancy were typed as unruptured pregnant vesica, tubular low echo abortion and ruptured mixed mass.

结果输卵管妊娠可表现为未破裂孕囊型、管状低回声流产型和破裂混合团块型，附件区可探及阻力指数0.44 0.11的动脉血流频谱；未破裂孕囊型、管状低回声流产型和破裂混合团块型的附件区团块内部及周边血流丰富程度呈递减趋势，同时血流信号的丰富程度与血β—HCG测定值呈正相关，阻力指数与血β—HCG测定值呈负相关。

Results There were slight and remarkable pulsatility in portal vein flow respecti...

结果 正常人门静脉血流频谱随呼吸周期有轻度的波动；三尖瓣返流者门静脉血流的呼吸性变化较正常人显著，且随返流程度的增加而增大，直至出现逆向血流。

On the days of 3, 9, 21 and 30 postoperatively, mean blood velocity, pulsatility index and resistance index of anastomosed arteries were determined by Ultrasonography Doppler.

三组分别于术后 3、9、2 1及 30天，采用彩色多普勒超声诊断仪检测吻合口部平均血流速度、血管搏动指数及血流阻力指数三项血流动力学指标。

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。
