Methods Transvaginal color doppler sonographywas performed in 42 cases with hysteromyoma and35 cases with adenomyoma to analyze the characteristics of transvaginal two dimensional and color doppler flow with them,and to measurate the resistance index of uterine artery and the RI of focus.50 normal women were chosen for control.

对35例子宫腺肌瘤、42例子宫肌瘤患者行经阴道彩色多普勒超声，分析其二维及彩色多普勒血流特征，并测定各组子宫动脉、病灶周边及内部RI。

The hemodynamic effects of intravenous injection of agmatine and their cellular mechanism were investigated in anesthetized rats.

在麻醉大鼠研究静注胍基丁胺对血流动力学的影响，并初步探讨其机制。

CT perfusion images can visually show different traits of Hemodynamics of hepatic Benign and Malign pathology; No matter what background, various parameters of hepatic tissue around malign lesions had significant difference with far-end liver tissue, while various parameters of hepatic tissue around benign lesions had no significant difference with far-end liver tissue; Allopatric efficiency of hepatic Malign pathology distinctly went up with hepatocirrhosis background;Various parameters of hepatic Benign and Malign pathology had no significant difference and differential significance were no significant.

灌注参数图像能直观显示肝脏良、恶性占位性病变血流动力学的不同特点；无论在何种背景下，恶性病变灶周组织与远端肝组织各同种参数间有显著差异，而良性病变灶周组织与远端肝组织各同种参数间无显著差异，以上特点可以鉴别肝脏占位性病变的良、恶性；肝硬化背景下，恶性病变的发生率明显增高；正常肝组织背景下，良、恶性占位病变组织灌注参数间无显著差异，鉴别诊断意义不大。

Stenoses, and ealuation of carotid disease in patients with arrhythmias, alular heart disease, or cardiomyopathy.

由于CTA依靠造影剂灌注识别狭窄的血管腔病变，很少由于血流紊流和动脉扭曲而过高估计血管狭窄。

The size,shape,number,interior and ambitus bloodstream of lymph nodes were observed and re examination was done 7,14 days after anti- inflammatory treatment.

形态及其内部及周边的血流情况，并于抗炎治疗7天和14天后复查。

Lots of clinical studies show that early opening of occlusive coronary artery can help resume the forward flow of coronary artery, protect amort cardiac muscle, reduce infarction area, improve heart function and reduce mortality.

大规模临床研究表明，尽早使闭塞的冠状动脉开通，恢复冠状动脉前向血流，可保护濒死心肌，缩小梗死面积，改善心功能。

OBJECTIVE:To study the anatomic structures and the blood flow parameters of normal fetal cerebral artery.

目的：研究正常胎儿颅内动脉的结构和血流动力学参数。

These depositsdecrease blood flow to the heart and may promote the formationof vessel-blocking clots, which can result in anginal chestpain or even a life-threatening heart attack.

这些储蓄减少血流对心脏，也许促进船阻拦的凝块的形成，可能导致anginal 胸口痛甚至一次威胁生命的心脏病发作。

Numerically evaluate the value of the largest Lyapunov exponent on diagnosing the various stenosis degrees of internal carotid arteries in white rabbits and in order to diagnose the angiostenosis with transcranial Doppler ultrasound.

探讨了血流信号的最大Lyapunov指数在诊断白兔颈内动脉不同程度狭窄中的价值，以期达到利用经颅多普勒超声量化诊断血管狭窄的目的。

Such neural code transmission readjusts the angiotasis and regional blood perfusion.

这种神经信号的传递，对血管张力以及改变局部血流灌注起到调节作用。

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。
