不阻断下腔静脉的全肝血流阻断术既能控制术中出血，又能保证全身血流动力学稳定。

Pringle maneuver combined with hepatic veins occlusion for complicated hepatectomy is safe, and is effective to prevent dangerous bleeding and air embolism with less disturbance of systemic hemodynamics.

Pringle′s法联合肝静脉阻断技术在复杂肝切除术中既能达到减少术中出血的目的，又能防止术中肝静脉破裂导致空气栓塞，还避免了下腔静脉阻断所引起全身血流动力学紊乱，是一种更安全、有效的血流阻断技术。

Results: findings on 2d us included: irregular shape or spiculate margin were in 163 of 168 (97.0%) breast cancer; heterogeneous and hypoechoic echoes were in 165 of 168 cases (98.2%); micro calcification were in 86 of 168 cases (51.2%). in cdfi, blood flow was 98.8% found. 151 cases (90.9%) were found perforating blood vessels.

结果： 二维超声中，病灶形态不规则或有蟹足样突起者占97.0%，病灶内部回声低而不均匀者占98.2%，其中有微钙化者占51.2%，彩色多普勒血流显像中血流信号的检出率为98.8%，其中90.9%有穿入性血流，阻力指数≥0.70者占78.3%。

Result: The size and vessel caliber of thyroidea of the two groups pre-treatment were obviously bigger than those of the control group, the volume of blood flow and blood flow rate were obviously slower than those of the control group ( P .001), the sizes of thyroidea of the two groups became smaller, especially the group B1 was more obvious, and there was no significant difference in the size of thyroidea between group B1and control group.

结果：治疗前甲状腺大小、甲状腺上动脉管径、血流速度及血流量均明显大于正常组( P 。001)，治疗后，经典治疗组和联用夏枯草口服液治疗组甲状腺均有不同程度缩小，甲状腺上动脉管径变小、血流速度及血流量逐渐下降，但甲状腺大小以联用夏枯草口服液治疗组为明显，此组与正常对照组相比已无明显差异，甲状腺甲状腺上动脉、血流速度及血流量两组之间比较无明显差异。

MCA can be insonated through optical window. PI measured by transoptical and transtemporal investigation is consistent. However, flow velocity is slower in transoptical than in transtemporal, so the flow velocity of MCA in transoptical test needs to be cautious in clinic application.

眶窗检测MCA方法可行、检出率高，PI结果与颞窗检测一致，因此，颞窗缺如患者可经眶窗检测大脑中动脉血流速度，但要注意两窗所测血流速度的结果有差别，故临床宜慎用经眶窗测定的MCA血流速度结果。

Results Artery wall,vessel lumina and flow can be displayed by color Doppler flow imaging directly.Hemodynamics change can be displayed by spectrum Doppler.

结果 彩色多普勒血流显像可以直观地显示动脉管壁情况、管腔回声及血流充盈情况，频谱多普勒可以显示血流动力学改变。

Color Doppler flow imaging showed that the blood flow peak velocity of torsional testicle was lower and resistent index was higher than the uninjured side.

彩色多普勒血流显像显示有血流供应的扭转睾丸较健侧血流峰值速度降低，阻力指数升高。

The systolic and mean cerebral blood flow velocities, resistent index, and frequency spectral shape were determined.

结果 SAS组与对照组收缩期血流峰值，平均血流速度，阻力指数等9项指标差异均有显著性(P＜0.05～P＜0.01)，血流频谱形态异常SAS组增多，并且VS、VM与呼吸暂停指数呈显著负相关(r=-0.413～-0.628，P＜0.05～0.01)，与SaO2呈显著正相关(r=0.435～0.712，P＜0.05～0.01)。

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。
