超声的

The purpose of the present investigation is to evaluate the distensibility of both ascending and descending aorta in different type of aortic dissection by comprehensive transthoracic echocardiography and transesophageal echocardiography.

本研究在上一研究的基础上，联合应用常规经胸超声和经食管超声，对不同类型主动脉夹层(DeBakeyⅠ型夹层12例及Ⅲ型夹层11例)之不同部位主动脉扩张性进行更进一步深入对比研究，试图揭示主动脉夹层血管弹性异常的根本原因。

Objective To explore sonogram of transvaginal colour dopper sonography in ectopic pregnancy conservative treatment and to improve monitor effectivity.

Color Dopper sound is charactered with convience and high coincidence of diagnosis,CDPI can conclude if there is residual of tiny embryo to those women accompanied with colporrhagia whose finding of 2 D ultrasound is normal.

彩色多谱勒超声对不全流产具有检查方便快捷及诊断符合率高的特点，尤其是对仅表现为阴道出血，二维超声无明显表现的患者，CDPI可判定有无微小胎物残留。

METHODS Left ventricular ejective fraction, regurgitant velocity and regurgitant direction were examined by color Doppler echocardiography in 151 patients with medium mitral regurgitation. The results of LVEF, regurgitant velocity and regurgitanting gradient were compared between patients with and without murmur grope.

随机选择151例经超声心动图检查，显示有中度及中度以上二尖瓣返流的患者，根据彩色多普勒血流显像分别测定LVEF、返流速度等超声参数，比较其在杂音组及无杂音组间统计学差异，分析其对听诊的可能影响。

In particular it optimizes the parameters of the extension spring that is a crucial part in such a flexible infinitely variable-diameter system.

特别是对超声检测柔性无级变径系统的重要部件拉伸弹簧进行了参数优化，对超声变径检测装置的设计具有重要指导意义。

In our experience, the performance of this system is excellent if you do a complete ultrasound examination of the patient and you select the area of the intercostal space with ultrasound before you do the exam.

在我们的经验里，如果对患者进行全面超声检查，用超声选定肋间隙的一块区域，然后用这个系统检查，则其性能极佳。

Using both screens together found 34 out of 38 cases of ovarian cancer that eventually developed, while ultrasounds alone found 24 out of 32, Jacobs and Menon reported.

Jacobs 和 Menon报道，联合超声和CA125发现了38例卵巢癌中的34例，而单用超声发现了32例中的24例。

Objective: To explore the application value and the guidance for surgical operation of transthoracic echocardiography and multiplane transesophageal echocardiography in the diagnosis of Ebstein's anomaly.

目的：探讨经胸超声心动图和多平面经食管超声心动图在三尖瓣下移畸形诊断中的应用价值及对外科手术的指导意义。

Objective To investigate the diagnostic value of transvaginal color Doppler ultrasound in obstetrical and gynecological emergency.

目的总结各种妇产科急症的超声诊断情况，探讨经阴道彩色多普勒超声在妇产科急症诊断中的应用价值。

Experimental research on ultrasonic honing engineering ZrO2 ceramics was carried out with W20 and W7 oilstone . In tests we studied the influence of ultrasonic honing on surface damage ratio, as well the influence of honing technics parameters on surface roughness.

采用W20和W7珩磨油石对氧化锆工程陶瓷进行了超声珩磨试验研究，给出了超声珩磨条件下对表面破碎率的影响以及珩磨工艺参数对表面粗造度的影响。

And Pharaoh spoke to Joseph, saying, Your father and your brothers have come to you.

47：5 法老对约瑟说，你父亲和你弟兄们到你这里来了。

Additionally, the approximate flattening of surface strip using lines linking midpoints on perpendicular lines between geodesic curves and the unconditional extreme value method are discussed.

提出了用测地线方程、曲面上两点间短程线来计算膜结构曲面测地线的方法，同时，采用测地线间垂线的中点连线和用无约束极值法进行空间条状曲面近似展开的分析。
