In fact the destruction of baby girls is a product of three forces: the ancien t preference for sons; a modern desire for smaller families; and ultrasound sc anning and other technologies that identify the sex of a fetus.

事实上，消灭女婴是三股力量共同作用的结果：自古以来就有的对男孩的偏爱，现代人对小家庭生活的追求，以及超音波检查和其它能够确定胎儿性别的技术。

The efficacy assessment was performed by cycloplegic refraction and axial length measurement.

以睫状肌麻痹后验光与超音波测量的方式分别检验近视度数的增加及眼轴增长的情形作为三组比较的基础。

Fluorescent penetrant inspection makes use of a highly fluorescent liquid with unusual penetrating qualities.

半新的频率在人的耳朵，因此名字听见的那些之上是远的超音波。

The experimental results on the clinical ultrasound images and phantom images show that not only have the most perceptible objects of interest been identified, but also the septa of object have been preserved.

在临床超音波影像与假体实验的结果中，我们不仅能够找出最明显的目标物，目标物内部的中隔边界也可以完整的保留下来。

In 84 preterm infants with ultrasound abnormalities, the investigators serially videotaped and blindly observed general movements from birth until 56 to 60 weeks' postmenstrual age.

从84名经超音波诊断为瘫痪的患儿中，研究者连续记录和摸索观察，从出生到胎龄为56到60周的婴儿的全身性运动。

MATERIALS AND METHODS: From September 1997 to September 1999, 56 patients with either infertility (36) or scrotal discomfort (20) who underwent subinguinal microsurgical varicocelectomy were reviewed. All patients were confirmed as having varicocele by pre-operative color flow mapping.

材料与方法：从1997年9月到1999年9月，回顾了五十六个或者不孕（36）或者阴囊不适（20）的患者，接受鼠蹊管下方的显微精索静脉切除手术，所有病人都采用术前彩色血流杜卜勒超音波确定诊断为精索静脉曲张；此外，以Wilcoxon等级测验统计应用於精虫变化的比较。

These data show that HRUS may assist in the management of gout in two ways: first, by aiding in the diagnosis by identifying the sonographic features that may be representative of the disease, and, second, by allowing the early detection of erosive joint damage and/or tophaceous deposits even in clinically silent joints.

这些数据表明HRUS可能在两方面协助痛风的治疗：第一，通过确定可能代表疾病的超音波特征协助诊断，第二，允许糜烂关节损害和/或痛风石沉积物的早期检测，即使在临床沉默的关节上也是如此。

Also, if your opponent is outplaying you while you are on the offensive, keep on the lookout for Sonic Emitters that may pop up.

同样，如果你对手的技术比你强，在你进攻的时候，要密切注意可能突然出现的音波塔。

This paper explored successfully the qualitative and quantitative analysis of flow field in pipeline imposed on ultrasonic flowmeter. With the installation of the flow conditioner, the non-symmetry flow and swirl flow of disturbant factors were effectively reduced.

本论文成功的探讨管流场对超音波流量计定性与定量的影响，流场因为90度弯头、T型管、…等影响流场稳定的因素存在，若不装整流器，所产生流场的不对称性及涡漩，将会持续到43.5D以上。

There are two different TPAs (2mm and 4mm) to wear and the wearing time is 7 days for each one. The volunteers were examined by the B+M mode ultrasonography for the subjective tongue movement during swallowing and by the visual analogue scales for the objective self-evaluation (dysphagia, toothache, pain of tongue).

选取15名健康的成年志愿者为受测对象，使用防震扫描技术之B模式结合M模式口腔超音波做舌头之吞咽运动的纪录与客观测量数据，和使用视觉类比尺度做受测者的主观自我评分纪录（吞咽困难度、牙齿疼痛度和舌头疼痛度）。

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。
