The differential diagnosis of hepatic artery aneurysm and pancreatic pseudocyst is difficult by real-time ultrasound.

肝动脉瘤在腹部超音波检查有时会被误认为是胰脏假性囊肿。

Diffuse, tiny punctate calcified spots within the tumor were well demonstrated on CT and ultrasound, which have not been seen in most DSCTs reported before.

同时在电脑断层及超音波下可见到肿瘤内部有明显的散布性点状钙化，该项发现极少见於以前的病例报告中。

As assessed by rheometry, the rigidity of collagen gel, ranged from 10 to 120 Pascal, was elevated by age effects and lowered by sonication.

以流变仪来测定胶原蛋白凝胶的黏弹系数，其黏弹系数范围从10到120 Pascal，其系数随老鼠年龄增加而上升，随超音波震荡时间增加而减少。

Results. Central nervous system anomalies were diagnosed in six fetuses and sacrococcygeal teratoma was diagnosed in one fetus by prenatal ultrasound.

结果 总共有七个病例，其中包含六个中枢神经系统异常的病例，另有一个病例为sacrococcygeal teratoma，都由产前超音波诊断。

Ultrasonography is an effective, non-invasive and safe method to evaluate scrotal mass.

超音波对评估阴囊肿块是一种有效，非侵入性且安全的方法。

Acetone and SDS have been added to CH2CL2 solution containing PLA. After sonification of 20 minutes, this polymer solution has been dropwisely added to aqueous solution containing 8-14% Pluronic F-68 surfactant and stirring with homogenizer (25000 rpm). With rota-evaporator to remove solvent, polyester nanoparticles possessed average size between 61 and 64 nm. Other combinations of surfactants, such as : SDS and PVA, PAA and SDS, used in preparation of nanoparticles of polyester, resulted in much larger particles compared to above.

丙酮和十二烷基硫酸钠加入溶於二氯甲烷的聚乳酸中，并经超音波振荡20分钟，所产生的高分子微粒溶液再滴入以均质机搅拌(25000 rpm)含有(8-14%) Pluronic F-68界面活性剂溶液中，经减压浓缩除去溶剂后，奈米聚酯微粒平均粒径大小为61-64 nm，其他界面活性剂组合，包括十二烷基硫酸钠与PVA、PAA与SDS，其产生聚酯平均粒径皆大於此。

SCNB was restricted to patients with suspect breast lesions presented as microcalcification (15 cases), nodular density with calcification (7 cases), spiculated mass with microcalcification (2 cases), nodule (1 case) or architectural distortion (1 case) on mammograms.

所有病变皆经超音波扫描证实为非囊性。

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。

In the postnatal period these cases were managed conservatively and followed by renal echogram and Tc-99m diethylene triamine penta-acetic acid diuretic renal scan as needed. Four of these six units (66.7%) resolved spontaneously within 1 to 6 months. The other two lesions deteriorated within 6 months and surgical intervention was required.

吾人采保守性疗法，而以肾脏超音波或同位素利尿剂肾脏摄影检查来追踪这些病例；其中四个肾脏病变於六个月之内自行恢复正常，另两个肾脏病变则於六个月之内渐渐恶化，最后接受了外科的矫正治疗。

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。
