The study is to synthesize dual-site phase-transfer catalyst, and use it to form tri-liquid phases, and investigate the catalytic benzoylation of 4'-hydroxyacetophenone sodium salt and benzoyl chloride to produce 4-acetylphenyl benzoate in ultrasound-assisted tri-liquid-phase system.

中文摘要本研究在合成双活性基相间转移触媒，并使用该触媒合成三液相系统，并辅以超音波在三液相系统中催化4-乙醯基酚化钠与氯化苯甲醯形成苯甲酸4-乙醯基苯酯的反应。

"Up to 90% of patients referred for ultrasonography with suspected of the leg do not have the disease," write Harry R. Buller, MD, from University of Amsterdam, the Netherlands, and colleagues from the Amsterdam Maastricht Utrecht Study on Thromboembolism.

荷兰阿姆斯特丹大学与来自阿姆斯特丹马斯垂克乌德勒支静脉栓塞研究的同事们表示，因为腿部怀疑有深部静脉栓塞而被转介进行超音波检验的病患，其中90%并没有罹患这个疾病。

Items such as arterial filters, anesthesia filters, blood filters, IV catheters, dialysis tubes, pipettes, cardiometry reservoirs, blood/gas filters, face masks and IV spike/filters can all be made using ultrasonic welding.

项目例如动脉过滤器、麻醉过滤器、血液过滤器、IV导尿管、透析管、吸移管、人造心脏、血液或气体过滤器、面罩和IV钉或者过滤器可能所有使用超音波熔接被使用。

Methods: Between May and July 2007, 5 patients (4 female and 1 male patients) with perineal or coccygeal pain were recruited. A sacral transverse view and longitudinal view with high resolution ultrasound probe (5~12 MHz) were defined in the sacral cornua and the first cleft below the sacral hiatus was found.

使用5~12MHz高解析度超音波探头，以横切及纵切呈像先找出sacral cornua，再找出sacral hiatus后可见的第一个裂缝。

Because poor visualization of the gallbladder in abdominal sonogram, emphysematous cholecystitis is very difficult to diagnose in most of cases.

因胆囊内气体的存在，导致胆囊辨识不易，使气肿性胆囊炎较难由超音波来诊断。

He had an uneventful postoperative recovery. Elderly patients who have emphysematous cholecystitis may present with only right upper abdominal pain. Other signs may be absent. Preoperative diagnosis can be difficult. When the gallbladder is poorly visualized and gas is suspected on ultrasonography, it should be defined by plain film and computed tomography and emergent cholecystectomy is needed to minimize the risk of mortality.

急性气肿性胆囊炎的老年患者，经常只以右上腹胀痛表现而缺乏典型的症候，术前诊断不容易，当超音波检查发现胆囊无法清楚显现而怀疑胆囊内有气体存在时，必须安排腹部X光及电脑断层作更进一步确认，一旦确立诊断，必须作紧急手术治疗以降低死亡的危险性。

Endodermal sinus tumor is a rare ovarian malignancy. There is no characteristic manifestations in roentgenologic nor sonographic study.

Endodermal sinus tumor is a rare ovarian malignancy. There is no characteristic manifestations in roentgenologic nor sonographic study.

內胚层竇肿瘤为少见的卵巢恶性肿瘤，在放射线或超音波检查並没有特异的表徵。

A detailed US examination using a3.5- MHz transabdominal probe demonstrated a fused single ventricle, a fused thalami, a cleft lip and palate, and the absence of falx cerebri in her fetus.

腹部超音波显示胎儿有单一脑室，融合的视丘及缺少大脑帘并唇裂及颚裂畸形。

As seen on ultrasound, CT and MRI, pancreatic carcinoma typically presents as a focally enlarged mass in the pancreas and/or dilatation of the main pancreatic duct.

摘要在超音波，电脑断层，及磁振造影的检查，胰脏癌典型的表现是局部变大之肿块，可能伴随有胰管变粗。
