Solvent extraction of gold from alkaline aurocyanide solutions has more potential advantages over present zinc-dust cementation and carbon-adsorption procedures.

溶剂萃取法从碱性氰化液中提取金的工艺相对于传统锌置换法和活性炭吸附法具有潜在的优势，因而备受青睐。

The reconstruction methods for acetabular rotation center included standard THA, structural autografting and medialization of acetabular rotation centers.

髋臼旋转中心的重建方法包括标准的全髋关节置换术、结构性自体植骨和髋臼旋转中心内移。

Beings and occurrences displaced bytime and space, and long lost to the history of Man were pulled s creaminginto the ever-expanding domain.

存在与事件被置换时空，并在人类历史上被遗忘已久的历史中，再次惊叫着被拖向那不断扩张的黑暗领域。

Strict attention to detail in the surgical technique of implantation of the femoral component remains identical to that of cementless primary THA.

严格注意于在股骨假体植入的手术技术中的细节，同非骨水泥型初次全髋置换仍然一样。

Engh et al. made detailed examinations of stress shielding of the femur after cementless total hip replacement.

Engh等对无骨水泥固定全髋关节置换后股骨的应力遮挡作了详细的检测。

Objective: To analyze the change of periprosthetic bone mineral density after cementless total hip arthroplasty by dual-energy X-ray absorptiometry.

方 法］对41例全髋关节置换术后患者股骨及髋臼假体周围BMD进行12个月的动态观察，并与23例术后5年以上的患者比较。

Objective To investigate the role of aprotinin blood anesthesia used in the joint replacement and the effect on the blood coagulable function.

目的探讨抑肽酶血液麻醉在关节置换外科手术中的使用价值及对凝血功能的影响。

Aprotinin blood anesthesia can reduce the volume of hemorrhage and transfusion and not influence the coagulable function. It is worth using in the joint replacement operation.

结论抑肽酶血液麻醉可明显减少关节置换外科手术的出血量，减少异体血的输入，且不影响凝血功能，值得推广应用。

In this study, novel nanostructures of metal gold were discovered, including sheet, flower, wire and coralloid shapes. We demonstrated the synthesis of gold nanostructures via Galvanic displacement reaction.

本论文的研究乃在於利用简易的贾凡尼置换反应，於溶液中添加十六烷基三甲基氯化铵(cetyltrimethylammonium chloride； CTAC)以合成片状、花状与线状奈米金。

It is expected that hyg would be integrated stablely into the chromosome along with insert while spc/str would be lost during the second cross-over. Gene replacement through these two flanking sequences will result in the susceptibility of the transformants to phage φHAU3, which provides an enrichment for desired transformants by counterselection.

预期在携带有大插入片段的基因置换YAC分子进入野生型变铅青链霉菌后，YAC分子将通过1.4kb或1.0kb片段与染色体发生同源单交换，继而发生同源双交换，hyg连同大插入片段一起稳定地整合到染色体上，而spc／str丢失，从而导致菌株Hyg〓Str〓的表型。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
