置换的

In most instances, a trade-in is viewed as both a sale of the old asset and purchase of a new one.

在大多数情况下，置换被看作是旧资产的售出和新资产的同时购入。

Methods The tricuspid valve function was evaluated by Doppler echocardiography in 903 patients who underwent mitral valve replacement during recent 10 years.

对接受二尖瓣置换术的903例病人术后三尖瓣功能进行了2～9年，平均（3.6 2.4）年的跟踪观察。

Background: We reviewed the patients who underwent tricuspid valve replacement to compare the long-term clinical results of bioprosthetic valve with mechanical valve in tricuspid position.

背景： 对接受过三尖瓣置换术的患者进行回顾，比较生物瓣膜和机械瓣膜的远期临床效果。

Background: We reviewed the patients who un der went tricuspid valve replacement to compare the long-term clinical results of bioprosthetic valve with mechanical valve in tricuspid position.

背景：对接受过三尖瓣置换术的患者进行回顾，比较生物瓣膜和机械瓣膜的远期临床效果。

The vertical distance from tibial tubercle top to the joint line is 22.3 mm.

我们建议医师在首次置换手术时，参考我们的结果以正确的放置股骨元件。

This paper is mainly made up of two parts. One is to apply Computational Fluid Dynamics in turbulent flow of displacement ventilation room.

本论文主要由两部分组成，一部分是应用计算流体力学的理论与方法模拟置换通风房间空气的流动情况并进行分析。

Making use of the Kleinberg's small world theory, the method breaks the RPV table into two tables: the local short chain RPV and the long chain RPV. The RPV guarantees the acquirability and reliability of discovery and the RPV which is constructed by probability replacement of long chain strategy can speed up search.

该方案利用Kleinberg的小世界理论，将RPV表分解为本地短链RPV表和长链RPV表，本地短链RPV表可以保证搜索的获得性和可靠性，长链RPV表可以实现快速搜索，同时采用概率置换长链策略构造长链RPV表。

The current diˉagnosis of diabetes in elderly use the American Diabetes Association criteria for diagnosis of diabetes,and use insulin or oral diabetes to medicines control hyperglycemia,Internal fixation of intertrochanteric fracture of femur is performed by dynamic hip screwor"γ"screw.

目的 探讨老年人糖尿病与髋部骨折发生的关系方法回顾分析1999年2月～2003年4月收治的女性髋部骨折患者338例，年龄65～85岁，平均（74.3±4.3）岁，采用美国糖尿病协会标准诊断糖尿病，口服降糖药或胰岛素注射控制血糖，DHS、&γ&钉内固定粗隆间骨折，人工髋关节置换术治疗股骨颈骨折。

The rotating disc of Cu has been used to study the kinetics of Ag cementation on metallic Cu in ammoniacal solution. Two stages of reaction rate were found in this cementation process, i.e., an initial slow rate and a second enhanced rate.

用Cu的旋转圆盘研究了氨性溶液中Cu置换Ag的动力学，观察到有两段反应速率，即初始段反应速率慢和第二段反应速率增快。

Sikorski and Barrington36 followed for 2 years 7 patients who had undergone either an anterolateral or a posterior approach

一项对Cochrane数据库的回顾只找出一项在114例病人中比较半髋置换手术入路的随机对照试验。

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％。
