微动

Whiteside and Easley demonstrated that distal fit is equally important in controlling micromotion.

Whiteside和Easley证明，远端匹配在控制微动方面同样重要。

Mechanical loosening of orthopaedic implants can be predicted by measuring the progressive micromotion of the implant with respect to the bone in the first two years after surgery.

在手术后前两年里，骨科植入物相对于骨组织的累积微动情况是可以测量的，测量结果可以预测植入物的机械松动。

Relative stability fixation allows controlled micromotion in the fracture zone but prevents fixation failure during rehabilitation until the fracture heals.

相对稳定固定允许在骨折区域的控制性微动，并且能够在骨折愈合之前的康复治疗期间固定不失败。

The most accurate Roentgen technique for threedimensional assessment of micromotion is Roentgen Stereophotogrammetric Analysis.

用于三维微动测量的最精确的X线成像方法是X线立体摄影测量分析法。

MAIN OUTCOME MEASURES: Standing on single or double feet was simulated to measure stress distribution, interface stress, and primary micromotion of femoral prosthesis in the three types.

主要观察指标：分别模拟单足和双足站立状态，测量3种股骨假体的应力分布、界面应力和初始微动情况。

The deforming forces are distributed over the large surface area of the fracture complex and these forces can be efficiently controlled to a desirable level of micromotion with bridge plating.

变形力分配到复杂骨折的大表面区域，桥接钢板能够有效控制这些力量，使之在可以接受的微动范围。

Joint friction and micromotion should inevitably form the biofilm and debris around the prosthesis, which will provide a breeding ground for the propagation of pathogenic microorganisms. On the contrary, the destruction of bone around the joint caused by infection is one of the reasons of joint sinking.

在一定条件下，术后关节感染与假体松动又是相互促进的，关节的摩擦和微动，必然会在假体周围形成界膜和微粒，这就为病原微生物的繁殖提供了条件；反之，关节周围的感染所造成的骨破坏，也是关节松动下沉的一个原因。

In addition, micromotion between the nonarticulating side of the liner and the interior of the shell may be a source of polyethylene debris generation, or "backside wear." Recognition of this problem has led to improements in the fixation of the liner within the metal shell, and some designs also hae included polishing the interior of the shell.

另外，内衬的非关节面与金属帽内面之间的微动也可能是聚乙烯颗粒产生的一个原因，这称为"背侧磨损"，认识到这个问题，人们开始改进聚乙烯内衬与金属帽间的固定，而有些类型的假体金属帽内面是抛光的。

Under cyclic pressure or torsion load, Four factors with two levels that might influence component stability were assembled into eight performing conditions by orthogonal design. Axial compression micromotion and torsion micromotion were cellected under the eight working conditions.

根据临床上多见的可能对假体微动产生影响的四种因素分设两个水平，采用正交设计方案，组合成8种处理工况对三翼臼进行轴向循环压力载荷测试，同理进行三翼臼的循环扭矩载荷测试。

Finally, according to market conditions and market products this article paper analyzes the trends in the development of camera technology, and designs a color night vision camera.

最后根据市场情况和市面上产品的情况分析了摄像机技术的发展趋势，并设计了一款彩色夜视摄像机。

Only person height weeds and the fierce looks stone idles were there.

只有半人深的荒草和龇牙咧嘴的神像。
