查询词典 micromotion

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。

Results Normal femoral stresses werelarger than osteoporosis ones.Interface micromotion became larger when bone mineraldensityof the femur was low.

结果 正常骨的股骨应力比疏松骨的股骨应力大，非骨水泥有肩托假体能增加股骨矩处压应力，但同时大粗隆处应力减少。

In this work,based on the principle of microdoppler,the mathematical model between missile and decoy is constructed,and characteristics in microdoppler are analyzed through simulation,thus distinguishing the target from heavy decoys and the missile.It offers a new reassuring way to the discrimination of the real or false targets.Keywords : target recognition;warhead;decoy;microdoppler;micromotion

文中在对微动目标微多普勒分析的基础上，建立了导弹与诱饵的数学模型，采用短时傅里叶变换的方法对回波信号进行微多普勒特征提取，仿真分析了导弹与诱饵的微多普勒特征，通过研究其时频分布特点的差异成功的识别出了真假目标，从而为弹道导弹与重诱饵的识别提供了一个新的有效方法。

Taking precise microminiature mechanical systems as assembly objects, the reconfigurable 12 degree of freedom microassembly technology and realization method are systematically proposed, including modules such as 6-DOF macro-robot, 6-DOF precise micromotion worktable, micro gripper integrated micro detection and feedback, and micro pose detection device, and so on.

以精密微小型机械系统为装配对象，提出了可重构12自由度微装配技术和实现方法，具体包括6自由度宏动机器人、6自由度精密微动工作台、集成微力检测与反馈的组合式微夹持器和位姿检测装置等可重构模块。

Aseptic loosening of prosthesis has become the main reason for failure. From the prospect of prosthesis design,increasing the prosthesis and bone adaptation to reduce the initial micromotion and increase long term bone ingrowth is the only way to achieve long term fixation.

而这一密合程度由髓腔形态与假体外形共同决定，因此股骨髓腔形态必须纳入假体设计的考量的中，而研究各种影响髓腔形态的因素就极具价值和意义。

In addition, this effect was superficial that made the ion-implanted surface smooth and increased its nanohardness, whereas the abrasion resistance of the treated surface to micromotion test was unobvious.

其效应使得处理后试片表面变平整，奈米硬度上升，但在耐磨损磨之耗微振磨耗测试方面，因处理试片深度为极表面，故观测不出显著之变化。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.

也许他们将在壶穴里消失
