旋转关节

Pseudoparalysis of the shoulder and severe rotator cuff arthropathy are contraindications to this procedure.

肩关节假性瘫痪和严重的旋转撕裂是这个方法的禁忌症。

The results were as follows.(1) In the backward handspring, the trajectory of CM and horizontal velocity of CM in junior-high and college gymnasts were lower and higher than those of senior-high gymnast, so the vertical velocity is better when they perform tucked backward somersault. College gymnast has higher vertical velocity than junior-high and senior-high gymnasts in take-off moment of backward handspring phase.(2) Senior-high and college gymnasts have more elbow and shoulder angle in take-off moment of backward handspring and tucked backward somersault phase. Therefore, angle of both arm is bigger for performing in hand push away phase in the backward handspring, and increased the reaction force with body in the tucked backward handspring.(3) College gymnast has large knee flexions in hand support and push away moment in the backward handspring, it would increase rotation radius and better moments of inertia in the backward handspring.

结果显示：在后手翻阶段中，较低的重心轨迹和较高的水平速，有於后续空翻的垂直速；大专选手在后手翻阶段起跳瞬间有较高的垂直速；高中及大专选手在后手翻起跳脚地瞬间和团身后空翻起跳脚地瞬间时，肘、肩关节角皆大於国中选手，使其在后手翻起跳地瞬间时，双臂的伸展於后手翻的手推地面的动作，而团身后空翻起跳脚地时，双臂向上摆於身体向上伸展方向的掌握，并使重心有一定的腾空高；大专选手在后手翻阶段的手著地瞬间和手地瞬间的膝关节角较大於高中和国中选手，使其可增加身体的旋转半径，并能获得较佳的下摆动能，而膝关节角小则形成屈膝的动作，导致重心水平速低，减少下摆动能和影响整体动作的节奏和韵。

Rotating hinge prostheses are strongly recommended for use in Charcot joint.

大部分病例的Charcot关节移植可旋转铰链式假体是令人满意的。

An inside conical surface at the lower end of the joint is designed to ensure the shaft swing freely within an angle range of 10°, thereby the axial bending stress caused by the deflection of the borehole can be eliminated effectively.

这种装置采用类似球形关节的旋转机构，消除了抽油杆柱上下往复运动产生的倒扣扭矩；在短节下端设计有10°的内圆锥表面，使转轴能够在10°范围内自由转动，从而有效地消除了由于井身弯曲而产生的轴向弯曲应力。

No deformity of rotation, angulation and crispation occurred in 13 l imbs, but functional impairment occurred in 6 l imbs after union of fracture.

X 线片示13肢均骨折愈合，无旋转、成角及短缩畸形。6 肢因关节僵硬、瘢痕挛缩等，骨折愈合后遗留功能障碍。

Based on the improvement of exponential map, a novel motion parameterization method called Dual Exponential Map which can depict translation and rotation, linear velocity and angular velocity simultaneously was proposed.

对指数映射方法进行改进，提出一种双指数映射运动参数化方法，用于同时描述关节模型的平移与旋转、线速度与角速度。

Results: 13 cases with 19 bone broken points,the positions are at dens ,side plank of atlas,occipital,plank of axis,processus spinosus etc.23 cases with axis and atlas half dislocation.Of which,16 cases were with pure dislocation,7 cases with rotating dislocation,11 cases were with swollen at the side of vertebra,2 cases with depressing of vertebral artery,5 cases with continued narrowing of vertebral canal.

结果：13例共见19处骨折，部位分别为齿状突、寰椎侧块、枕骨、枢椎椎板、棘突等，寰枢关节脱位23例，其中单纯性脱位16例，旋转性半脱位7例，11例合并椎旁血肿，2例见椎动脉受压，5例继发性椎管狭窄。

In chapter 3, the control object of this subject, which is a three-link gymnastic robot on horizontal bar with limited joint torque and joint angle is brought forward and its mathematic model is developed. After simulating of the movement of the gymnasts, the control task of this subject is designed as a series swing-up and balance movement, the key point of control is analyzed.

第三章，提出本课题研究的对象：关节力矩和旋转角度受限的三连杆单杠体操机器人，推导了它的数学模型；提出要完成的控制任务：模仿体操运动员上杠动作而设计的摆起倒立动作，分析了这套动作的控制关键。

During steering maneuvers, the strut and the steering knuckle (through the ball joint and a pivot bearing in the strut's upper retainer) turn as an assembly.

车辆转向时，支柱以及转向关节（经由球形接头与上支柱固定器之轮毂轴承）会一体旋转。

Description: This project shall adopt the double-mixing-shaft reciprocal rotary distribution design, with the vibration excitation/isolation system to be floating-connected by double-seated spring and hydraulic system adopting highly-dynamic performance proportion, making unnecessary a separate motor for driving and ensuring high compactness of blocks. The machine should make less noise than similar products, operate quickly, reduce the impact upon change of direction and save energy. Each joint should be linked with knuckle bearing and provided with lubricating device to prevent wear and tear. The automatic control system should use PLC and HMI display of operation, providing accurate and explicit detection of faults.

内容说明：本项目采用双搅拌轴往复旋转布料设计，激振隔振系统采用双座双弹簧浮动连接，液压系统采用高动态性能比例，可使砌块成型机不需要单独电机驱动，能保证砌块密实度大；机台噪声比同类机台小，运行快速，降低变向时的冲击配备，节约能源；各关节部位均用关节轴承联结，具备润滑装置不易磨损；自控制系统选用PLC编制控制器，操作人机界面显示，故障准确明确。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。

Go down on one's knees;kneel down

屈膝跪下。。。下跪祈祷
