掌握肩关节前脱位，肘关节后脱位，桡骨头半脱位，髋关节后脱位的临床表现，诊断及治疗。

Three kind of different cross stride distance of the pivot foot most push-off forces, will increase along with the cross stride distance increase.

、跨步距离77%的身高比率时其最大躯干旋转角速度及最大髋关节角速度所发生的时间较早。

Has become a specialist and one of the worldwide leading manufacturers of gear hobbing and worm milling machines, thread milling and thread whirling machines, honing machines for heads and inserts as well as machines to produce dental burs with more than 40 years experience in the development of machine tools and special machines.

瑞士莫尼埃查纳有限公司现已成为世界领先的齿轮切削机床、蜗杆螺纹内旋风和外旋风铣削机床、人工髋关节内外球面珩磨机床、牙科车针机床制造商之一，拥有40余年特种机床设计与制造的经验。

Rnage-of-motion testing reveals limitation of terminal flexion and extension in the involved knee joints and internal rotation in involved hips.

活动范围试验显示受累膝关节不能完全屈曲和伸直，髋关节内旋受限。

The kinematics speed was detected under different state of simulating the driving moment of hip joint and the damping moment of knee joint. The testing results indirectly built the dynamics relationship among the inertial force, damping force and the swing speed of the knee joint.

在模拟不同人体髋关节摆动驱动力和膝关节阻尼力的状态下，测量膝关节阻尼缸的运动速度，从而间接获得了假腿阻尼力、惯性力与膝关节摆动速度之间的动力学关系。

According to swinging the angle change of leg joint, hipjoint corner change in start stage withdraw knee stage start to have a prominent crestthe end curve, the overall range that increases is 14.3°士 5.0°;According to anglechange of knee joint , swing leg minimum knee corner average 84.3°士 7.6° withdrawknee.

从摆动腿关节角变化来看，髋关节角变化曲线在启动阶段末提膝阶段始有一个显著的波峰，总体增大的幅度为14.3o士5.0o；从膝关节角度变化来看，摆动腿提膝时最小膝角平均值为84.3°士7.6o。

In addition, the hip joint moment of unhealthy limbs in frontal plane was 0.12 N-m/kg higher than healthy limbs. At swing phase, knee joint flexion was 7 degrees higher than the unhealthy side and 3 degrees adduction in frontal plane.

摆动期健侧膝关节弯曲角度比患侧多出7度，冠状面上之髋关节内收角度比患侧多出3度；两侧臀中肌作用力患侧明显较小，致使骨盆下垂角度较大，身体重心向患侧偏移。

The results indicate that weight factor had significantly effect on gait speed, steps per minute, gait cycle time, the ratio of stance time and swing time, maximal flexion angle of knee joint and the range of motion of elbow joint. Shelf height had significantly effects on hip flexion and elbow ROM. Box size factor had significantly effect on stride length, gait cycle time, the ratio of stance time and swing time, knee joint elbow ROM. For the muscle activity levels with EMG, load weight and shelf height both affected the %MVC significantly. When the subjects carrying a load of 14kg, the muscle activity and the subjective body part discomfort rating are both higher than that of 7kg. The box size had effect on the body part discomfort rating of upper extremity and back. For the kinetic and kinematics analysis, the shelf height around elbow height was better than the other two height levels.

研究结果显示，对步态时间与空间参数而言，重量因子显著影响步速、步频、步态周期时间与站立期摆荡期比值，箱型因子显著影响步长、步态周期时间与站立期摆荡期比值；关节活动度而言，重量显著影响膝关节最大弯曲角度、肘关节屈伸角度范围，高度因子显著影响髋关节前后倾角度、肘关节活动各变项，箱型因子影响膝关节弯曲最大最小值以及肘关节活动各变项，对肌肉活动度而言，重量与高度因子皆显著影响MVC%值，14公斤重者肌肉活动度与主观不舒适程度皆较7公斤者高，箱型因子虽无明显影响肌肉活动度，但是在主观不舒适程度上却明显影响上肢与背部，终点放置高度应设在肘高附近为佳。

Therefore excess body weight and increased physical actiity add significantly to the forces that act to loosen, bend, or break the stem of a femoral component.

因此，身体过重和体力活动过量可明显增加髋关节受力，从而导致股骨假体的松动、弯曲或柄的折断。

The following total hip arthroplasty is difficult due to the residual fractures and the screw holes in the proximal femur which correspond to structure weakness, possible loosening of the femoral implant and artificial stem break through.

而若使用DHS治疗失败后，通常后续治疗以置换人工髋关节为主，然而此类患者却因DHS移除后会在股骨残留螺钉固定洞口，使得股骨结构强度减弱并导致人工关节长度的选用不易，使用不当则会造成骨干骨折、人工关节穿刺等。

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。

Cell morphology of bacterial ghost of Pasteurella multocida was observed by scanning electron microscopy and inactivation ratio was estimated by CFU analysi.

扫描电镜观察多杀性巴氏杆菌细菌幽灵和菌落形成单位评价遗传灭活率。
