伸直

The result shows that the technical style of our athletes used is that stride length is shorter and stride frequency is larger,the buckjump time of our players is located at the floor level of the foul limit,the knee angel is unwind from touchdown on upright phase,in the sprint phase,the kneel angel is blurry from touchdown to upright phase,the uprightness displacement of body center and vertex are higher than the international athletes, this since stretching to leave a ground of opportune moment to be partial to early and making an effort action insufficiency with leg driving of the ankle joint relevantly, also with the leg put of front stretch is not enough active at the touchdown ground moment.

结果表明，我国运动员在后半程中，运用的是步长较短，步频较快的技术风格；腾空时间总体上处于犯规时限的下限，膝关节从着地瞬间直至垂直支撑面保持了可见的伸直状态，但在最后冲刺阶段，膝角出现了模糊伸直过程；身体重心垂直位移、头顶位置上下起伏均高于世界优秀运动员平均水平，这既与踝关节后蹬伸展离地时机偏早、用力动作不充分有关，也与着地瞬间摆动腿前摆后的前伸着地动作不够积极有关。

In the kinetic aspect, children with spastic diplegia demonstrated smaller maximal extension moment and power of knee joints than did typical children in the natural condition. In the loaded condition, both the maximal hip and knee extension moment increased and the maximal knee extension moment increased to the level of typical children.

於动力学方面，脑性麻痹儿童的膝关节最大伸直力矩和功率皆较一般儿童低；在荷重状态下，脑性麻痹儿童的髋关节和膝关节之最大伸直力矩都有增加，其中膝关节的伸直力矩提升到与一般儿童相当的程度。

Three hyperextension angles (0°, 5° and 10°) and axial tibial rotations (0°, 2.5° and 5°) were assumed to simulate different knee alignments.

在膝关节过度伸直分析中，模拟膝关节三种过度伸直角度(0， 5和 10度)同时伴随有膝关节轴向转动(0， 2.5和 5度)的受力接触状态。

RESULTS: The anterior cruciate ligament is composed of collagen fiber, and plays an important role in intorsion of the knee joint and straigh activity of tibia, limits tibial antedisplacement and excessive extension, and limits stability of medial knee and tibial rotation activity when knee strengthened.

结果：前交叉韧带由胶原纤维组成，对膝关节的内旋和胫骨的伸直活动起稳定性作用，限制胫骨前移及过度伸展，对膝内侧的稳定、膝伸直位时胫骨旋转活动限制作用。

Even though the range of motion was larger for the normal group than for the ACDF group, the intersegmental rotations at the adjacent C6-C7 and C4-C5 levels in the ACDF group were 13.4 and 8.8 compared with 3.7 and 4.8 in the normal group, respectively, during the neck motion from 20 flexion to 15 extension.

结果：纵使正常组的活动范围比颈椎前路减压和融合活动范围要大，后者的颈椎6-7和颈椎4-5椎间的旋转在颈部20度屈曲时为13.4度和在颈部15度伸直时8.8度，相比正常组的颈椎6-7和颈椎4-5椎间的旋转在颈部20度屈曲时为3.7度和在颈部15度伸直时4.8度。

Seven of them were done in the presence of 3 kg hip traction, and six were in 5 kg hip traction （4 cases after 3 kg traction）. Angiography was also performed in a intorted position without traction in 5 patients. In 3 cases, retinacular artery angiography was done simultaneously using the microcatheter.

造影在下列条件下完成，（1）中立位无牵引（9例）；（2）中立位3kg牵引（7例）；（3）中立位5kg牵引（6例，其中4例先行3kg牵引）；（4）伸直内旋位无牵引状态下（5例），3例用微导管同时作了支持带动脉造影。8例作了正常髋关节中立位无牵引状态下血管造影，其中2例加做下肢伸直内旋位时造影。

Two arms reach the top of your head and be unbended, the whole body should look like a straight line.

两头起：仰卧，头部略微抬高，双腿水平伸直，但不接触地面，双臂向头上方伸直，身体成水平的&一&字型。

He stretched his legs, stretched on the beside chair; he watched his jeans and sneaker, he dived into his unironed suit to felt for some coin, four on the left, six on the right, some of which are small, may be not the same face value, he surmise.

他把脚伸直，在旁边的椅子上伸直；他看他的牛仔裤、帆布球鞋，他摸他皱巴巴的小西服里的硬币，左边四个，右边六个，其中有几个小的，应该不是一个面值的，他想。

For joint moments, hip extensor and abductor were found to be greater in the elderly during upslope walking with relatively smaller knee extensor moment and ankle plantarflexor moment.

对於关节力矩，髋伸直和外展力矩在老年人上坡时明显大於年轻人，但此时的膝伸直力矩及踝跖屈力矩较小。

If you reach out to the side, or reach out in front of you, the arm straightens and loses leverage.

如果你向侧面伸直，或者在身前伸直手臂，你的手臂就会失去这个杠杆作用。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
