伸直

Leonardo is clearly illustrating Vitruvius De Architectura 3.1.3 which reads: The navel is naturally placed in the centre of the human body, and, if in a man lying with his face upward, and his hands and feet extended, from his navel as the centre, a circle be described, it will touch his fingers and toes.

7达芬奇在《维特鲁威的建筑》第三章第一节第三小节中清楚地写道：肚脐很自然地位于人体的中央，如果一个人仰面朝天躺着，手脚伸直，以他的肚脐为中心可以画一个圆，他的手指和脚趾会在圆周上。

If you can hold the racquet in the continental grip and stick the arm almost straight in front of you (non-playing hand hold the throat of the racquet), you can be a quick volleyer.

假设您能够用大陆式握拍法握拍，然后把手臂伸直到身体前方，非握拍手轻轻握住拍喉处（Y 处，racquet throat），您就能学会快速截击手。

S white rabbits as our study ob jects, we built some OA animal mode by fixing the rabbits left posterior knee joint in st retching state into plaster casts for 8 weeks. After imposing active movement, p assive movement, active-passive movement and free movement on the knee joint, we have made an X-ray examination of the knee joint, and tried to observe the chan g e in the movement degree of the joint and in the biomechanics features, we also observed the influence of movement upon the morphology of arthrochondritis.

以新西兰白兔为研究对象，采用左后膝伸直位管型石膏固定8周的方法建立OA 动物模型，通过施加主动活动、被动活动、主动加被动活动，自由活动等运动处理因素，观察X线检查、关节活动度、生物力学特性和软骨组织的形态学改变。

The triceps muscle straightens the forearm at the elbow joint; the brachialis and biceps muscles bend it.

从肱骨到尺骨的三头肌是要使前臂从肘关节处伸直，屈肌则是使手肘弯曲。

The triceps muscle straighten s the forearm at the elbow joint; the brachialis and biceps muscles bend it.

从肱骨到尺骨的三头肌是要使前臂从肘关节处伸直，屈肌则是使手肘弯曲。

Methods One normal adult male was choosed, and his left elbow joint performed in pronation and extention position was scanned by spinal CT, and the two-dimensional image was dealed with Mimics 1 0 software, the three-dimensional finite element model was built up by Abaqus 6.7 software. Finite element calculation was performed to simulate the impact of 1 000 N on the elbow joint, and the stress distribution in the radial head and coronoid were analyzed.

选取1名正常成年男性为研究对象，使其左肘关节处于旋前伸直位，行螺旋CT断层扫描，得到CT数据二维图像，采用Mimics 10.0软件系统处理，利用Abaqus 6.7建立肘关节三维有限元模型，模拟施加1000 N冲击载荷，分析冠状突及桡骨小头内应力分布情况。

Penile straightening was adopted for incomplete epispadias and penile lengthening for complete and complex male epispadias.

对不完全型男性外生殖器作阴茎伸直术；完全型和复杂型作阴茎伸长术。

刺桐花花序硕长，花瓣粗尖硬，形状如辣椒，&刺&的感觉尖尖俏立着，一丛丛的花瓣如手掌伸直的五指，极富个性。

Gait:The Siberian Husky's characteristic gait is smooth and seemingly effortless. He is quick and light on his feet, and when in the show ring should be gaited on a loose lead at a moderately fast trot, exhibiting good reach in the forequarters and good drive in the hindquarters. When viewed from the front to rear while moving at a walk the Siberian Husky does not single-track, but as the speed increases the legs gradually angle inward until the pads are falling on a line directly under the longitudinal center of the body. As the pad marks converge, the forelegs and hind legs are carried straight forward, with neither elbows nor stifles turned in or out.

步态：HUSKY的特有的步态是平稳的并且不费力气的，他脚步轻盈并且快，在Show时，他的一种步态会以一种放松的适度的快速小跑，来展示他前躯很好的伸展性和后躯强大的驱动力，当HUSKY在慢跑时，我们可以从前面看他们的后面，并不是一条单独的轨迹，但是一旦他们开始加速跑时，他们的腿逐渐开始立即追赶前面落下的脚掌，直到形成一个纵向的并且落脚点为身体的中心点的时候，当步伐集中为一点时，前肢和后肢迅速的向前伸直，肘关节和后膝关节既不向外也不向内。

If you tend to hyperextend, typical calf and hamstring stretches done with a straight knee can aggravate the problem unless you take care to engage your quadriceps.

如果你已经有超伸的情况，那伸直膝盖做小腿和腘绳肌的拉伸会加剧超伸的情况，除非你同时收紧你的股四头肌。
