屈曲的

Central parts of mechanism of elevating and equilibrating were also processed static, dynamic, flectional analyses with finite element method by using Pro/MECHANICA. In the end, its dynamical model was built and simulated in ADAMS, dynamical responding of its hydraulic elevating part was analyzed, gun muzzles elevation disturbance in different fire angle and so on were obtained, work performance of mechanism of elevating and equilibrating was more studied.

使用Pro／MECHANICA对高平机的主要零件进行了有限元的静态、动态、屈曲等分析；最后在ADAMS中建立高平机动力学模型并进行仿真分析，分析其液压高低机部分在火炮发射时的动力学响应，获得了不同射角下由高平机引起的炮口高低扰动等数值，进一步验证了高平机的工作性能。

By some typical numerical examples , the effects of delamination , hygrothermal and the progressive failure on the stability behaviors of the AGS plate and shell are discussed. The numerical results indicate that the effects of delamination , hygrothermal and progressive failure on the stability of composite AGS structures can not be neglected when the above factors result in a jump of the buckling mode.

通过典型算例讨论了湿热环境、累积失效及分层损伤等因素对复合材料 AGS结构稳定性的影响，数值结果表明当上述因素导致结构的屈曲模式发生突变时，其对 A GS结构稳定性能的影响是不容忽视的。

There are more than two dozen reported cases of lumbar facet dislocation after rapid deceleration injuries (e.g., traffic accidents), most involving L5 S1.61,112 115 The mechanism of injury in these cases is purported to be a combination of hyperflexion, distraction, and rotation.61,112,116 In a posthumous study conducted in 31 lumbar spines of subjects who died of traumatic injuries,Twomey et al.117 found occult bony fractures in the superior articular process or subchondral bone plate in 35% of victims, and z-joint capsular and/or articular cartilage damage in 77% of cases.

多项研究报道了急性减速伤后发生腰椎小关节分离，多数发生于L5-S1，其机制可能为过度屈曲，分离和旋转。在一项对死亡病例的研究中，Twomey 等发现，31例因交通事故死亡的人中有35%的腰椎上关节突或软骨下骨性终板存在隐匿骨折，77%存在小关节囊和/或关节软骨损伤。作者总结创伤后隐匿性股和软组织损伤也许是腰痛的来源。

As true synovial joints,each facet joint contains a distinct joint space capable of accommodating between 1 and 1.5 ml of fluid, a synovial membrane, hyaline cartilage surfaces, and a fibrous capsule.21 The fibrous capsule of the lumbar facet joint is approximately 1 mm thick and composed mostly of collagenous tissue arranged in a more or less transversefashion to provide maximum resistance to flexion.22,23The joint capsule is thick posteriorly, supported by fibers arising from the multifidus muscle.

作为真正的滑膜关节，每个小关节包含明显的关节间隙，容纳1到1.5ml关节液。小关节由滑膜，透明软骨表面，和纤维囊组成。纤维囊厚约1mm，大部分有白色纤维组成，横向排列，以在屈曲时提供最大的张力。囊的后部很厚，纤维来源与多裂肌。

This changes are highly related to clinical injuries ,the more loss of prevertebral height is, the less canal occlusion, and the less loss of prevertebral height is, the more canal occlusion.

胸腰段是脊柱骨折的好发部位，由于其解剖结构的复杂及暴力作用的程度不同，因此在临床上可见到不同的骨折类型，主要多见垂直压缩型和屈曲压缩型两种，有的还合并脊髓神经损伤。

These findings indicate that this path of wrist motion confers a unique degree of radiocarpal stability and suggests that this direction, rather than the anatomical directions of wrist flexion-extension and radioulnar deiation, is the primary functional direction of the radiocarpal joint.

这些发现表明腕关节运动的轨迹以桡腕关节独一无二的稳定程度为对照的，这个方向是桡腕关节原始的功能方向，而不是腕关节屈曲及背伸及尺偏桡偏的解剖方向。

Results The computational results of force and pressure transmission through normal carpus matched well with previous studies. The release of TCL resulted in radial and palmar displacement of the scaphoid, flexion and radial rotation of radiocarpal joint as well as a further radial deviation of the whole carpal tunnel.

结果 腕部载荷传递及关节接触应力分布情况与前人实验数据相当接近；腕横韧带的切除导致舟骨发生向桡侧和掌侧的偏移，以及掌向屈曲和向桡侧的转动，而整个腕管结构则产生更大的桡侧偏移。

The skin lesions progressed with numerous grouped bullae, and erosions on a noninflamed base on the palms and soles which resulted in syndactyl deformities and flexion contracture of hands and feet.

皮肤的损害进展成许多的大水疱与手掌、足掌未发炎的糜腐蚀，导致手脚的并指畸形与屈曲挛缩。

Some authors studied the buckling problems of delaminates of laminated structures or laminated composite materials using finite element analysis and traditional beam/plate theories.

而用各向同性弹性体的有限变形理论研究脱层的屈曲问题的就比较少，所看到的文献中主要有Wang Wen-Xue~([26，27])，Loboda和Mityukova~([29])，Chiu和Erdogan~([32])等。
