Then we obtained the data of the lower limb motion of the volunteer in gait by motion capture system. Analyzing the results, we found that the relative positions of the landmarks which were used to construct JCS did not change much during the movement. That means the method on definitions of JCS in this article was reasonable at a certain range.

通过利用运动捕捉系统对自愿者步态过程中的下肢运动轨迹进行采集，分析构建坐标系的特征点在运动过程中空间相对位置的不变性，说明了文章提出的下肢关节坐标系定义方法在一定范围内是合理的。

It is also varified that completely unbent position is a only singular point in the whole workspace of a finger.

根据手指的运动特点和关节力矩传感器的配置情况，得到了手指的速度雅可比和力雅可比，并由此证明：手指完全伸直的位置是整个工作空间内唯一的奇异点。

Each of its 8 joints with 2-DOF was an universal coupling with "+" shape and their motion range is over ±60 degree."U" form components constructed two rotatory DOF that their rotary range was adaptive to human whist.

由两个 U形构件组成手腕的两个转动自由度，它们的运动范围与人的手腕运动范围相适应，在这个机构的工作空间内没有奇点，具有平动和转动解耦的特性，最后一个自由度是手控器手指关节的运动。

Suitable operation combination, bone shaft lengthening nearing bone end, keeping endosteal cortical bone osteotomy, and a continual lengthening of 1.0 mm.d- for adults and 1.5～2.0 mm.d-1 for children can get ideal limb length, quality and fast callus development and satisfactory joint function.

实施靠近骨端的骨干延长，保留内骨膜的皮质骨截骨，成人每天1.0 mm、儿童每天1.5～2.0 mm的连续延长，可获得理想的肢体长度、良好的骨痂生长速度和质量以及满意的关节功能。

实施靠近骨端的骨干延长，保留内骨膜的皮质骨截骨，成人每天1.0 mm、儿童每天1.5～2.0 mm的连续延长，可获得理想的肢体长度、良好的骨痂生长速度和质量以及满意的关节功能。

According to the first, intravertebral vacuum phenomenon is the result of vertebral osteonecrosis,8,14,17,18 whereas the second theory supports that intravertebral vacuum phenomenon signifies nonunion and pseudarthrosis of a vertebral fracture.20,21 A third theory, which did not find appeal, suggested that intravertebral gas could be of intradiskal origin, leaking to the vertebra through the fracture, since a high coincidence (86%) of intervertebral disk vacuum was noted in cases of intravertebral vacuum.6

第一种理论认为椎体内真空现象是椎体缺血性坏死的结果[8，14，17，18]，而第二个理论认为椎体内真空现象意为着骨不连和假关节[20，21]，另外目前还未广泛接受的第三个理论认为椎体内气体可能是从椎间盘中从椎体骨折裂隙中流入的，椎体内出现真空现象的同时伴有椎间盘内真空的比例很高（86％）[6]。

Results: Most synovial sarcomas located in the extremities close to joints. Synovial sarcomas detected by radiography typically appeared as round, oval or multilobulated juxtaarticular soft-tissue masses with calcification in some cases. The most common CT appearance of synovial sarcoma was heterogeneous deep -seated soft-tissue mass with attenuation similar to or slightly lower than that of muscle. On T1WI, synovial sarcomas typically appeared as prominently heterogeneous multilobulated soft tissue masses with signal intensity similar to or slightly higher than that of muscle. On T2WI, synovial sarcomas appeared as prominent heterogeneity with predominantly high signal intensity.

结果：大部分滑膜肉瘤位于关节旁；X线表现为圆形、椭圆形或分叶状软组织肿块，部分可见肿块内钙化；典型的CT表现为较深在的、等或稍低密度不均匀的软组织肿块；磁共振T1WI与肌肉信号相比，滑膜肉瘤表现为分叶状、不均匀、等或稍高信号，T2WI则表现为高信号为主的不均匀信号；DSA呈显著的肿瘤实体染色及新生血管。

And how high or low the belly sits depends on how much the pelvic joints loosen (thanks to a hormone called relaxin, produced by the ovaries mainly during pregnancy), thereby making more room for the baby to drop into the pelvis, he adds.

腹部位置的高或低取决于骨盆关节松动程度（由于荷尔蒙唤起耻骨松弛激素——主要是怀孕期间卵巢产生的），从而有更多的空间把婴儿丢进骨盆内，他补充道。

Failures of cementless cups include accelerated polyethylene wear, malfunction of the locking mechanism of the polyethylene liner in the metal-backed shell,59–62 and extensive periacetabular osteolysis.63 Screw holes in the shell enable debris to access the periacetabular cancellous bone, a further extension of the effective joint space.

非骨水泥型髋臼杯的失败原因包括聚乙烯磨损加速，金属杯中聚乙烯内衬锁定机制失效和广泛的髋臼周边骨溶解。金属杯中的螺钉孔为碎屑进入髋臼周围松质骨提供了通道和更广的有效关节容积。

Group 1 with fixation of facet joint screw had a significant increase in stiffness for extension, bilaleral bending, and colockwise rotation.

经侧后方斜向植入的单枚椎间融合器加上小关节突螺丝钉内固定融合术，在提供充分椎管减压的同时，具有损伤小、脊柱后部稳定性好、术中对马尾及神经根牵拉轻的优点，可以比较理想地取代后路双枚融合器椎间融合术。

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。
