In present study, we used the adult rabbits articular chondrocytes as the object of study, we researched the effect of TGF-β1 to promote chondrocytes proliferation and preserve the synthetise of special stroma in order to provide theortically and clinically basis of culture and proliferation in vitro of a-dult people articular chondrocytes.

材料与方法 1。成年兔关节软骨细胞分离、培养：取18月龄的成年日本大耳白兔1只，处死，片状切取关节软骨，解剖刀将软骨切成1.0mm~3大小碎块，消化，过滤，离心，收集关节软骨细胞，加入DMEM培养液(含20％胎牛血清、青霉素100U／ml，链霉素100U／ml)，调整细胞密度为2.5×10~5／ml，置于37℃，5％CO_2孵育箱内培养。

A shoe worn too big or too small will result in a stud being directly under the first MTP joint, affecting the joint as well as the sesamoids (the two small bones under the joint which protect it).

一个太大或者太小的球鞋的鞋钉会直接位于跖趾关节肌肉的下方，这样会对跖趾关节肌肉和籽骨(在跖趾关节肌肉下提供保护的2个小骨头)有不好的影响。

The method of centrifuge tube culture can be used as a constructing technique of tissue engineered cartilage without scaffold material.

结论在无支架材料条件下，采用离心管培养技术培养的人胚胎关节表面软骨细胞可以构建组织工程化关节软骨，而且接近正常关节软骨的形态和功能。

Experiments were carried out to verify the static model. Experimental results show that the experimental curve matched well with the simulated curve, and there was certain error between them (maximal static error is 0.035 rad). The error cause was analyzed. Then the experiments were carried out to measure the dynamic performances of the side-sway joint. Experimental results show that the step response time of the joint was about 2 s steady value's tolerance zone ?

完成了侧摆关节静态特性试验，试验结果与仿真曲线基本吻合，验证了静态模型的正确性，但存在一定误差（最大静态误差为0.035 rad），分析了误差原因；对侧摆关节进行了动态特性试验，试验结果表明对于不同的期望值角度阶跃信号，侧摆关节开环阶跃响应时间大约是2 s

Periarthritis of shoulder is a aseptic inflammation of the surrounding soft tissue of articulation of shoulder which symptom is mainly the articulation arthralgiaand motor functional disturbance.

所谓肩周炎，就是肩关节周围炎的简称。是肩关节周围软组织的无菌性炎症，以肩关节疼痛和运动功能障碍为主要症状。

It is often difficult to define the source of pain for most patients have referred somatic pain, in which neurological symptoms and signs are not so apparent.

但是患有腰椎小关节损伤的患者有时会有下腰部、大腿前方、腹股沟等部位疼痛，说明腰小关节的神经支配分的复杂性，腰椎小关节的这种支配方式形成了十分复杂的腰腿痛发病机制。

Secondly, for redundant robots with elastic joints, system model developing and the effect of redundancy resolution on joint torques and joint deflections are discussed.

其次，对考虑关节弹性的冗余度机器人进行了研究，主要讨论了系统的建模以及冗余度分解对关节力矩和关节弹性变形的影响等方面的问题。

In terms of the fact that Skinned Mesh Animations based on Matrix palette skinning does not work well for non-quasi-articulated objects, this paper presents a new technology for skin deformation, skinning arbitrary deformation,which can set proxy-joints,automatically construct skinning approximations for arbitrary precomputed animations,and use dual quaternion for skinning .

针对利用MPS驱动的骨骼蒙皮动画对于非关节的对象精度不高的问题，提出了基于MPS的任意变蒙皮，该技术在任意动画上设置代理关节，自动为预先处理的任意动画的每一帧构建蒙皮相似量，利用二重四元数蒙皮，实验表明，SAD不仅能够有效地驱动非关节元素对象提高精度，而且能够充分利用MPS的优点
