滑动

The elastica deforms after it is subject to an external pushing force on the moving clamp. It is observed that when the pushing force reaches a critical value, snapping may occur as the elastica jumps from one configuration to another remotely away from the original one. Moreover, in order to transfer motion or force by this structure, we will make a research into the relation between longitudinal forces of the two ends.

在对滑动夹持端施以推力后，弹性板条会产生变形，我们观察到当推力达到临界值便会发生折断式挫曲的现象，由原先的变形跳至另一稳定的变形；此外，希望以此结构传递运动或力量，故将对两端的轴向力关系加以研究。

In the theoretical investigation, we calculate the static load-deflection curves and the longitudinal forces transmission for a specified angle difference between the fixed clamp and the moving clamp. To study the stability of the equilibrium configuration, we superpose the equilibrium configuration with a small perturbation and calculate the natural frequencies of the deformed elastica. In addition, the condition where two ends with identical angles are introduced will be researched.

在理论分析方面，针对几种不同的固定夹持端与滑动夹持端之夹角，计算出静态的受力-变形曲线以及轴向力传递关系；为了探讨平衡位置的稳定性，在平衡位置加上微小的简谐扰动，然后计算出弹性板条受力变形后的自然频率；此外，对於两端角度相同的情形，将有更深入的研究。

The stationary ring of the device is fixed on the cover of the pump, the rotating ring and the pump shaft are in the endwise slip connection. The elastic cell acts on the direction for the rotating ring to press the stationary ring, while the pump shaft outside the pump cover is hinged with the flying iron, of which the force transferring end acts in the direction for the rotating ring to deviate from the stationary ring.

Another six specimens of each group was obtained for biomechanical test at 8 weeks. RESULTS: There were no significant differences between control group and fibrin group. In bFGF group compared with control and fibrin groups, appearance of the angiogenesis, fibroblast proliferation and collagen production in the sheath, epitenon and parenchyma at repair site occurred earlier and were more in quantity, the gliding excursion of the tendon was shorter, and the work of flexion and the ultimate tensile strength of the tendon were greater.

结果：对照组与纤维蛋白封闭剂组间各项观测指标比较均无显著性差别，与对照组和纤维蛋白封闭剂组相比，bFGF组修复部位腱鞘、腱外膜及腱实质的新生血管形成、成纤维细胞增殖较好，胶原的分泌出现早，数量也较多；肌腱滑动距离较短，屈曲功和肌腱最大抗拉力较大。

After this process finishes, equiaxed and fine hard particles can slide and rotate in soft B2 matrix.
