Result The flexibility of the scaffold material was powerful. The load-elongation curve of the mechanical testing was similar to that of ACL, the maximum load, the ultimate stress and the Young's modulus of the scaffold materials were 52.61 N, 14.96 MPa and 202.08 MPa respectively. Human ACL cells displayed the representative characteristercs of the ligamentous fibroblasts, and synthesized extracellular matrix, such as type Ⅰand Ⅲ collagen protein. The scaffold materials had no cytotoxicity. Human ACL cells adhered, grew and proliferated well both on the surface and in the holes of the scaffold materials.

结果］韧带支架材料的柔韧性强，拉力测试的负荷－拉伸曲线与韧带的拉伸曲线相似，其最大负荷、极限应力和弹性模量分别为52.61N、14.96MPa和202.08MPa；体外分离培养的人前交叉韧带细胞呈典型的成纤维细胞特征，能在体外分泌Ⅰ、Ⅲ型胶原等细胞外基质；支架材料无细胞毒性，人前交叉韧带细胞可在支架材料上黏附、生长并分泌细胞外基质。

Weiss, MD, from Orange Park, Florida, generally commends the procedure, but he notes that it involves removing normal skin and that there is no evidence that a suture line located paramedian to the cleft experiences any less stress, strain, or shear than a suture line in the cleft.

Weiss博士在评论中表达了对这个手术疗程的推崇，但也特别指出，这个手术不但会动到正常的皮肤，也没有证据显示位於中线旁的缝线会比裂缝上的缝线受到较小的压力、拉力、或撕裂的力量。

The flexible shafts have better strength and rigidity than ordinary level, they are ideal substitute for conventiona level and universaljoint with such merits as : light weight, good flexibility, easily crooking, compact constru—ction, easily installation, good seal, proof rust and anti—deformation, neatly operation.

工作原理：机械操纵系统中的连接部位受力位移时，软轴的芯轴受力，产生往复运动，形成拉力、推力驱使机械作换挡、取力、升降、行走、加油、熄火、制动、转向、换向等工作，它不但优于一般杠杆的强度、刚性而且重量轻、柔性好、可弯曲、结构紧凑、安装方便、密封性好，不易锈蚀变形，操作轻便灵活，是替代传统的连杆、万向节机构的理想产品。

The companion galaxy's pull would be inducing extra starbirth by compressing gas, jump-starting the process by which stars form.

伴星系的拉力会以压缩气体的方式引发额外的产星活动，气体的压缩正是恒星形成过程的开端。

The key problem of uplift piles in deep buried substructure compared to underground engineering with shallow bury depth is how to reflect the influence of deep excavation off-loading on the uplift piles' bearing characteristic and capacity....

与浅埋的地下工程相比，该深埋地下结构抗拔桩设计面临的特殊问题是如何反映如此大体量深层地下开挖卸荷对抗拔桩承载特性的影响，主要表现在：深埋地下结构抗拔桩地面试桩开挖段侧摩阻力的扣除；开挖卸荷后桩周土体围压减小对桩基承载力削弱的影响；开挖卸荷基底隆起对桩产生的预拉力。

They also feature a lanyard for optimum comfort and a secure fit around your neck - the safety catches will release the lanyard if they are overstrained.
