The results showed that the tensile strength,the tensile modulus and the shore A hardness of CO all increased by raising of the temperature and prolonging the time,while the tear strength,the tensibility,the tensile set at break and the compression set of CO all decreased,and the hardness,the tensile strength,the tensibility,the compression set all tended to the bala...

结果表明，二段硫化温度越高，硫化时间越长，胶料的拉伸强度和定伸应力越大，硬度越高；而撕裂强度、伸长率、拉断永久变形以及压缩永久变形越小，其中胶料的硬度、拉伸强度、伸长率、压缩永久变形在一定时间后基本上趋于平衡，较好的二段硫化条件为150℃～160℃×3～4h。

Methods: 7 calf lumbar spine specimens (T13~S2) were biomechanically tested under pure moment of 10Nm loading with Tenor pedicle screw system as the fixation device. Range of motion and intradiscal pressure were measured in all unfused segments and compared among the control group, the single-segment-fixed group (L45) and the double-segment-fixed group (L3~L5), and the correlation analysis and comparison between the increments of kinematic index and intradiscal pressure were performed.

取7具小牛腰段脊柱标本(T13~S2)，以Tenor椎弓根螺钉系统作为固定器械，在10Nm纯力矩加载下进行生物力学测定，测定各活动节段的运动范围和椎间盘内压，比较完整对照组、L45单间隙固定组和L3~L5双间隙固定组间上述指标的变化，并对运动学指标和椎间盘内压增量进行相关分析和比较。

Less difference in stability was observed than was predicted between specimens receiving multilevel discectomy versus multilevel corpectomy, regardless of whether specimens were left unplated, plated anteriorly, or fixated with combined anterior/posterior instrumentation.

标本接受多节段椎间盘切除与多节段椎体切除之间观察到的稳定性上的差异，比预想的要小，无论是没有进行钢板固定的标本，还是前路钢板或联合前后路内固定者都是如此。

Baziling forked tunnel along Shanghai-Chengdu Expressway in construction is an unsymmetrically loaded tunnel. Construction process of forked tunnel is very complex because the forked tunnel includes twin-bore section and small clear spacing section. So, it's important for forked tunnel to adopt appropriate construction process.
