This study is using LS-DYNA3D explicit finite element software to investigate that the head-cervical spine model with/without the helmet model, impact to the plane of ±15° angel in 3.2m/s, and to observe the cervical spine and head kinematics, to analyze the stress of vertebras and disc.

本研究应用LS-DYNA3D显式有限元素软体，使用完整的头-颈椎模型分成有无佩带安全帽部分，以初速3.2m/s模拟撞击角±15°时，颈椎的动态反应，观察颈椎与头部的运动，分析椎体与椎间盘的应值。

AbstractObjectives1 Correlate bone mineral densityto vertebral compressive strengths.2 Consummate the technique for percutaneous polymethylmethacrylate vertebroplasty and observe the pattern of PMMA imaging distribution.3 Determine the strength and stiffness of osteoporotic with or without vertebroplasty with PMMA bone cement.4 Correlation of BMD,insertion torque and pull-out strengths of pedicle screws.5 Ascertain whether augmentation with PMMA bone cement can enhance pedicle screw fixation in the osteoporotic spine.6 Ascertain whether augmentation pedicle screw fixation with PMMA bone cement can enhance the stability of unstable thoracolurner burst fractures of osteoporotic spine.

目 的1、测试椎体压缩强度，分析强度与骨矿物质密度（bone mineral density，BMD）的相关关系。2、观察经皮椎体成形术后聚甲基丙烯酸甲脂（polymethylme- thacrylate，PMMA）骨水泥在椎体内的形态学分布及影像学表现。3、比较PMMA骨水泥骨质疏松椎体成形术前/后椎体最大抗压力和压缩刚度的变化。4、分析椎体BMD、螺钉最大旅入力矩和最大拔出力三者之间的关系。5、分析PMMA骨水泥强化骨质疏松椎弓根螺钉后的螺钉的最大轴向拔出力和拔出刚度的变化。6、评价PMMA骨水泥强化骨质疏松椎弓根螺钉脊柱内固定对不稳定型胸腰椎损伤的即刻稳定性和反复载荷后的稳定性。

RESULTS: Following three approaches of lumbar interbody fusion, the stability of lumbar spine was significantly reduced, which was enhanced after bilateral pedicle screw fixation (torsion indexes were also increased). In addition, rigidity of the lumbar spine was enhanced.

结果：行3种单纯椎间融合后，腰椎的稳定性能明显下降，附加了双侧椎弓根螺钉固定后，腰椎的各项稳定性指标均增强，包括扭转力学指标也得到了很大增强，有效增加了腰椎的刚度。

Because of special geometry structure of three-cone bit, the top of formation will form a tri-spine well bottom while drilling with three-cone bit the drill string. It is the tri-spine well bottom that leads to the axial harmonic of vibration when the bit revolves a round and the three concavo-convex heave of bit and formation result in one time (1×rpm),two time (2×rpm), three time (3×rpm) turning table speed.

高岩由于三牙轮钻头的特殊几何结构，钻进过程中在岩层顶部容易形成一个三脊状井底，正是这一三脊状井底，当钻头旋转一周时钻柱轴向三次凸凹变化，由此在轴向产生1倍、2倍和3倍及其更高次倍于转盘转速rpm的谐波振动。
