There is great suitability of C(subscript 2/3) transarticular screw fixation, and it could be used as an alternative screw anchor point for posterior cervical instrumentation.

经C(下标 2/3)侧块关节进行螺钉固定在解剖学上是可行的，可以作为枢椎后路螺钉固定的补充方法。

The results show that the zero speed point is located on the arc between two absolute speed zero points of rotation axes, and the necessity of relative speed zero point is demonstrated, From the location of speed zero point, some useful conclusions can be drawn.

对速度零点的位置进行了分析，得出了如下结论：对于一定形状的工件，通过调整两轴的转速比以及两轴夹角参数，可以将速度零点置于工件之外，从而避免速度零点对研磨的不利影响。

With the help of computer program, zero speed point was searched. The results show that the zero speed point is located on the arc between two absolute speed zero points of rotation axes, and the necessity of relative speed zero point is demonstrated.

利用程序对相对速度零点的位置进行搜索，发现速度零点处于两轴绝对速度零点之间的圆弧上，从而证明了相对速度零点存在的必然性。

Firstly gives a definition of non standard accumulation point closure, and then compares it with the standard accumulation point closure, some properties of non standard accumulation point closure are discussed.

给出了非标准聚点的定义，并与标准聚点定义作了相应比较，讨论了非标准聚点的若干性质

Optimal screw path length: The distance from the optimal entrancepoint to the optimal vent point Screw tail distance: The distance between left and right optimalentrance point Transverse section angle: Half of the included angle between left andright optimal screw Sagital section angle: The average of angle between both side optimalscrew with the upper terminal plate 1.2.2 Modify the threshold of CT value to distinguish the rear partof the lumbar, Observate the the optimal entrance point and the adjustable range.

1.2.2三维重建观察螺钉最佳进钉点的位置和各方向螺钉进钉点关系，调整CT值下限阈值使椎弓后部结构尽量显示清晰，以利观察。 1.3统计方法本实验采用SPSS13.0统计软件。对同一椎体左右两侧椎弓根螺钉相对数据行计量资料配对样本t检验，对男女组间相关数据行计量资料独立样本t检验，对男女组内不同腰椎节段间相关数据行单向方差分析及不同腰椎节段间LSD法多重比较。

SIFT（Scale Invariant Feature Transform） local feature is chosen because of its scale invariance and the property of accurate key-point localization.The Euclidean distance between different SIFT feature vectors is defined as the measure of similarity to get the pre-matched key-point pairs.The affine transform model is used to realize the registration.In order to get the accurate affine transform parameter,the principal of affine transform error is used to get rid of mismatched key-point pairs from the pre-matched pairs.

该方法选取具有良好尺度、旋转不变性以及精确特征点定位能力的SIFT局部特征，使用其特征向量间的欧氏距离作为相似性度量进行特征点匹配，并依据仿射变换误差准则去除奇异匹配特征点对，采用仿射变换的几何模型，实现了遥感图像的快速自动配准。
