RESULTS:In vertebral pulp extirpation group, the stress was proved to be the highest at superior edge, posterior middle part, lower edge and anterior middle part of small joints under anteflexion, backward extension, compression, lateroflexion and revolving states, moreover, small joint stress in artificial lumbar intervertebral disk was higher than that in normal intervertebral disk, but obviously lower than that in vertebral pulp extirpation group;however, the small joint of the middle part of artificial lumbar intervertebral disk bore the highest stress under revolving states.

结果：髓核摘除组小关节的上边缘部、后中部、下边缘部和前中部在前屈、后伸、压缩、侧屈、旋转状态应力最大，人工腰椎间盘组的小关节的应力比正常椎间盘高，但明显小于髓核摘除组，但正中部在旋转状态下，人工腰椎间盘小关节的中心部位承受的应力最大。

磁磁棒棒条的轴与中心轴成一角度，并围绕它旋转的轴与中心轴成一角度，并围绕它旋转。。

But if one of the partners were much heavier, say a father twirling round his daughter, then the centre of mass that they both spin around would be pulled closer to him and he would move much less, as the girl spins around him.

但是，如果其中一个合作伙伴更重了，说一个父亲捻转轮他的女儿，然后该中心的质量，他们都旋转将退出接近他，他将移动少得多，因为他周围的女孩旋转。

Among these features are: absence of the nuclear rotation and development of the centriolar complex and the initial region of the axoneme in a position directly perpendicular to the basal pole of the nucleus and presence of numerous thick anchoring fibrils connecting the proximal centriole and the proximal part of the distal centriole to the nucleus.

其特点主要是：生精过程中不发生细胞核的旋转，中心粒复合体和轴丝起始段直接发生在核的基底面垂直线上，有无数的粗的固定纤维将近端中心粒和远端中心粒的近侧部连接到细胞核上。

Rotate the Fork to the right, and rotate the Handlebars to the left; then insert the Steering Rod into the Rear Steering Rod Connector as you rotate the Handlebars and Fork back toward center.

旋转叉的权利，并旋转扶手的左侧；然后插入指导棒到背杆连接指导你旋转扶手和叉回中心。

It is shown from this thesis that flow fields on synoptic maps can be decomposed into rotation and deformation fields. Geostrophic non-frictional cyclone and anticyclone vortex patterns are closed circulations around the center point, streamlines of frictional cyclone and anticyclone patterns have spiral forms around the focus point. Saddle fields have four vortex centers (two cyclones and two anticyclones) and a saddle point. Blocking high pressure and cut-off low pressure patterns consist of a vortex center and a saddle point.

本文说明了天气图上的流场可以分解为旋转场和变形场：地转无摩擦的气旋、反气旋的涡旋型式是围绕中心点的闭合环流；考虑摩擦的气旋、反气旋的流型是围绕焦点的螺旋型式；鞍型场有4个涡旋中心点（2个气旋和2个反气旋）与1个鞍点；阻塞高压和切断低压由1个涡旋中心点与1个鞍点组成。

Methods 1038 eyes of 606 consecutive myopic patiences who had bilateral Custom Vue LASIK between March 2006 and August 2006 were involved in the study. Wavefront measurement and iris registration were performed in the upright position with Wavescan aberrometer, then more over iris registrations were performed in the supine positon during the operation with VISX Star S4 IR.

选择成功接受波前像差虹膜定位LASIK手术的近视患者606例1038眼，术前应用Wavescan像差仪取坐位行波前像差检查和虹膜识别，术中应用VISX Star S4 IR手术，记录眼球旋转及瞳孔中心移位，对前后眼球旋转及瞳孔中心移位进行比校。

A two-times locating method based on the gray contrast of surroundings is presented in locating central reference point. This method has better adaptability and robustness, and can basically meet for the accuracy of automatic locating center. Fourier spectral analysis is improved to obtain a more accurate ridge frequency in computing ridge frequency. The average ridge width is used in designing Gabor filters, so the filters have certain adjustability. The rotating invariance of fingerprint images is solved by the rotating of feature models in feature matching.

在中心参考点定位部分，提出了基于局部邻域灰度对比度的二次定位方法，该方法具有较强的适应性和鲁棒性，基本满足自动中心定位的准确度要求；在频率域估计中，改进了傅立叶谱分析法，提高了纹线频率计算的准确度；引入平均纹线宽度作为Gabor滤波器的设计参数，使滤波器具有一定的自适应性；在特征匹配阶段，通过对特征模板的旋转解决指纹图像的旋转不变性问题。

Figure 9-45 indicates a universal dividing head, which consisits of the body, the swivel block, the woekpiece (with one of its ends supported by the center of the work spindle) is rotated through the desired angle by rotating the index crank through an angle that is dependant upon the desired angle.

图9-45显示一个普遍的分度头，其中consisits的机构，旋转座的woekpiece （同一个目的支持中心的工作主轴）是理想的旋转角度，通过旋转该指数通过一个曲柄角度取决于所希望的角度。

An auxiliary power motor with improved structure includes wheel shell, rotor ring, stator plate, central wheel axle and control circuit.

一种改良结构的辅助动力马达，包括轮壳、转子环、定子盘、中心轮轴及一控制电路，转子环的内环面埋设磁铁，定子盘周围固设环形矽钢片，其外环面具有多个T形齿牙，其齿数为非转子环磁铁数的公倍数，矽钢片设有三相星形线圈绕组，且于定子盘电机最佳启动角度处设有霍耳元件组；借此将定子盘固设于中心轮轴，令轮壳夹设住转子环并套设于中心轮轴两侧，当转子环旋转时，即可降低磁极间的钝齿转矩，令电动车行进更加顺畅无噪音。
