The marginal division was a flat fan-shaped structure with a volume of (0.48±0.02) mm3, a maximum rostral-caudate axis of 1.6 mm, a maximum dorsal-ventral axis of 2.158 mm, and a widest axis (the diameter at lateral-medial coronal brain section) of 0.17 mm. The marginal division also moved progressively externally from the rostral section to the caudate section, but its scope was larger than that of others. The whole marginal division changed evenly from the rostral section to the caudate one. Its flat structure widened progressively and its dorsal-ventral diameter narrowed gradually and became plate-shaped.

边缘区呈现一个片状扇形结构，体积为(0.48±0.02) mm3，最大嘴尾径为1.6 mm，最大背腹径为2.158 mm，最大内外径为0.17 mm；同尾壳核和苍白球一样从嘴侧到尾侧随着脑平面的增宽边缘区亦逐渐向外侧移位，其移位的幅度亦明显大于脑平面增宽的幅度；整个边缘区从嘴侧到尾侧呈均匀变化，其片状逐渐变宽，长度逐渐变小，从而形成一个盘状结构。

In order to decrease the weight of tracking system and make suitable use of the Lander space, the pitching-axis of Lunar optical telescope is vertical with the Lander's flank, its rotation part is fastened on the Lander's flank, the azimuth-axis adopts rotation reflecting mirror, the flat mirror is located before the telescope tube, the angle of flat mirror and the telescope ray-axis is 45°,so that the reflecting ray can enter the telescope optical system, the scan of the mirror can be accomplished by the rotation of the telescope tube.

工作过程中望远镜支架的两个轴需带动望远镜一起转动，为了减小跟踪平台的重量和合理利用着陆器空间，又能在大范围内对太空目标进行跟踪，月基天文望远镜的俯仰轴垂直于着陆器的侧面，其转动部分固联在着陆器的侧面，方位轴采用旋转反射镜方式，将平面反射镜放在望远镜的镜筒前端，并与望远镜光轴成45°安装，使反射光线能够进入望远镜光学系统，通过转动望远镜镜筒使得反射镜实现对空间的扫描。

Approach: the surface rust with sandpaper lighting, using raw materials with after winding into ring for emergency action to deal with, the best method is for-axis, or axis setting processing sets to restore the size of the original axis.

处理办法：锈蚀表面用砂纸打光，用生料带缠绕后，放入动环作应急处理，最好的方法是换轴，或轴镶套后加工恢复到原轴的尺寸。

From the simulations, we can see the distributions and transmission of strain and stress in model under different loadings, and the results explained the fractures very well. 4. Similarly, a axis FEM model was constructed to simulate the axis fracture, emphasized on the odontoid process. Three kind of odontoid process fracture were analysed on this model, which occurred respectively on the tip, the middle and the fundus. The results gave the best angle to fracture the odontoid process of the axis.

四、建立了枢椎的三维有限元模型，对枢椎齿状突骨折机理进行了理论上的研究，重点针对临床上齿突骨折的三种分类：1、齿突尖骨折；2、齿突腰部骨折；3、齿突基底部骨折，赋予齿状突在矢状面沿各种角度下受力条件，模拟衰椎前弓、襄椎横韧带以及CZ－3棘间韧带对枢椎造成的暴力破坏，确定了最可能引起齿状突暴力骨折的受力角度。
