Methods: Injured patients of cervical spine was cayyied on X-ray inspection.,then according to the result of ADI and LADS ,next to CT or MRI inspection ,and that was to guide clinical diagonosis and treatment.To observe atlanto-dental interval (anterior arch of atlas posterior border to odontoid process anterior border) and odontoid process caster(included angle between axis of ordinate of odontoid process and axis of ordinate of odontoid vertebra) on the X-ray lateral projection.

对有颈部外伤史的病人常规行X线检查，然后根据寰齿间距和齿突侧块间隙的结果，行下一步CT检查或者MRI检查，指导临床治疗方法的选择。X线侧位片观察寰齿前间隙(为寰椎前弓后缘与齿突前缘距离)，齿状突后倾角(齿突纵轴与枢椎体纵轴的夹角)；开口正位片上测定齿突侧块间隙。

A novel cable climbing robot applied to cable maintenance was introduced. It is centered orientable wheel-based, omni-directional cable climbing robot. The climbing mechanism of the robot and its working process were described. The driving force needed was analyzed, and the critical force needed for maintaining robot staying cable was calculated. The eccentricity allowed between center of robot and cable axis when the robot moving on inclined cable was discussed, and the least eccentric magnitude was calculated.

提出了一种应用于缆索维护的爬缆机器人机构实现方案，该机器人采用中心可转向的轮式驱动；介绍了机构组成及工作原理，在建立缆索曲线约束模型的基础上分析了机器人的驱动力，计算出了机器人能够在斜缆上工作所需要的临界驱动力；讨论了机器人在斜缆上工作时机器人轴和缆索轴不重合而出现偏心的原因，提出了减小偏心的方法，并计算出了为保持机器人对斜缆的适应性所需要的最小偏心量。

It is shown that some important concepts about Gaussian beam in the paraxial theory cannot apply to the off-axis Gaussian wave.

结果表明，傍轴光学关于高斯光束的一些重要论断，对远轴高斯波不再适用。

The Ploughshare mixing tools have been designed especially for ore mixing. The mixing tools disperse the product, create a rubbing effect and return the product in axial direction, which is essential for accurate mixing.

犁铧式的混合工具为矿石混合特殊设计混合轴分散物料，产生物料运动效应，再把物料带回轴的方向，这对精确的混合是很必要的。

First, normalized polar coordinate translation is carried out in the shape region with an origin at the middle of the region and a polar axis of the longest region orientation axis. Then, interval operations are defined between inner point intervals of the region at the same orientation.

该算法首先以形状区域的中心点为极点，区域的最长轴方向为极轴，对形状区域进行归一化的极坐标变换；然后定义了同一角度对应的区域内点区间之间的运算；最后定义了两个区域归一化极坐标变换结果在区间运算下的相似度函数，用以表征两个区域之间的匹配度。

Since polar organic crystals have noncentric structures, the existence of polar axis in the crystals has a significant effect on the molecular arrangement and on the crystal growth.

极性有机晶体在不同的溶剂中具有明显不同的生长习性，主要有两个方面的原因：一是极性有机晶体属非中心对称性晶类，晶体具有极轴，极轴的存在对分子堆积和晶体生长具有重要影响；另一是极性有机晶体的界面结构不同，溶剂与晶体界面的相互作用不同，使得晶体同一面族的生长速率不同，从而导致了晶体习性的改变。

The orthographic projection of thread will produce when the axis of thread is vertical to optical axis, which can reflect the real shape and size of thread, but the experiment and calculation show that the spiral line of thread will shield part of the teeth contour in projecting plane, and so to cause a projection with flaw.

当线的轴是垂直的时候，线的正字法发射将会生产对光学的轴，能反映真正的形状和线的大小，但是实验和计算表演线的螺旋形线将会在突出的飞机中保护牙齿等高线的部份和如此用缺点引起发射。

METHODS: Eighteen volunteers(36 eyes) aged 21 to 28 took measurements with different angles of stare, 180°, 90°, 45° from gravity axis respectively, the accommodation was measured by pushup test, and anterior chamber depth, lens thickness, axial length were measured by Aultrasonic.

体例：对18例36眼21～28岁的自愿者，取与重力轴标的目的成180°，90°，45°夹角的3个分歧凝望角度，用移近法丈量眼的调剂幅度，用眼A超丈量前房深度、晶状体厚度、眼轴长度。

The quasi linear dependence of Raman shift upon fiber strain was first used to measure the residual thermal strain along the fiber axis.Then the same dependence was used to determine the fiber strain during pull-out test.Finally the distribution of striain along the fiber axis was converted to the distribution of interfacial shear stress.

利用纤维拉曼峰波数偏移与纤维所受应变的近似线性关系，首先测定纤维热残余应变的分布，随后对伸出玻璃基体外的纤维段施加给定的拉伸应变，沿纤维轴向用拉曼光谱术逐点测定基体内外纤维的应变，最后依据力平衡原理将应变分布转换为界面剪切应力沿纤维轴向的分布。

Plunder melds and run with this jewel!

My dream is to be a crazy growing tree and extend at the edge between the city and the forest.

此刻，也许正是在通往天国的路上，我体验着这白色的晕旋。
