ConclusionIn comparison with traditional rigid fixation, the lumbar "U" shape dynamic fixation system may be a better fixation instrument for the lumbar degenerative disease, which can decrease intervertebral disc stress and prevent intervertebral disc cataplasia of the adjacent segment.

结论腰椎"U"形弹性内固定与刚性内固定相比，术后能明显降低邻近节段椎间盘内应力，有利于减少和预防邻近节段退变，有望成为进行腰椎内固定较好的一种装置。

The causes of shield tunnel defections could be divided into six branches: the segment dislocations, lining material deterioration and seepage. etc. Fault trees are also founded to illustrate each branch. 23 quantitative elements from the fault trees are selected to serve as the diagnosis indexes, all of which could be applied in engineering practice. By using the AHP method, a 3-level diagnosis index system is established. Afterwards, the procedure of setting up the quantitative judging criteria is given, as well as the relative index weight of index layer, by using the improved Analytic Hierarchy Process-multiplication scale method. At last, the values of corresponding parameters of membership functions are set, with the Cauchy distribution model.

将盾构隧道常见病害成因分为管片错位、衬砌材质劣化以及渗漏水等6个子系，对每个子系构建了病害故障树；从工程应用角度出发，从故障树中选取了23个可定量化因素作为评价指标，通过层次分析法建立了三层病害评价指标体系；对体系中单一评价指标的定量化分级方法进行简述，并给出所有指标的建议分级标准，采用改进的层次分析法－乘积标度法确定了各评判指标之间的相对权重；确定了基于Cauchy分布模型的隶属函数的关键参数。

Analysing in the view of molecular kinetic theory, paste flowability is a shift of molecular mass center by the jump of polymer chain segment, and it affects the mass-transfer directly.

从分子运动角度分析，糊料流动是高聚物大分子链段协同"跳跃"而实现整个分子质量中心位移，对传质具有直接影响。

The line segment connecting the center and any point of a circle is called the radius.

连接圆心和圆上任意一点的线段叫做半径，半径一般用字母 r 表示。

A line segment that joins the center of a circle with any point on its circumference.

圆半径：将圆心与圆周上任一连接起来的线段

It is shown that the penetration rate is higher with smaller incidence angle. The central segment of the flight line is 1.6 times of the right most and left most sections, and 1.3 times penetration rate of next right and next left sections.

实验结果显示，当雷射入射角越小时，穿透率越高，反之亦然，航带中间分带穿透率约是面向航向最右五分之一及最左五分之一分带的1.6 倍，是由右方起第二个五分之一及第四个五分之一分带的1.3 倍。

The diffraction theory of Kirchhoff is applied to the four-pinhole aperture diffraction screens, the intensity, the zero-contour of the real and imaginary parts of complex amplitude and the phase distribution in deep Fresnel diffraction region are simulated, and it is found that the bright spots in interference field show central symmetry distribution. When the observation plane close to the diffraction screen, the zero-value points of light intensity can form line segment, on which the eccentricities of the light intensity isoline are close or equal to 1, the intensity changes very fast on both sides of the zero-line of light intensity.

利用基尔霍夫衍射理论计算了四圆孔径衍射屏在菲涅尔深区形成的的干涉光场的强度、零值线和相位的分布，发现干涉光场亮斑关于中心呈对称分布，在距离衍射屏较近的观察面上，光强值为的零点组成光强零值线段，该线段上光强等值线的离心率都接近或等于1，其两侧的光强值变化非常剧烈。

The results show that theheritabilities were 0.36～0.51 for body length, 0.14～0.24 for cephalothorax length,0.25～0.50 for abdominal segment length, and 0.04～0.29 for body weight.

本研究在中国对虾"黄海1号"选育研究的基础上，进行了生长和抗逆性状选育的初步研究。

Based on Bezier curve continuance of first－order and second－order derivative, the characteristic vector equation of two Bezier curve is presented in point of intersection. The algorithm is not only of high accuracy with all of the interpolated points being on the curve theoretically, but also of very high speed in the real－time interpolation processes. The interpolation velocity does not change and the segment tolerance of interpolation can be control by selecting the parameter in cerement rationally every time.

为保证两段Bezier曲线在连接点处一阶导数、二阶导数连续，导出了两段Bezier曲线特征向量应满足的关系方程，Bezier插补法不仅在理论上可使所有的插补点落在曲线上，而且实时插曲补速度高，每次插补时可合理地选择参数增量，能使插补速度保证不变，也可控制弓高误差。
