主要观察指标：椎弓根螺钉在轴向压缩、前屈、后伸、侧屈和旋转等各种生理载荷下的应力云图和峰值。

Based on the study in Lotus japonicus, a model legume plant in Papilionoideae, scientific groups led by Luo Da demonstrated that TCP proteins have been independently recruited as determinants of petal identities along the dorsoventral axis in two distant lineages of flowering plants Antirrhinum majus and Lotus japonicus, suggesting a synapomorphic origin for the mechanisms in the control of floral zygomorphy.

以蝶型花亚科的百脉根为研究对象，罗达等研究组阐明了在豆科与其他物种基因组中调控花对称性发育的分子机制具有共源性，揭示了在高等植物花形进化过程中，不同进化关系的开花植物独立地招募TCP基因，调控了两侧对称花发育过程中背腹轴的发育。

This paper reviews whether forward movement of the posterior corneal surface occurred, changes in posterior corneal power and curvature, changes in posterior corneal astigmatism and tilt, changes in posterior corneal asphericity and BFS after the surgery.

本文综述了准分子激光屈光性手术后角膜后表面是否发生前移改变、角膜后表面屈光力、曲率、散光度、轴度、非球面特性以及最适球面等是否发生改变的研究进展。

MRI with various sequences has higher diagnosis value in acute cerebral trauma diagnosis,and can make up CT in insufficient diagnosis to the cerebellum,the brain stem,temporal lobe edge contusion and axis cylinder injury,which is worthy of further clinical study and application.

MRI各序列在急性颅脑损伤诊断中具有较高的诊断价值，可弥补CT对小脑、脑干、颞叶边缘挫裂伤及轴索损伤等诊断的不足，值得临床进一步研究和应用。

Because there is a box-hole processing machine tool, gear and other processing error, the tool axis of rotation of the drive space is too large, large amount of so-called open.

因为有一个盒子，孔加工机床，齿轮等加工误差，驱动器的空间旋转刀轴过大，大量的所谓公开的金额。

If the shaft seal bad back, there will be large number of resin powder leaked, each class should be pressed for several Pan-gen still leakage phenomenon not only affects the sanitation, and increase the volume of maintenance and therefore a need to use The system forms a seal 4 gear is reasonable Screw conveyor is the use of motor driven rotary screw, the passage of materials in order to achieve the purpose of transportation machinery, it can level, tilt or vertical transmission, a simple structure, small cross sectional area, sealing, and easy to operate, easy maintenance, facilitate closure transportation and other advantages.

如果轴后端密封不好，就会有大量树脂粉泄漏，每个班要压好几次盘根，仍有泄漏现象，既影响了环境卫生，又增加了维修量，因此急需选用一种适用于该系统的密封形式 4传动装置的合理性螺旋输送机是利用电机带动螺旋回转，推移物料以实现输送目的的机械，它能水平、倾斜或垂直输送，具有结构简单、横截面积小、密封性好、操作方便、维修容易、便于封闭运输等优点。

It consists mainly of seat plate, right and left side main magnets, double-layer repelling cavity comprising upper and lower magnets, front and back bending magnets, turntable shaft, turntable, magnetic bars and power output wheel.

它主要是由坐板，右、左侧板式主磁体，双层全排斥腔上、下部磁体及前后面折向磁体，转盘轴，转盘，多根条磁体，动力输出轮等组成。

The results indicate that the discontinuous surface such as weak interlayer, bedding plane and joints are the major factors which control the deformation of the rock mass, the existence of weak interlayer influenced the distribution of shear displacement, stress and plastic zones, which is also a major factor result the axial forces increased rapidly during construction.

结果表明，结构面（如软弱夹层、层面和节理裂隙等）是控制图岩变形的主要因素，软弱夹层的存在控制了围岩剪位移、应力和塑性区的分布，是导致锚杆轴力增大的主要因素，实时监测资料和理论计算成果吻合良好。

This dissertation discusses the anisotropic behavior of soft clay and its effect on the deformation of excavations based on the study of other researchers. The main achievements of this thesis are as follows: 1 Firstly, an anisotropic bounding surface constitutive model(Wei, 2005) is recommended, secondly, the deformation of triaxial compression tests and triaxial extension tests under condition of isotropic consolidation is analyzed qualitatively.

基于此，本文在前人研究的基础上，探讨了土体的初始各向异性以及应力诱发各向异性对基坑开挖变形的影响，取得了如下研究成果： 1、利用魏星(2005)提出的各向异性弹塑性本构模型，分析了具有初始各向异性土样在等向固结三轴压缩和拉伸试验中的变形特性。

The main problems of pumps in hydraulic characteristics such as low pump efficiency, humble head-flow curve and easily overload brake horsepower etc, and their countermeasures developed in recent years including greater flow design and non-overload theory etc, are introduced thoroughly.

介绍了低比转速离心泵水力设计和结构设计研究现状，分析了低比转速离心泵水力性能方面存在的效率较低、扬程曲线易出现驼峰和轴功率易过载等问题产生的原因及解决办法，对各水力设计方法进行了评述。

I am accused of being overreligious," she said in her quiet, frank manner,"but that does not prevent me thinking the children very cruel who obstinately commit such suicide.""

客人们在卡罗利娜·埃凯家里，举止就文雅一些，因为卡罗利娜的母亲治家很严厉。
