Results showed that total vegetation coverage, herbaceous coverage, and species richness were all decreased, and perennial species gradually gave place to psammophyte annuals, shrubs, and semi-shrubs from gentle slope hilly ridge, through saline bottomland and fixed and semi-fixed dune, and to shifting and semi-shifting dune.

结果表明，从缓坡丘陵梁地，经盐化丘间低地、固定半固定沙地到流动半流动沙丘，植被总盖度、草本植物盖度、物种丰富度均呈下降趋势；植被组成中多年生草本植物逐渐减少，一年生草本植物及沙生灌木、半灌木逐渐增加。

Firstly, the high resolution pictures of dragonfly wings from sample tests were studied thoroughly, and the unique feature of the reticulate vein distribution and the variation of the vein sizes and the grid shapes in different zones were figured out;then several computational models based on a dragonfly wing were established by using ANSYS, and beam 189 and shell 93 elements were used respectively in modeling of the veins and the membrane so as to ensure the compatibility between the veins and the membrane at a deformed state;these models subject to uniform loading cases were analyzed respectively so as to explore the unique performances of the wing structure, furthermore, through eigenvalue spectrum analyses of these models, the special role of the pterostigma in eliminating or suppressing the wing quivering effect was also evaluated.

首先，对实验中获取的高清晰度的蜻蜓翅膀数码图片进行了细致地分析，找出了翅膀网状翅脉结构中翅脉的分布规律与尺寸变化、网格形状的差异及不同形状网格的分布等独特的结构特征；再利用ANSYS建立蜻蜒翅膀网状翅脉结构模型，采用三节点等参数梁元beam189模拟翅脉和八节点等参数曲壳单元shell93模拟翅膜，以满足翅脉和翅膜间的变形协调性要求；通过非线性数值分析，探索了蜻蜓翅膀网状翅脉结构在均布荷载作用下所具有的独特的结构性能；通过模态分析，揭示了翅膀前缘靠近翼尖附近的翅痣在翅膀消震减振中所发挥的作用。

Along with the popularization and application of separative box-girder, people already not solely requested the structure analysis to be able to reflect the actual situation, hoped could obtain the satisfactory result quickly and economically.

随着分体箱梁结构在桥梁工程中的普及应用，人们已经不单单要求结构分析能够反映实际情况，更希望能快捷、经济地获得满意结果。

The traction arm includes: a first supporting plate slidably connected to a beam of the bench; a second supporting plate pivotally connected to the first plate for the rotation of the base about a first axis that is substantially horizontal and substantiallty at right angles to the front plane of the first plate for appllying the base to the repair bench; a third supporting plate pivotally connected to the second plate for the rotation of the base about a second axis that is substantially at right angles to the first axis; and pivoting elements for the rotation of the base about a third axis that is substantially at right angles to the second axis.

牵引杆包括：一可滑动地连接于修理台梁的第一支承板；一枢接于第一板、用于使底座绕一大体上水平且大体上垂直于将底座装在修理台的第一板的前平面的第一轴线而转动的第二支承板；一枢接于第二板、用于使底座能绕一大体上垂直于第一轴线的第二轴线转动的第三支承板；以及用于使底座能绕一大体上垂直于第二轴线的第三轴线转动的枢接件。

At last, the paper discusses distortion detection methods of Magnetically Suspension Train project. With VisualBasic6.0, we opens out naturalization layout and precision assessing software which can compute layout data and assess precision well and truly to guide construction layout conveniently. Thus, the efficiency of work can be heightened. Opening out distortion inspect and analyze software, can ascertain base's settlement, peg tip' distortion and the movement of tramroad girder's plane position in course of construction and using. This can provide bases to later alike projects.

本文在VisualBasic6.0环境中开发的磁悬浮工程归化法放样与精度评定系统软件，在施工放样阶段能比较方便、直观、准确地计算出放样数据并进行精度评定，以指导现场施工放样工作，可以大大地提高工作效率；开发的变形监测与分析系统软件，可以在施工过程中以及工程运营期间对整个工程进行变形监测处理，用以确定基础沉降和桩顶变形以及轨道梁平面位置的变化，从而可以为以后的同类工程建设提供依据。

The statue was placed as the prince ordered, and promptly forgotten by the world, but every morning, and every noon, and every evening the prince stole quietly away to where it stood and looked long upon it, noting the straight back and the unlifted head, and the noble brow.

于是按照国王的命令，雕像被立在了后花园里，而且很快地被世人所遗忘。但是每个清晨、每个晌午、每个夜晚国王都会悄悄的过去注视这副雕像。别的都不看，就光注意着那直直的背梁、微微向下的脑袋和高贵的表情。

So, how to identify the damage in beams effectively has become a very important research subject.

如何有效地识别梁内损伤已成为一项重要的研究课题。
