There are now 2000 years of historical heritage sites, the desert oasis of natural landscape and the composition of the modern human landscape.

主要有距今二千多年的历史文物遗址，沙漠绿洲自然景观和现代人文景观组成。

For example, the roll elastic deformation breaks the statically determinate condition of roll system in duo mill, and this is the main reason of bearing longevity shortening and burning accident; in aluminium foil four-high mill roll system with a 1 mm gap, the ideal position kept by a 3 mm offset is out of effect, some phenomenon such as chock horizontal vibration, gyroscopic effect and micro dimensional dynamic cross happen in fact rolling process, abnormal super and partial load resulted by these is the main reason of the end thrust bearing accident; the thermal deformation of mill roll system accompanying the temperature raising not only changes the roller track age of rolling bearing, but also results a micro dimensional slow dynamic inverse cross that counteracts the gyroscopic effect in a degree.

如二辊高刚度轧机轧辊的弹性弯曲微尺度行为，破坏了辊系机构杆系的静定条件，成为轧机轴承短寿烧损的主要根源；铝箔四辊轧机只具有1mm的有隙辊系，凭借设置3mm偏移距和轧制力平衡产生的水平力以保持轧辊理想定位失去效用，却发生轴承座水平振动现象、陀螺效应和动态交叉微尺度行为，成为止推滚动轴承异常超偏载导致短寿烧损的主要根源；轧机辊系的伴随升温产生的热变形，不仅改变了滚动轴承滚道轮廓，还引起运动副内慢变动态反交叉微尺度行为，抵消陀螺效应的部分动态交叉角度。

Based on that,the problem of reconstruction is studied according whether the axis-track surface is developable or not,and some valuable conclusions are derived.

在得出包络面、轴迹曲面、等效轴迹曲面互为等距曲面的结论的基础上，研究了轴迹曲面可展与不可展两种情况下的非等径包络重构问题，得到了一些有价值的结论。

As an example, we designed a new double telecentricity projection lens with NA=0.42, magnification M=-1/5, field size 15 mm×15 mm (21.2 mm diametre) and conjugate distance 602 mm.

设计了一种新的双远心投影物镜，其数值孔径NA=0.42，放大倍率M=-1/5，像场尺寸15 mm×15 mm(直径21.2 mm)，共轭距L=602 mm。

Based on the Sum of Eight Adjacent Points Square Difference Operator and Varying Step Search Arithmetic, A set of autofucos system has been designed and realized in this thesis.

在自动测量系统的开发过程中，提出了叛定图像清晰度的八邻点平方差之和算子与变步距遍历搜索算法，在实际应用中达到了较好的效果。

Since we adopt Newton interpolation of difference quotient from the discrete data pool of unequal distance node among the scaled temperature (20℃, 1000℃), aluminum purity and aluminum density, it can greatly be approached.

我们从刻画的温度( 2 0℃、1 0 0 0℃)、铝纯度与铝密度间不等距结点的离散数据集中、采用了Newton差商插值、能极好地加以逼近、从而建立了高精度的四阶非线性数学表达式、由此从该模型中给出了 2 0℃时的高纯度铝( 99 999%～ 99.99999%)的密度值，其结果令人满意。

The result reveals that the diameter of incident spot is very important to the sensor's resolving power for the diffraction pattern of VLS grating.

结果表明：基于变栅距光栅的衍射特点，入射光斑直径的大小是影响传感器分辨率的一个重要因素。

They approximate the appearance of the real object through axonometric(isometric, dimetric, and trimetric) representations.

他们近似的外观实物通过轴测（等距， dimetric ，并trimetric ）申述。

Elastic anisotropy means that velocity depends on the direction of propagation, this angular dependence of velocity is expected to influence reflectivity changes with offset.

弹性各向异性意味着弹性波传播速度与传播方向有关，这种速度对入射角的依赖性必然会影响反射振幅随偏移距的变化。

With a 15-minute dirve to the world expo hall only,canbridge enjoys an advantageous location geographically.besides, cambridge industry park was listed as the municipal-level industry district of shanghai in 1994 and enjous preferential policy of p_udong new area with unique advantages in business promotions.as people always say, inthe north there is jinbridge and in the south there is cambridge.with the adjacent xhongqiao college and jianqiao college as a scientific support and advantageous location and policy adbantages of the cambridge industry park,we warmly welcome business people from all walks of life to make investment in the cambridge industry park and settle in our company.

And Pharaoh spoke to Joseph, saying, Your father and your brothers have come to you.

47：5 法老对约瑟说，你父亲和你弟兄们到你这里来了。

Additionally, the approximate flattening of surface strip using lines linking midpoints on perpendicular lines between geodesic curves and the unconditional extreme value method are discussed.

提出了用测地线方程、曲面上两点间短程线来计算膜结构曲面测地线的方法，同时，采用测地线间垂线的中点连线和用无约束极值法进行空间条状曲面近似展开的分析。
