In this study, a finite element method is used to develop a numerical model for the simulation of combined wave refraction, diffraction, reflection, shoaling and breaking in the nearshore zone.

中文摘要本计画拟利用有限元素方法，建立近岸波场模式，模拟波浪以大角度入射近岸地区时，波浪因地形、人工结构影响产生之折射、绕射、反射、浅化及碎波等波浪之变形。

Beijing's roads are built in the Ming Dynasty, because the Ming Dynasty骑射poor people, in order to prevent军攻Mongolia has run into the city after, obviously narrow urban road, and alley entrance dislocation for infantry street fighting, so that Beijing's roads are in accordance with the Sedan Chair son of street fighting infantry designed from the Sedan Chair son walk to the car traffic, the "generation gap" can be imagined.

北京市的道路是明代修建的，因为明朝人不善骑射，为了防止蒙古军攻入城后长驱直入，城市道路明显偏窄，且胡同口错位，便于步兵巷战，因此，北京的道路是按照抬轿子、步兵巷战设计的，从抬轿子、步行到汽车交通，这个&代沟&可想而知。

In order to obtain a correct height distribution of a measured object using the conventional Fourier transform profilometry, the connecting line between the exit pupil of the projecting system and entrance pupil of the imaging device must parallel to the reference plane and in the same horizontal.

在传统傅里叶变换轮廓术三维面型测量中，为了准确得到被测物体的高度分布，必需保证投影仪出射光瞳和摄像机入射光瞳的连线与参考面平行并且在同一水平面，否则存在较大的误差。

In order to obtain the correct height reconstruction of a measured object through the traditional Fourier transform profilometry, the connecting-line between the exit pupil of the projecting lens and the entrance pupil of the imaging lens must be horizontal and set to parallel to the reference plane.

在拍摄过程中，采集完参考平面的光场后，只需要再采集一帧条纹图形，通过傅里叶变换、频谱滤波、逆傅里叶变换、相位展开等处理后就能得到物体的三维数据。采用传统的傅里叶变换轮廓术进行三维物体面型测量时，必需保证投影装置出射光瞳和成像装置入射光瞳的连线与参考面平行，并且它们的光轴应在同一平面上，才能得到较为准确的测量结果。

A polycapillary X-ray lens with spot size of 41.7 μm was applied to focus original X-ray and a slit of 50 μm was located in front of the detector to improve angle resolusion.

为了提高入射X射线的强度并提高系统的空间分辨率，选用焦斑为41.7 μm的会聚透镜对原级X射线进行会聚，并在探测器前加上50 μm的狭缝以提高掠出射角扫描的角度分辨率。

It can be surely concluded that in generalcases the matrix characterising the action of the optical system can be truncatedto finite order within any given errors….

The intensity of laser signal incident straightly on the surface of photoelectric detector of the warning apparatus was calculated under different atmospheric visibilities in this paper. Both the target reflection and the atmospheric dispersion were considered also. The sensitivity of the vehicular laser warning device was discussed to provide a guideline for the development and design of the device.

分析计算了激光在大气传输中在不同能见度下直接入射到告警接收机光电探测器表面上的信号辐射度，以及目标溅射和大气散射情形下的激光信号辐射度，对车载激光告警器灵敏度指标的确定进行了论证，为系统设计和研制提供了依据。

Neither the killing of Mr Zarqawi nor any breakthrough on the political front will stop the insurgency and the fratricidal murders in their tracks.
