起伏

The frame of 28 or 29 is formed by two-dimensional highly undulated simple layers of (6,3) topology that catenate in a parallel fashion to give, for the first time, a three-dimensional overall network, instead that a usual two-dimensional one.

首次将二维高度起伏的具有(6， 3)拓扑结构的简单层，通过一种平行方式相互铰链，广延成一种三维聚合网络结构。

In this paper, according to the characteristics of central projection, aerial photographs were analyzed to discuss displacement of images under tilt conditin or caused by ground undulation, based on which the principles of tilt error and projection error were summarized.

根据中心投影的特性，论述了像片在倾斜条件下所引起的像点位移和像片因地面起伏而引起的像点位移，在对其进行分析的基础上总结出倾斜误差和投影误差的规律，从而说明了不能把像片当作地形图使用。

In this paper, according to the characteristics of central projection, aerial photograph s were analyzed to discuss displacement of images under tilt conditin or caused by ground undulation, based on which the principles of tilt error and projection error were summarized.

本文以航空摄影测量像片为分析对象。根据中心投影的特性，论述了像片在倾斜条件下所引起的像点位移和像片因地面起伏而引起的像点位移，在对其进行分析的基础上总结出倾斜误差和投影误差的规律，从而说明了不能把像片当作地形图使用。这是使用航空像片时必须注意的基本问

On the basis of the properties of central projection and orthographic projection, the differences of different rectification approaches based on orthographic projection are explained, and it is suggested that oblique-plane-rectified photograph can produce orthographic representation of flat terrain cover; differential rectification of RS imagery based on DEM can produce orthographic representation of waved terrain cover; and true orthographic rectification based on digital ground-object model can produce orthographic representation of single objects on ground.

根据中心投影和正射投影的特点，从理论上说明了不同正射投影纠正方法之间存在的差异，认为：基于透视变换的像片倾斜纠正可生成水平地表覆被的正射投影表达；基于DEM的正射影像微分纠正可生成起伏地表覆被的正射投影表达；基于数字地物模型的真正射纠正可生成独立地物的正射投影表达。

I am drawn into the centre of the heaving mass of people and let loose.

The influence of statistical fluctuations on this method was studied with Monte Carlo simulation and CERN - NA22 and experiment data in the second part of this thesis.

在本文中，通过蒙特卡洛模拟和对 CERN - NA22 和实验数据的分析，讨论了统计起伏对这一方法的影响。

It's so up and down and challenging.

它是如此的起伏，充满了挑战。。。

He did not attempt to impart to his chasuble the folds of Elijah's mantle ,he projected no ray of future upon the dark groundswell of events

他绝不想使他的祭服具有以利亚的法衣的皱褶，他对这黑暗世界中人事的兴衰起伏，不怀任何希冀

With the chirr and murmur of insects, I lay in the grass

随虫子们的悉娑呢喃起伏，我躺在草里

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