Results:Three important MRI feat ures of brain stem gliomas were found:①enlargement of brain stem contour.Using different sequences and planes the precise tumor location could be obtained.Sagittal scan could well display the early stage of brain stem glioma,the tectal glioma and cervicomedullary junction glioma.

结果：MRI表现有以下3个特征：①肿瘤使脑干的外形增大，通过不同序列和断面显示肿瘤的精确部位，矢状面对于显示胶质瘤的早期改变、顶盖部位及延髓颈髓联合部位的胶质瘤具有独特作用。

Contour planning with or without terracing is effective in conserving both soil and moisture.

顺等高线栽植，无论做或不做梯田对于保持水土都能有效。

Methods:50 whole brains were serially horizonatally sliced with each section 2 mm in thickness.The two -dimensional image of each section was corrected and aligned at first.After corre spondence by experts identifying thalami,tiling based on contour matching and surface-fitting with NURBS interpolation,thalami were reconstructed on computer.

对50只整脑100个丘脑作2 mm厚的连续水平切面，运用表面重建法对丘脑进行计算机三维重建；首先对各切面二维图像进行配准与校正，再采用专家辩认核团、基于轮廓匹配的轮廓拼接、非线性有理B样条插值等方法手段，精确地重建了丘脑。

Discovered by the 19th century French explorer Henri Lhote, these figures were so unusual he dubbed them Martians, explaining their contour is simple, unartistic, and with rounded heads; their only detail is the double oval at the figure's center, which evokes the image we currently have of Martians.

这些轮廓是由十九世纪的法国探险家Henri Lhote发现，是如此不寻常，他称他们为火星人，解释他们的轮廓是简单，非艺术性和拥有圆形的头，他们仅有的细节就是轮廓中央的两个椭圆形，唤起了我们当前对火星人的想象。

Bright areas reveal undeflected or stationary nodal regions while contour lines trace out areas of constant vibrational amplitude.

亮区表示未受偏转的或稳定的波节区而轮廓线则描绘出等振幅的区域。

The crucial procedure of contour detection for microscopic image of sprayed droplets and measurement of granularity is to segment droplets from background by producing binary images. The singular threshold is uneffective because the image is very different in illumination. In this paper, a fast maximum entropy image thresholding algorithm based on local gray feature is presented to exact sprayed droplets from background and preserve contours of droplets.

雾滴图像的颗粒提取与测量关键是分割出雾滴与背景，生成二值图像，由于雾滴图像光照不均匀，用单一阈值无法兼顾亮区与暗区，本文提出了一种基于局部灰度特性快速最大熵动态阈值选择算法分割出雾滴微粒并提取雾滴轮廓。

This paper introduced the concept of information entropy for analyzing the influence of DEM resolution on topographic characteristics(slope,upslope area per unit contour length and topographic index) calculation.

本文以褒河流域为例，引入信息熵的概念量化分析了 DEM分辨率对地形特征(坡度、单宽上坡集水面积和地形指数)计算的影响，发现随着 DEM分辨率的降低，计算得到的坡度值偏小，单宽上坡集水面积值偏大，从而导致地形指数计算值偏大。

The research method and principle for vadose field of confined deep water are also discussed, and the waterhead contour and hydrodynamic zoning maps are outlined for the study interval, by which flow regimes and rules of deep water are revealed in the depression.

在阐述区域地质构造和含水系统划分的基础上，论证了川西坳陷上三叠统含水系统隶属于沉积水压系统类型，提出了研究深层水渗流场的原则和方法，并根据计算勾画了研究层水头等值线图和水动力分带图，揭示了深层水的流动特点和规律

In order to dramatise the existing monuments, we suggested a strict height contour of 3 metres.

为了突出已经存在的纪念碑，我们制定了相当苛刻的限高。

The DTM for automatic-design of thruway was put forward by Prof. Miller in 1956. Since then , the DEM is used for design of various circuit diagram, and for account of area, cubage, gradient of various project, and for estimating visibility from point to point; for rendering contour, grade-graph, aspect-graph, solid model; for making orthographic image and repair map in the Topography; for assistant data to classify in the Remote Sensing; as basic data in the GIS, for analysis and layout actuality of using soil, for disaster prediction; for navigation, guiding missile in the military affairs.

美国麻省理工学院Miller教授为了高速公路的自动设计于1956年提出了数字地面模型的概念后，DEM被用于各种线路的设计及各种工程的面积、体积、坡度的计算，任意两点间可视性判断及绘制任意断面图；在测绘中被用于绘制等高线、坡度坡向图、立体透视图，制作正射影像图与地图的修测；在遥感中可作为分类的辅助数据；它是地理信息系统的基础数据，可用于土地利用现状的分析、合理规划及洪水险情预报等；在军事上可用于导航及导弹制导；在工业上可利用数字表面模型DSM或数字物体模型绘制出表面结构复杂的物体的形状[2]。
