转换点

Based on these theories, it develops a GIS map projection software using Visual C++ as a platform. The software consists of two parts: analytical ordinal transformation and analytical athwart transformation. Analytical athwart transformation implements map projective transformation with coefficients obtained through numerical method, which is also the main idea of this paper. Map projective transformation process is illustrated with the examples of Mercator projection and conic projection.

地图投影建立了平面上的点(用平面直角坐标或者极坐标表示)和地球表面上的点之间的函数关系，而地理信息系统以平面直角坐标形式通过计算机图形学的方法表示2维或3维地理空间信息，因此，地图投影起到了地球空间与地理信息系统之间的坐标转换的桥梁作用[1]。

The television camera also looks at a scene as a series of dots; each dot of light is translated by the camera tube into an electronic signal.

电视摄像机同样把图像看成一系列的光点，每个光点都由摄像管转换成电子信号。

According to the limited space the end of all surface sampling points in 3D space within the Cartesian coordinates, then be converted into computer on the screen coordinates of the pixel, thus drawn with a real sense of three-dimensional images.

根据有限空间中底面上所有采样点在三维笛卡儿空间内的坐标，然后将其转换为计算机屏幕上的像素点的坐标，从而绘制出具有真实立体感的图像。

The extracted P-wave is reverse-time extrapolated and imaged with a P-velocity model using a finite difference solution of the scalar wave equation, the extracted S-wave is reverse-time extrapolated and imaged similarly, but with an S-velocity model, and converted S-wave data requires a polarity correction prior to migration to ensure constructive interference between data from adjacent source.

在模型中，每个网格点的纵、横波成像时间，为震源到该网格点的纵波初至时间。利用纵波速度模型和声波传播方程的有限差分解，对反射纵波进行逆时延拓和成像，利用横波速度模型和声波传播方程的有限差分解，对转换横波进行逆时延拓和成像，并在偏移前进行极性校正。

At last, transformed the points on the outline of abrasion zone into coordinate through CF function, which included all the information in the zone.

最后通过CF函数，将图像上磨损区域轮廓上的点转换成坐标点，其点准确涵盖磨损区域的信息。

Finally, based on the homonymous points, this paper has taken the indirect adjustment with conditions method to resolve the model and the analysis on errors is carried out. The results show that the two selecting method both meet the requirements of the accuracy of data modeling.

最后，根据选取的同名点，本文采取了附有条件的间接平差对转换模型进行解算，并进行了误差分析；实验证明两种提取同名点进行数据拼接的方法都可以满足数据建模的精度要求。

I have been converted to the concepts you have in the report in particular those of Napoleon Hill you wrote abut with people being wishers or hoper 's instead of believers , which I have expressed in an early blog on this site when answering a point on the law of attraction for Pat .

我已经转换为概念，你在报告中，尤其是那些在拿破仑希尔，你写邻接与人的祝福或 hoper 的不是信教的，这点我已表示，在此前博客关于这个站点时，在回答点上吸引定律为八。

Then, the boundary points are extracted. By using Shu's theorems the sum of Legendre polynomial of the boundary points is calculated.

首先使用Yang-离散格林公式将二值图像矩计算中区域内求和转换为沿区域边界求和；然后提取该图像的边界点；再利用Shu提出的公式计算出边界点的Legendre多项式的叠加值。

In SPVT (security protocol verifying tool), the specification language is the π-like calculus extended with three appendixes, the Dolev-Yao model is described with Horn logic rules, the π-like calculus model of security protocol is transformed into the logic program model by abstract rules, the security properties are verified based on the calculus of the logic program's fixpoint, and the counter-examples on security properties are constructed from the process of the fixpoint calculus and the process of the property verification.

在SPVT中，以扩展附加项的类演算作为安全协议描述语言，以扩展附加项的Horn逻辑规则描述协议攻击者的Dolev-Yao模型，通过一组抽象规则将安全协议的类(演算模型转换为逻辑程序模型，基于安全协议逻辑程序的不动点计算验证安全性质，从安全协议逻辑程序的不动点计算和安全性质的验证过程中构造不满足安全性质的安全协议反例。

Optical fiber communication is transferring form point-to-point transmission to mesh network. Traditional optical-electronical-optical transformation limits the data rate and adds the cost. With reconfigurable optical add/drop multiplexer for signal switching and routing, the OEO transformation can be bypassed, reduceing equipment size and cost.

光纤通信由点到点传输向网格化发展，传统的光—电—光转换过程限制了通信速率并导致成本增加，采用可重构光分叉复用器进行光交换和光路由，可以省去光—电—光转换过程，缩小尺寸和降低成本。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
