查询词典 perspective projection

The practical and theoretical significance of this study is concluded as the following three aspects: 1 the application of SFG's metafunction theory grasps the language patternings that encode the writer's perspective in fiction; 2 the adoption of SFG's conception of meaning potential and context facilitates the insight into the stylistic value of those foregrounded language patternings; 3 the focus of this approach on both the formal and semantic dimensions of perspective strengthens the grasp of perspective's essence and enhances the study of perspective in fiction.

本文所提出的对小说视角的系统功能语法分析模式的理论意义和实践价值在于：一，运用系统功能语法对及物性和情态的描写、分析，抓住了蕴含视角的语言样式的特征；二，采用了系统功能语法关于语义潜势和语境的理论，从而揭示了相关语言样式的文体价值；三，从语言的意义和形式相结合的层面来操作，抓住了小说视角的本质，促进了对视角在小说中的意义和价值的全面深入的探究。

In Single Point Perspective,the designer can also determinate Vanishing Point anywhere on the horizon with the need of design's expression effect.Determining Vanishing Points on the horizon in two-Point Perspective,designer draws one of Measurings with the need of design's expression effect.The another can be draw by two circular arcs in the vertical.It solute the problem easy and convenience without drawing by experience of Perspective and confirmed by memory of the Perspective Rule.

在一点透视中，确定直线长度距点也可以是设计者根据设计表达效果的需求任意确定；两点透视中确定直线长度的量点，其中一个是设计者根据表达效果的需求任意确定，另一个可以在立面图上用两段圆弧求出，方便、简单，解决了靠透视经验画图，靠记住透视规律验证的草图、效果图的问题。

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]。

Comparing the improved Taylor formula and other projection angle formulas, the improved Taylor formula correctly reflected the decreasing process of the projection angle to the final value and could describe the projection angle more accurately.

利用数值模拟得到的结果比较了平板驱动几种不同的抛射角公式，改进的泰勒公式准确反映出了抛射角下降并趋于终态的规律，其对平板抛射角的描述更为准确。

From the point on coefficient matrix of the sets of projection equations and in a broad sense axonometric projection ,the research and summarization of the development of projection theory this two centuries has been done.

从投影方程组系数矩阵及广义轴测投影分析入手，对两个多世纪以来的投影理论发展总结评述；通过数学分析，得出计算机绘图优于手工绘制轴测图的理论依据，证明计算机绘图不仅工具方便，且理论上更具有先进性

This is the defining characteristic an equidistant projection, such as the Azimuthal equidistant projection or the Equirectangular projection.

这是等距投影的核心特征，例如等距方位投影或等距圆柱投影。

According to this,the reconstruction algorithms such as Linear Back Projection,Filter Back Projection and projection rearrangement method cannot be applied directly and must be improved.

根据这一情况，在医学CT中常用的一些图像重建算法如反投影法、滤波反投影法和投影重排方法都必须加以改进才能引用。

This means that an object has a smaller projection when it is far away from the center of projection and a larger projection when it is closer.

这就意味着距离投影中心越远投影越小，距离越近投影越大。

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。

This article used the truncation mark law to discuss the common quadratic surface on the coordinate plane projection, based on this gave by the surface encircles three-dimensional asks the law on the coordinate plane projection one kind, this kind asked method the superiority lay in does not draw the range of integration graph also to be able to determine it on the coordinate plane projection.

本文利用截痕法讨论了常见二次曲面的在坐标面上的投影，在此基础上给出由曲面所围立体在坐标面上的投影的一种求法，这种求法的优越性在于不画出积分区域图形也能确定它在坐标面上的投影。最后以实例说明这种求投影的方法在计算三重积分中的应用。
