平面几何

It thinks that Complete Principle of Measurement inherited the Writing Style of Elements. Secondly, it is taken out five key parts——plane geometry, solid geometry, conic, spherical trigonometry and spherical astronomy part——to comprehend. The main contents of mathematics and astronomy involved in Complete Principle of Measurement have been set up respectively in accordance with the characteristics of their subject.

其次，又按照学科分布从中抽出平面几何、立体几何、圆锥曲线、球面三角和球面天文等五部分内容进行重点解读，认为《测量全义》中所涉及到的主要数学和天文学内容已经按照学科特点分别形成和建立起来，为后来西学的进一步传播做出了贡献。

Therefore in the teaching students should be made to actuallyfeel that spherical geometry knowledge can be used to solve or explainsome real problems in both life and production, to reach the relatedconclusions about spherical geometry by comparing it with Euclideangeometry, and to have anidea of some non-Euclidean geometry models aswell as differences between flat geomtry models and spherical geometry ones.

是为对数学有兴趣和希望进一步提高数学素养的学生而设置，重点是培养学生空间想像和几何直观能力，教学中应使学生切实地感受到利用球面上的几何知识可以解决生活或生产中的一些实际问题；让学生通过欧氏几何和球面几何的类比，得到球面上的几何的相关结论；使学生了解一些非欧几何模型，从而思考平面几何模型与球面上的几何等非欧几何模型的差异。

A planar geometric spline, biarc spline, is generalized to a 3D geometric spline whose curvature and torsion are all constant.

给出基于非线性规划解的双圆柱螺线样条局部构造法，把平面几何样条——双圆弧样条推广到常曲率和常挠率的空间几何样条。

Based on the analysis on the transformation model of anterior-posterior and lateral projection spaces, initial registration parameters are automatically estimated and the mapping from the 3D surgical space to the CT space is established by using the biplanar geometric constraint.

通过分析正侧位投影空间变换模型，利用该双平面几何约束实现自动的配准初值估计并建立3维手术空间与CT空间的映射。

Dan Kiley has for a long time designed on the basis of a formal organization of his landscape, classic in the sense that its foundations include the traditions of both Islam and the West. His are ordered landscapes, normally with a clear geometric plan structure which nevertheless reads excitingly in three dimensions.

丹凯立长期以来都以形式组构为基础进行地景设计，呈现出伊斯兰与西方传统所具有的古典感；他的作品是秩序性的地景，通常有清楚的平面几何架构，然而在三向度中却又十分引人。

This article first explains the content and the theoretical basis of the Geometers Sketchpad and the integration of geometry teaching, and then analyzed the feasibility and the advantages of the Geometers Sketchpad integrating with teaching, and then put forward what principles and measures should be noted in the integration of teaching, and finally gave some specific cases.

本文首先针对几何画板与平面几何整合教学的内涵和理论基础进行分析，接着分析了几何画板整合教学的可行性及其优势，然后针对整合教学提出应注意的原则及措施，最后对整合教学给出了具体案例。

Questions in this content area are based on the properties and relations of plane figures, including angles and relations among perpendicular and parallel lines; properties of circles, triangles, rectangles, parallelograms, and trapezoids; transformation; the concept of proof and proof techniques; volume; and applications of geometry to three dimensions.

平面几何（23％）。这方面的考试内容是基于平面图形的性质及关系，包括角度，垂直线和平行线之间的关系；圆，三角形，矩形，平行四边形和梯形的特性；图形的转化；几何证明的概念和证明的技巧；体积以及几何在三维的应用。

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

在对危险的南部地区访问时，他斥责什叶派民兵领导人对中央集权的挑衅行为。

In fact,I've got him on the satellite mobile right now.
