Based on traditional balanced cross section in pure geometry, we put forward a method of physical balanced cross section that has two basic principles: normal direction conservation and deform matching.

作者在纯几何学方法的平衡剖面技术的基础上，着重考虑了岩石变形的物理规律，并根据岩石变形机理和物质守恒原理，提出了以法线不变原则和变形匹配原则为基础的物理平衡剖面法，实现了复杂的原始地质构造剖面的自动化恢复。

Based on the capillary pressure curve and the fractal geometry, the fractal capillary pressure and the relative permeability model are set up.

在压汞测试的基础上，利用分形几何学原理和方法，建立了毛管压力曲线分形模型和相对渗透率的分形预测模型。

Spherical trigonometry is a part of spherical geometry, mainly in the processing, discovery and interpretation of polygons on the spherical surface contact angle and the edge and relevance.

球面三角学是球面几何学的一部分，主要在处理、发现和解释多边形在球面上的角与边的联系和关联。

On the basis of geometrical research,a new method that draws sufficiently with assistant vanishing point s is provided.

通过对量点法中灭点远超出图板的难点进行分析，从几何学角度研究，在30o~60o量点法的基础上，提出一种利用辅助灭点扩大对象表现区域的新方法。

The drawing and text are sometimes called the Canon of Proportions or, less often, Proportions of Man . Leonardo based his drawing on some hints at correlations of ideal human proportions with geometry in Book III of the treatise De Architectura by the ancient Roman architect Vitruvius , thus its name.

这图和其上附言有时又被称为 Canon of Proportions ，或者偶尔也叫做《人体比例》，创作该图时，列奥纳多参照了古罗马建筑家维特鲁威的《建筑十书》的第三部书中所描述的人体黄金比例几何学，故画也因此得名。

The line that passes through the center of the Earth linking the perigee and apogee, known as the line of apsides, itself rotates in the orbital plane at a speed that depends on the geometry of the elliptical orbit and the inclination of the orbital plane to the equator.

经过地球中心，连接近地点和远地点的线称为apside线，卫星在轨道平面上以某个速度旋转，这个旋转速度根据椭圆轨道以及轨道平面到赤道的倾角的几何学来计算。

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。
