几何学上的

Through the analysis of geometrical features of Mesozoic-Cenzoic sedimentary basins in the Lower Yangtze area, we think them to be asymmetric tectonic sinked basins. They are bounded by a set of boundary fault system and failed conjugate fault, and they are segmented along axes.

通过对下扬子区中、新生代非对称性沉积盆地的几何学特征分析，认为这种非对称性构造沉降盆地在剖面上表现为由一组主边界断层和一组天折的共轭断层所围限，而且在走向上具有分段特征。

有限域上典型群的几何学及其应用

First, this paper, in the field of intrinsic geometry, studies the geometric problems on garment design, as well as applies the frame and semi-geodesic coordinates to prove the fundamental theorem of being a developable surface.

文中首先在内在几何学的层次上，研究了服装设计所涉及的几何学问题，应用标架与半测地坐标方法证明了曲面成为可展面的基本定理，研究了可展面的分类及其性质，考虑到服装三维几何造型的需要，证明了组合式可展面各组成片相切连接条件的命题，作为构造可展面的理论依据，证明了单参数平面族的包络面必为可展面的命题，在此基础上发展出服装几何造型的"刮大白"方法以及相关的三种构造可展面的解析方法。3D→2D的变换是三维服装CAD的重要内容之一，其几何学实质是曲面的定长映射，文中总结了定长映射即可展面在平面上展开的基本准则，在这一准则的指导下，结合服装设计与相关领域的要求，讨论了可展面在平面上展开的解析方法与数字方法，上述内容确立了服装设计几何学的基本框架。

From these studies I proceeded to elementary geometry, beyond which I never advanced, although I persistently attempted, in some degree, to overcome my weakness of memory by dint of retracing my steps hundreds of times, and by incessantly going over the same ground.

此后，我接着学习基础几何学，这门学科，尽管我尝试过反复地学了N多遍，并且不断从头看起，在一定程度上试图以这种努力，来克服我记忆力低下的问题，但是没有获得进展。

In field Euclidean geometry , the problem of expressing orthogonal transformation as symmetrical product is one of the basic problems in geometry .

域上欧氏几何中，把正交变换表为对称之积的问题，是几何学中基本问题之一。

Rather, we remain within the space, and carry out experiments to see whether the common laws of Euclidean geometry hold or not.

在一定程度上，我们是在空间内部，做一些实验来验证普通的欧几里德几何学是否适用。

Geometry is developed rigorously from a postulational base.

从公设的基础上严谨地推演几何学。

Geometry is developed rigor ly from a postulational base.

从公设的基础上严谨地推演几何学。

With the geometry model and kinematics model of roller cone rock bit, the interaction model of rock bit and rock is established which was based on the experiment of interaction between single tooth and rock. It is a good fundament for the computer simulation on working action of rock bit drilling.

在牙轮钻头几何学、运动学基础上，利用单齿压入与刮切岩石实验建立了钻头与岩石互作用力学模型，实现了对钻头在钻井过程中工作行为的仿真计算； 2。

And his entry for the most important competition of his life was a series of sketches of triangles and random parabolas, free shapes bounded by "curves in space geometrically undefined".

在他职业生涯最重要的那次比赛中，他的参赛作品是一连串令人目眩的形态组合图：三角形、恣肆凌乱的抛物线以及未能在空间几何学上明确定义的无数曲线，这些曲线环绕着看似信手涂鸦而来的图形。

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。
