Modern geometry has multiple strong bonds with physics , exemplified by the ties between Riemannian geometry and general relativity .

自十九世纪以来发现非欧几里德几何，空间的概念，经历了一个彻底转变。

First of all,by use of the modern differential geometry and the double complex functionmethod,the definitions of dual and self-dual operators as well as ordinarycomplex Ashtekar connections are extended into parametric forms.

首先利用现代微分几何和二重复函数方法将对偶，自对偶算符的定义以及普通复阿西特卡联络推广为参数化形式。

The approximation keeps some important geometric features of the original curve such as monotonicity,convexity and G1 continuity.

逼近曲线保持了原始曲线的一些重要几何性质，如单调性，凹凸性，G1连续性。

Our simulation ofclouds and mountainous terrain was done on PC VGA Screen based on Fractal theory.

讨论了飞行模拟器上自然景象的生成与显示，并着重研究了用分形几何理论来产生山峰地貌和云彩等景象。

A new flux expansion nodal method was developed to solve three-dimensional multigroup neutron diffusion equations in hexagonal-z geometry. The method expands the intranodal homogeneous flux distributions in analytic basis functions for each energy group.

提出了一种在三维六角形几何节块内数值求解多群中子扩散方程的节块法，该方法把节块内各群中子通量分布用解析基函数近似展开。

The fractal feactures of the three dimension rock finite strain in the Xinzhou fold-thrust nappe structure have been studied in this paper.

在岩石有限应变测量和三维有限应变分析的基础上，应用分形几何理论研究三维有限应变这一复杂现象。

Geometry structure is natural and graceful, bursting out the temper of the king.

线、面、体的几何构成，雍容大气，尽显王者风范。

Results: The natural infection rate of chidren and women of child-bearing age is respectively 5.19%and 75.13%.There is no bad reaction after inoculating the nettle rash vaccine.All Children group antibody transfer to positive, while women of child-bearing age has only one negative, and GMT increase, it is a positive antibody level to propose long notably after vaccine inoculation.

结果儿童和育龄妇女的自然感染率分别为5.19%和75.13%，接种风疹疫苗后无不良反应，儿童组抗体全部转为阳性，育龄妇女仅1例为阴性，几何平均滴度增高，接种疫苗后显著提升抗体水平。

Economics is not a straightforward discipline like Newtonian mechanics or Euclidean geometry.

经济学不像牛顿力学或者欧几里德几何，它不是门直观的学科。

Nilpotent and solvable Lie groups with left-invariant Riemannian metrics play aremarkable role in Riemannian geometry.

在黎曼几何中，带有左不变黎曼度量的幂零和可解李群具有重要作用。

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。
