几何的

The same could be said for any and all intersecting geometry.

同样可以说任何及所有相交的几何形状。

The number of intersection points of l : ax + by + c = 0 and the centroid curve L :{(x|ˉ,| h ∈∑} gives the number of zeros of I.

在第四章中，考虑到系统在二次多项式扰动下的几何意义：若I=∫ integral from n=intrdxdy，那么直线l：ax+by+c=0与质心曲线L∶{

First-principles plane-wave pseudopotential calculations were performed to study energetics , the geometry structures of intrinsic vacancies and interstitials on the anatase TiO2 (101) crystal surface.

采用平面波超软赝势方法计算了锐钛矿型TiO2(101)面存在本征空位和间隙点缺陷的几何结构以及缺陷形成能。

Secondly, the concept of column space, cyclic invariant subspace and generalized cyclic invariant subspace were introduced.And some basic properties, such as separation lemma, were presented.

其次，引入列空间、循环不变子空间和广义循环不变子空间等基本几何概念，给出一些有关概念的基本性质，特别是分离引理。

A gesture recognition algorithm based on two features of invariant moment and edge detection is presented.

提出了一种结合几何矩和边缘检测的手势识别算法。

There is also something called an ionic bond, which is a type of chemical bond in which positively charged ions are electrically attracted to negatively charges ions.

它们是相互吸引而形成几何排列的离子。

In this paper, the measurement method and system for rail track geometric irregularities is studied based on this problem.

本文为了满足这一要求，对线路几何不平顺的高精度测量方法和系统进行了研究。

A sufficient and necessary condition of an isothermal surface being a minimal surface is obtained.

除平面外没有其它二次多项式极小曲面，Enneper曲面是目前微分几何文献中唯一出现的三次参数多项式极小曲面，还没有出现高次多项式极小曲面的例子。

Based on vector plots analysis, this paper researches the geometric frame of iterative learning control method.

基于向量图分析，对迭代学习控制方法的几何框架进行探索。

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。
