几何边界条件

On the basis of analyzing the characteristics of geological plane maps, the notion of the wire frame model illustrated by outline of geological blocks is proposed to describe the geometrical form of complex faults and the relationships among them.

在分析平面地质图数据特点的基础上，为准确表达复杂断层的空间几何形态和相互之间的关系，引入了由地质形体的轮廓线构建而成的线框架模型概念；修正了边界表示法模型有效构建的基本条件；从地层与断层之间的关系角度详细阐述了有效构建线框架模型的方法；提出了以线框架模型为基础的断层面整体构建技术思路，解决了复杂断层面三维构建问题。

Taking boundary reflection, natural degradation and background value into consideration, methods for calculating characteristic parameters of pollutant zone with outfalls randomly placed were presented, and formulas under simplified conditions were proposed.

全面探讨连续点源河流污染带的几何特徵，在考虑了两岸边界的一次反射、污染物的降解和背景值共同影响的条件下，给出排污口在任意位置的污染带特徵参数的计算方法，在简化情况下给出了直接计算公式。

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。
