结构用钢材

Through model test of new high- strength steel conical shell with ring frame ,and relevant analysis,it is shown in this paper that the failure of ring-framed conical shell can be traced to the neutral plane on longitudinal section where the structure strength is relatively weak.

通过新的高强度钢材环肋圆锥壳模型实验，及采用解析方法分析表明，环肋圆锥壳体破坏的原因是结构相对薄弱处纵剖面上的中面应力所致。并提出用"灰色系统"理论预测破坏载荷的计算方法，建议今后模型实验和现役潜艇的耐压船体寿命估算中可采用这种方

This seminar introduces methods for the structural analysis of historical monuments, including masonry, timber, iron, steel, and concrete structures. Short lectures will be followed by discussion sessions, together with weekly readings and a series of smaller assignments. Each student will write a final paper on a topic of their choosing. Final papers may be predominantly historical, with structural analysis to support the main arguments, or predominantly structural, with historical analysis to provide context.

概论该课程介绍了对历史丰碑上有名建筑的结构分析方法，涵盖了石材、木材、钢材、铁和混凝土结构等，课堂内以讨论的形式进行（结合每周的阅读和一系列小作业），每个学生自选主题写一篇论文作为期末论文，论文需用结构分析的方式去论证主要观点以体现显著的历史性，或者以历史分析的方式结合历史环境去表达其显著的结构特点。

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。
