冶金学者

As a grain refinement technique of outside physical field, electric modification treatment is researched by a lot of physicist and metallurgist at domestic and overseas. It has an important effect on manufacturing finished products and semi-finished products. At the same time, it foreshows huge market foreground.

电变质处理作为一种外加物理场细晶技术，是国内外物理冶金学者们研究的热门课题，在材料成品及半成品的制造中起着重要的作用，并预示着巨大的市场前景。

For a decade, metallurgists studying the hulk of the Titanic have argued that the storied ocean liner went down quickly after hitting an iceberg because the ship's builder used substandard rivets that popped their heads and let tons of icy seawater rush in.

近十年来，在仔细研究泰坦尼克号的沉船遗骸后，冶金学者提出这样一个观点：这艘著名的海轮之所以在撞上冰山后迅速沉没，是因为造船者使用了质量不达标的柳钉。

Arc plasma has many advantages, such as high temperature、 high energydensity and so on. It has been applied in the field of cutting、 welding、 metallurgyand material prepared etc, but there is a long-term problem in the field of the arcplasma technology, which is how to reduce cathode erosion to increase the life-timeof arc plasma generator, so many scholars in the world have been studying theproblem on the cathode erosion.

电弧等离子体具有温度高、能量密度大和对环境污染小等特点，它已被广泛应用于切割、焊接、冶金、材料制备等领域，但是在电弧等离子体技术中，怎样减少阴极烧损提高等离子体发生器的寿命是电弧等离子体技术中一个长期问题，因而国内外的许多学者仍在对阴极烧损这个问题进行研究；本文围绕&通过提高阴极表面温度，增强阴极表面的电子发射能力，来增大阴极弧根直径，进而降低电弧通过阴极弧根传入阴极表面的有效比热流，以达到减小阴极烧损的目的。&

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。
