冶金学

Coming to the fifties of the 20th century, metallography developed successively into physical metallurgy and materials science

到了二十世纪中叶，金相学已逐步发展成金属学、物理冶金和材料科学。

During the production scheduling, the metallurgist would fully utilize metallurgical transaction controlled rolling, precipitation, etc.

在制定生产规程时冶金师将充分利用金属学转变，以产生首选的组织结构和尽可能好的成品性能。

Besides , some unfathomed problems about application of stereology and image measurement in industry have been raised .

体视学，图象检测技术在冶金工业中的应用及进展

Tight alloying layer with undulation and without visual pocket and inclusion has been obtained by experiment.The alloying layer is metallurgically combined with the matrix.

试验结果获得了致密、无肉眼可见气孔、夹杂、熔覆表面有一定起伏的合金层，合金层与基体间完全冶金结合；熔覆合金层由单相Fe3 Al构成，覆层组织为粗大的柱状晶团，柱状晶团内包含大量极细小的板条状Fe3 Al晶粒，一些相邻的板条晶之间具有基本相同的晶体学取向。

Dense alloy coating without pore and inclusion is obtained which metallurgically bonded with steel but existing a few cracks. The results show that the cladding alloy coating is mainly composed of single-phase Fe3Al, and the microstructure is coarse equiaxed grain-groups that consist of large amount of fined slug like Fe3Al grains, between which some adjacent grains have the similar orientation.

试验获得了致密、无肉眼可见气孔、夹杂的合金层，合金层与基体间完全冶金结合，但存在裂纹现象；熔覆合金层主要由单相Fe3Al构成，覆层组织为粗大等轴状晶团，等轴状晶团由大量极细小的条状Fe3Al晶粒构成，一些相邻的条状晶粒之间具有基本一致的晶体学取向。

Recently, the advocates of "breaking in" harmonicas have claimed that the procedure is akin to a metallurgical process called "coaxing".

最近，有&开琴&的鼓吹者声称此过程类似于冶金学的的&coaxing&处理，但是权威资料显示并非如此

The effect of austempering on the wear resistance of austempered ductile iron was studied.

等温淬火球墨铸铁(Austempered Ductile Iron，简称ADI)是近30年来铸铁冶金学方面的重大成就之一[1]。

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。
