冶金显微镜

Using carbon, iron, silicon, ferrochromium, ferrotitanium and nickel powder as the raw ma terials, chromium carbide/Fe-based composite coatings with an even and smooth surface were prepared by vacuum reactive braze coating, which combined with a mild steel substrate by a metallurgical bonding.

以纯铁粉、硅粉、硼铁粉、铬铁粉、胶体石墨及镍粉为原料，通过真空反应钎涂在低碳钢基体上制备了碳化铬／铁基自熔合金复合涂层，涂层表面光滑、平整且与基体为冶金结合。应用扫描电子显微镜、能谱仪、X射线衍射仪及显微硬度计，研究了涂层的组织结构、成分分布和硬度分布。

On electrical properties of multicrystalline silicon prepared by metallurgic method was investigated.

利用四探针电阻测试仪、光学显微镜、扫描电镜、电感耦合等离子发射光谱仪、能谱分析等设备，从晶粒尺寸、组织形态以及晶界析出物等对冶金法制备的多晶硅电阻率的影响。

Recent years, with the development of optical technology, the Polarizing microscope is in widely use.

N-501P偏光显微镜 N-501P 透射偏光显微镜是地质、矿产、冶金等部门和相关高等院校最常用的专业实验仪器之一，近年来，随着光学技术的不断进步，作为光学仪器的偏光显微镜，其应用也越来越广泛。

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。
