The coatings formed on Q235 steel possess microcrystalline structure, with a thickness about 100 m. The micro-crystal line structure is achieved due to the high cooling rate during deposition. The quality of the coatings is enhanced by using Ar to protect samples from oxidation. The coatings are metallurgically bonded to the substrate without obvious interface.

采用振动式电脉冲沉积技术沉积涂层时，铝电极与工件瞬时接触放电，可以达到很高的温度，从而形成了铁铝金属间化合物涂层，而且涂层与基体为冶金结合；涂层冷却速度很快，由此获得微晶结构涂层；流动的氩气可有效地保护涂层的质量。

The phase structure of the ceramic-coating includes γ-Al2O3, AlPO4 and CoO. The forming process of the ceramic-coating includes iron movement, melting of surface layer, movement of electrolyte towards the melting-zone and the final nucleus-forming and sintering. The ceramic coating looks like islands and islets. The ceramic coating and the matrix are integrated metallurgically.

结果表明：该陶瓷膜层由γ-Al2O3， AlPO4和CoO等组成；通过对陶瓷膜层的表面形貌和显微结构观察及分析，发现陶瓷膜层形成过程是一个离子运动，表面层不断被击穿形成熔融区，处理体系中的电解质不断向熔融区运动、成核并迅速烧结的过程；陶瓷膜层呈现岛屿状；陶瓷膜层与基体之间为冶金结合。

Results show that at 500℃ polycarbsilanedecomposed into noncrystallized SiC and free caron and impurities which hinder the densificationof the composite are also found during the above decomposition process, with the increase ofheating temperature, the noncrystallized SiC can be transformed into β-SiC.

一般传统的制备方法是，向C和SIC粉末中添加烧结助剂B，B；，A12O；；AIN等球磨混合，采用粉末冶金热压烧结；尽管采取了一些特殊的工艺手段和添加烧结助剂的方法，但该材料须在高于2000t时烧结且致密化效果较差［'1。

It is not only the raw material for producing semiconductor - class polycrystalline silicon and optical fiber preform , but also the important raw material for organosilicon industry and metallurgical industry .

它不仅是生产半导体级多晶硅和光纤预制棒的原料，而且是有机硅产业的重要原料，同时也是冶金工业的重要原料。

The spring-wires main problems are poor qualities,low-grade mechanical property and unattained requirement of surface property.

本文综述了目前应用的弹簧钢丝的生产工艺及组织性能特点，指出冶金质量差，力学性能低和表面质量达不到要求是目前弹簧钢丝存在的主要问题。

The structure of the implanted zone and unimplanted zone was observed by X-ray photoelectron spectroscopy and high voltage electron microscopy.

结果表明：复合渗镀＋PVD法沉积的TiN薄膜呈较为均匀、致密、细小的组织，Ti和N原子由表层呈梯度向内分布。与PVD法沉积的TiN层不同，是属于冶金扩散结合层，渗镀层厚度可达10μm以上。

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. More than 1,500 people died.

冶金学家花了十年时间仔细研究了泰坦尼克沉船的船体，提出这样一个观点：这艘深海巨轮在撞冰后迅速沉没是和造船厂使用了不合格铆钉分不开的，铆钉头的崩落使得冰冷海水瞬时涌入以至逾1500人罹难。

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。

In this paper,the discussion is emphasized on the following process flowsheets in Chinese nickel metallurgy,such as the current smelting of low nickel matte with electric furnace and flash furnace concerting of high nickel matte with concterer separation of nickel from copper in grinding and flotation process anode electrolyting of nickel sulphide;two stage counter current ...

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。
