The study of microwave-aided leaching deepens our understanding of desiliconization mechanism in leaching and presents a valuable reference for research of microwave hydrometallurgy and sulfuric acid leaching of high silica zinc oxide ores.

微波辅助浸出工艺的研究，加深了矿石浸出过程除硅机理的认识，为氧化锌矿的硫酸浸出工艺和微波湿法冶金研究提供了很有价值的参考。

The experiment confirms that the Al2O3/Cu composite material by internal oxidation of deeply aluminized pure copper matrix is a kind of superiority diathermanous copper material as being the metallurgical equipment material.

将纯铜深层渗铝内氧化A12O3/Cu复合材料的性能与纯铜深层渗铝固溶时效合金的性能进行对比，确定纯铜深层渗铝内氧化A12O3/Cu复合材料作为冶金设备用传热铜材料的性能的优越性。

Existing hydrometallurgical techniques are well understood, as is the chemistry of those techniques , but their application is to solutions that are initially relatively high in arsenic , and product specifications can be easily met.

现有的湿法冶金法技术已经很成熟，与其他化学方法一样，它们的应用是在初始浓度比较高的砷溶液，而且产物的特征能容易看到。

The results show that, there is a white zonal area between the AZ61 and Al-alloyed coating, which indicates that a good metallurgical bonding is obtained. The coating shows typical hypoeutectic structure. Due to lots of Mg17Al12 phases in Al-alloyed coating, the corrosion resistance of AZ61 magnesium alloy is increased obviously.

结果表明，涂层与基体形成了扩散白亮带，实现了较好的冶金结合；涂层具有亚共晶组织的特点；大量的Mg17Al12相存在于涂层表面是耐腐蚀性能提高的主要原因。

The results show that the composite coating is metallurgically bonded to the substrate and the microstructure is fine and uniform. The hardness of the composite coating is up to 400 HV, which is 2.5 times that of the substrate. Under room temperature and oil lubrication condition, the sliding wear tests indicate the friction coefficient and weight loss of the composite coating are smaller than those of substrate. The worn surface of the composite coatings is much smoother than that of the substrate, without grooves and crater.

结果表明，复合材料涂层与基体形成良好的冶金结合，微观组织细小、均匀；复合材料涂层硬度达400HV，约为基体的2.5倍；在室温油润滑条件下，滑动磨损试验表明复合材料涂层摩擦系数和失重均小于基体，磨损表面划痕较浅且平滑，无明显的犁沟、粘着、剥落现象；激光表面合金化显著提高了材料的耐磨性。

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。

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。
