The process of three-step countercurrentleaching is presented, in the first leaching step Fe as leading impurity inthe matte is leached priorly, Co and Ni are enriched in the residue of thefirst step and then are leached in the second leaching step with a lowconcentration acid, the residue from the second step containing hardleaching Fe, Co and Ni are leached with a high concentration sulfuricacid in the third step, and Cu stays in the final resude, the leachate of thethird leaching step is diluted and divided into two parts as the leachantsto the first and second leaching step.

在此基础上，提出了三段逆流选择性浸出技术：即第一段用低酸优先浸出钴冰铜中杂质铁，将钴镍富集到第一段的浸出渣中，第二段再用低酸浸出渣中部分钴镍，第三段用高酸浸出第二段渣中难浸的钴镍铁，将铜留在最终的浸出渣中，第三段浸出液经稀释，分流，分别返回至第一段，第二段作低酸浸出介质。

The optimal technical conditions of the later were that cuprous chloride and 1,10-phenanthroline were used as catalyzer, the molar proportion of catalyzer and 4,4′-diiodobiphenyl was 0.15:1, and the reaction mixture was refluxed for 7h in the solvent of xylene at 150℃.

后者的适宜工艺条件为以二甲苯作溶剂，氯化亚铜和邻菲咯啉为催化剂，催化剂与4，4′-二碘联苯的摩尔比为0.15∶1，在150℃下回流反应7h。

Results showed that the new type rhodanine ramifications were good performance fluorescence reagents to determine the trace matter by fluorescence analysis.

同时，通过对上述试剂在测定铁、钴、铜、锡和锑时的条件的变化的研究，对这类试剂的分子结构和荧光性能的内在关系作了简要的探讨，讨论了供、吸电子基团对胂酸基偶氮若丹宁类衍生物荧光分析性能的影响。

The results showed that under the given experimental conditions,the surface layer with richiron and poor copper was formed in the surface worn region of the semimetallic friction material,the depth of organic ingredient pyrolysis caused by friction heat in worn surfaces was atout 0.35mm; the semimetallic friction material containing 15%-20%of Cu had better wear-resistance,and can form a even and continuous transfer film of copper; crack peeling was the importantmechanism of the counterpart.

半金属摩擦材料具有摩擦系数稳定，耐磨性好，对环境污染小和对偶件表面损伤小等优点，但其在摩擦热和界面应力等因素作用下，表层会发生弹性变形，塑性变形，元素扩散，组分转移和摩擦化学反应等现象，因此，利用扫描电子显微镜X射线能量色散谱和差热－热重分析，对铜纤维增强的半金属摩擦材料与灰铸铁滑动摩擦表面层的特性作了分析研究，考察了表面层特性对摩擦损行为的影响。

Controlled-release boluses are applied to ruminant animal so that the influence of bolus on the status of MDA, Cu-Zn-SOD and GSH-Px in plasma and the cha.

本研究在对青海牧区环境、牧草微量元素含量以及放牧反刍家畜体组织微量元素缺乏的情况作资料调查的前提下，有针对性的选择在青海牧区普遍缺乏的硒、钴、铜和锌这四种微量元素制成微量元素营养缓释弹丸。

As the lightning which the son of Saturn brandishes from bright Olympus when he would show a sign to mortals, and its gleam flashes far and wide- even so did his armour gleam about him as he ran.

伊多墨纽斯折回构作坚固的营棚，穿上璀璨的铠甲，操起两枝枪矛，勿匆上路，像一个霹雳，克罗诺斯之子抓在手里，从晶亮的俄波斯山上，给凡人送来一道耀眼的弧光，一个闪亮的兆示。就像这样，铜甲在他胸前闪闪发光，映照着奔跑的脚步。

And he made fifty clasps of bronze to join the tent together, that it might become one.
