The stability of copper reduced because of the formation of copper oxide under alkaline condition, while the stability of copper kept the same because of the constant chemical structure under near neutral condition.

在去离子水中， Cu-KEtX的化学结构则没有明显的改变，故对Cu的稳定性亦不变。

A preparation method of monodisperse high crystallinity copper powder is provided, which relates to a method for preparing copper powder used in conductive paste by using cupreous compound, in particular to a preparation method of the copper powder used in the conductive paste that is applicable to ceramic electronic components with a plurality of layers.

一种单分散高结晶度铜粉的制备方法，涉及用铜的化合物制备导电浆料用铜粉的方法，特别是涉及适用于多层陶瓷电子元件的导电浆料用铜粉的制备方法。

It was rev ealed that:cuprite,malachite and tenorite are the three main kinds of copper-bea ring minerals which would be supersaturated when Cu concentration in the solutio n is high enough(higher than 0.0016 mol/L,0.0079 mol/L separately) under the stu dy conditions.Copper exists in the solution mainly as the species of CuCO3 ,Cu2+ and CuOH+.The corresponding content of CuCO3 would be decrea sed following the deposition of the copper-bearing minerals,nevertheless,Cu2 + and CuOH+ would be increased.

模拟结果表明，在土壤中常见的E h和pH及研究区的年平均温度条件下，溶液中铜离子的含量达到一定的浓度时，可以生成赤铜矿(当Cu≈00016 mol/L)、孔雀石及黑铜矿(当Cu≈0 0079mol/L)等次生矿物，溶液中Cu的存在形式也发生了变化，即CuCO3所占的比例不断减小，而Cu2+和CuO H+的含量则相继增高，且Cu2+的增幅大于CuOH+。

It was also found that at experimental concentrations there was no regularity for the change of activity of copper salicylate encapsulated in negatively charged liposomes, and copper salicylate encapsulated in liposomes with more negative charges could promote the dismutation of superoxide anion free radicals, however, so could copper salicylate encapsulated in liposomes with fewer negative charges only in lower concentrations.

并发现在实验浓度范围内，负电性脂质体包裹的水杨酸铜，活性变化无规则，且荷负电量多的脂质体包裹的水杨酸铜促进超氧自由基的歧化，而荷负电量少的脂质体仅在低浓度区对超氧的歧化表现为促进作用。

Copper clad steel grounding pole is made by special electroform technique that is using 99.9% pure copper cover on the core of mild steel equally, which makes the copper and steel core entirely molecule bond (if not bonding tightly , the primary battery reaction will occur when electrifying,anode metal iron generates oxidation reaction to be iron-ion and losing, it accelerates the corrosion of steel core).

铜包钢接地极是用特殊的电铸技术将99.9%的纯铜均匀覆盖到低碳钢芯上，使铜与钢芯完全分子结合（如两者结合不密，在通电的情况下，会产生原电池反应，阳极金属铁发生氧化反应变成铁离子流失，反而加快钢芯受蚀）。

The results show that the major crystalline phases present in the Noranda copper slag are fayalite, magnetite, copper matte, glassy phase as well as small amount of metallic copper.

结果表明，诺兰达铜渣的主要矿相为铁橄榄石、磁铁矿、铜锍、玻璃相和少量金属铜。

The result of situ-FTIR study on the process of dehydrogenation of CHL, we concluded the reaction mechanism, and proved that monovalence copper had more activity than zero valence copper and the side reaction mainly took place on zero valence copper.

通过对环己醇脱氢反应过程的原位傅立叶变换红外光谱研究，推导出了反应机理，得出Cu〓较Cu〓更具有环己醇脱氢活性，环己醇脱氢的副反应主要发生在Cu〓上。
