The result shows that modification can make the β-Si phase thin when the joining amount is 0.3wt%, making the best modification result. Alloying elements Mn and Ni are always used to neutralize iron"s harm in aluminum alloys. They can form many kinds of complicated metallically compounds with Fe and Al, and eliminate needle-like iron-rich phases to reduce iron"s harm in Al-Fe alloy. Copper makes the alloy microstructure thick and electromagnetic stirring obviously makes the alloy microstructure thin, round the second phase, when the stirring voltage is 200V, making the best result; Reheat makes liquid phases emerge in the alloy, when the warming temperature is 650?

研究结果表明：红磷可以明显细化合金中的初晶硅，当加入量为0.3wt%时，取得最佳变质效果；锰、镍合金中加入后，通过形成多种复杂金属间化合物，细化针片状富铁相，减小铁对铝硅合金性能的危害；铜使合金微观组织发生粗化；电磁搅拌明显细化合金组织，使第二相圆整化，搅拌电压为200V时，取得最佳细化效果；二次加热使合金组织中产生部分液相，在650？

The four-colour offset printing press Heidelberg, if a printing plate surface is a zinc or zinc or iron, iron will and Bailers in acid solution from chemical replacement reaction secable, nitrous oxide, drum body cannot ¤j¤?¤? backing and a printing plate, such as the drum surface long soaked in the acid corrosion, instilla secable, a printing plate chrome coated drum for restructuring into it or nickel does not result in more accidents.

四色海德堡胶印机，如果印版滚筒暗地是涂锌或铁，那么锌或铁城市与水斗溶液边的酸起化学置换不正答生锈、氧化，滚筒体不克不及紧贴衬垫物和印版，如滚筒背恒久泡在酸液边，会爆发腐化生锈，印版滚筒体改成涂铬或镍不离不会爆发以上变乱。

Diamond single crystals were synthesized at a cubic press under high-temperature and high-pressure with the sheeted powder metallurgical iron-based catalysts, which were added by moderate copper powder.

以铁、镍单质金属粉和适量的电解铜粉为原料，采用粉末冶金方法制备规格为Φ15×0.5mm的片状铁基触媒，在六面顶压机上高温高压合成金刚石单晶。

It shows that mechanical activation makes the activity of iron increase sharply and enhanced its replacement reaction ability. Succeedingly, the recovery of copper and nickel is improved.

在铁粉置换法中，利用机械活化可以增强铁粉的活性，从而增大从溶液中置换铜镍的效果。

The optimal mass concentration of major salt for coloring ferroxyl color and coloring archaized green ...

通过正交实验确定了黄铜着铁锈色、黄铜着仿古绿色的最佳主盐质量浓度，分别为：50 g/L硫酸铜，100 g/L氯化铁，50 g/L氯化亚铁；20 g/L硫酸铜，5 g/L氯化钙，4 g/L氯化镍。

The relationship between coating microstructure and electromagnetic properties of electroformed Ni-Fe alloy s was studied.

研究了电铸镍铁合金制备过程中工艺条件对电铸层成分的影响，获得含铁质量分数20%电铸层的最佳工艺条件为镀液硫酸亚铁含量6g/L、pH值2.5、温度55℃、电流密度3.5A/ dm~2；讨论了镀层形貌及电磁性能的变化关系。

So, it is better to control the iron reduction degree to be 60%. Correspondingly, the leaching rate of nickel and iron is about 85% and not over 30%, respectively.

因此铁还原度控制在60%为宜，相应的镍浸出率约为85%，而铁的浸出率不超过30%。

As the Fe content x is larger than or equal to 0.2, the crystal structure of the alloy is single-phase body-centered cubic .

铁镍合金纳米片的平均直径为50nm，平均厚度小于10nm，平均厚度随铁含量的提高而减小。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.
