查询词典 soft iron

Except for research and discuss on turning and milling gray cast iron under high cutting speed, only few studies about machining nodular cast iron and vermicular cast iron with PCBN tool were carried out, while the two materials are widely used in manufacturing, specially automobile, aviation and machine tool. Therefore how to cutting these hard-to-machine materials economically and effectively is becoming an urgent-to-solve problem.

但是对于铸铁加工领域的研究则相对较少，除了对高速切削和铣削灰铸铁有较为深入的研究探讨外，关于PCBN刀具对球墨铸铁、蠕墨铸铁等材料加工应用的研究却很少，而这两种材料近些年已经大量的应用于汽车、航空、机床等制造业中，因此如何经济有效的加工这样难加工材料成为迫切需要解决的问题。

Al impurity, the floatabilities of hematite and aegirine were resemble, which is contributed to the existence of structrual iron ion on surfaces of both minerals. It is the structrual iron ion that accelerates the floatability of aegirine greatly and leads to difficult separation with hematite. 2. The basic mechanism of actions of fluorosilicate salts as selective depressants of aegirine during the direct flotation of hematite was investaged detaily by using FTIR and XPS spectrocppy, fluorosilicate salts are poor depressants for hematite, but are very strong depressants for iron-containing silicate such as aegrine in weakly acid medium, which can enlarge the flotation differences between two minerals.

运用X射线衍射、俄歇能谱等测试手段研究了赤铁矿与钠辉石纯矿物的晶体结构特征，表面破裂面的元素组成与赋存状态，发现在白云鄂博不同的矿床（氧化矿段，原生矿段，风化矿段）存在着三种颜色与可浮性均有所差别的钠辉石，其可浮性的差异主要是由于表面含铁量及Ca、Al等杂质含量的不同而引起的，结构Fe〓的存在导致钠辉石可浮性剧增从而与赤铁矿难以分离。

The main principle of the DCcontactor:The electromagnetism coil switches on electricity thetitle iron to match with the iron heart on,the suction of theelectromagnetism system overcomes the counterforce of the springarouses the action of the contact, the main electric circuitconnected;The electromagnetism coil cuts the power the counterforceof the spring arouses the title iron from move to open, the headcontact breaks to open the output electricity arc give or get anelectric shock in drive to arc-extinct-chamber and made longer,thestrong cooling dissociates and put out,the main electric circuitcuts off.

接触器的主要原理：电磁线圈通电，衔铁和铁心吸合，电磁系统的吸力克服弹簧的反作用力带动动触头与静触头接触，主电路接通；电磁线圈断电，弹簧的反作用力带动衔铁和动触头弹开，触头断开产生的电弧在灭弧室中受到磁吹灭弧和电动力驱动被拉长，并强烈冷却去游离而熄灭，主电路切断。

The reduction temperature has great influence in constituting slag and iron phase coacervation. High temperature will add iron phase carburize and fall down melting and accelerate iron phase coacervation.

Part II:The electrocatalytic oxidation of guanine, adenine, guanosine-5'-monophosphate and ssDNA was performed in the presence of iron bis(2,2':6',2"-terpyridine) and Fe tris(1,10-phenanthroline) complexes as a homogeneous catalysts with Fe redox couple. The electrocatalytic and electroanalytic properties of guanine with an iron bis(2,2':6',2"-terpyridine) complex was measured by the amperometry method using the rotating disk electrodes. Electropolymerization of iron tris(5-amino-1,10-phenanthroline) complex produced thin polymer films on a gold, platinum, nickel, and glassy carbon electrode.
