1岩石的滑动摩擦系数与岩石矿物性质的关系显示文摘本文试图对印度的几种岩石的滑动摩擦特性作出评价,这几种岩石的地质成因模式大为不同,它们代表了几个主要的地质层组并与边坡稳定性有关.还研制了室内试验用的倾斜平面仪等,以进行本项研究工作.滑动磨擦系数的确定,采取两种子先裂开的岩块,即天然裂隙面和锯开面,裂面均呈接触状态,以模拟粗糙的和光滑的不连续面.其结果表明滑动磨擦系数依赖于不同岩性的矿物性质.没有变质的石英、长石、无水的镁铁质矿物和方解石等占优势的岩石显示出较高的摩擦系数(μ_k)值(0.6~0.8),而那些具有15%或更多的含羟根矿物成分的岩石则显示较低的(μ_k)数值(0.5~0.6).Y.V.拉马纳 B.S.戈格特 黄彻元 1992西北水电1992,,1:3

6使用固体还原剂提高含铁低品位锰矿石的锰铁比显示文摘低Mn/Fe比的低品位锰矿石,能通过选择性的碳还原使氧化铁还原成磁铁矿,然后利用磁选分离出磁铁矿而得以富集。热解重量分析(TGA)被用来评价纯MnO和Fe_2O_3采用固体碳时的优先等温还原状况。然后对人工合成的类似于实际低品位矿石(即印度桑德锰矿石)的化合物进行还原。锰矿的碳热还原使赤铁矿和针铁矿矿物转化为磁铁矿(Fe_3O_4),磁铁矿随后进入磁性产物,最终非磁性产物中含铁量大为减少,而锰含量增加。研究结果表明:可以使含铁量从22%降低到5.85%,锰回收率50%左右时Mn/Fe比从1.52增加到6.2,把磁性产物磨列-75μm,能进一步提高锰回收率。Y.V.斯瓦达 B.布霍伊 S.普拉卡什等 雷贵春 1999现代矿业1999,0,8:1

15Ge/Si混合物纳米薄膜中Ge钠米颗粒氧化态的XPS研究(英文)显示文摘The oxidation states of Ge nanoparticles in the surface layer of Ge/Si film were studied by X-ray photoelectron spectroscopy. New features appeared at the high binding energy side of the XPS Ge 3d peak when samples were annealed in atmosphere, which were caused by the large interfacial area between the Ge and Si nanoparticles, as well as by the change in environment of the Ge nanoparticles and the oxidation states of Ge and Si.C.
