含铁

In cold desert soils, rubification results in relatively high concentrations of Fe〓 in soil profile. Stained depth increases progressively with time.

土壤剖面上部的染色作用也比较显著，是由于土壤母质中含铁矿物的氧化作用造成的。

The reduction of ferric oxide may result from the Fe phase, which would increase the electrical conductivity of B〓C coating.

涂层中金属Fe杂质相的存在，使得它的电导率同含铁量低的碳化硼粉末所制得的涂层相比出现明显偏高。

Because of these particles of ferruginous or other soluble pigment, the world turned red.

因为这些含铁的或者其他水溶性的色素，整个世界变红了。

The results of mineralogy show that the main ferrous mineral is fine magnetite, which exists in ferruginous glass partly as inclusion texture.

工艺矿物学研究结果表明：该渣中主要含铁矿物的嵌布粒度细小，且部分以微细包裹体形态分布于成分复杂的铁质玻璃体中，采用常规磁选工艺无法有效回收。

The results show that the distribution of gold deposits in this area are obviously controlled by regional tectonics, and alterations related to gold mineralization are composed mainly of silicification and ferruginous minerals, with...

研究表明，本区现有矿床分布与明显受区域构造控制，区内金矿床围岩蚀变以硅化和含铁矿物为主，粘土矿物蚀变较少。

It was concluded that a noble and base metal metaflogenic series was composed of the inner part of BIFs and ferruginous rock series. And mantle plume had close spatio-temporal and genetic relationships with BIFs. In anoxic environment in Precambrian, the anaerobic bacteria would provide oxygen for ferruginous deposition during photosynthesis.

认为BIFs内部以及包括BIFs在内的含铁岩系均构成贱、贵金属成矿系列；地幔柱与BIFs之间存在密切的时、空和成因联系；在早前寒武纪缺权的环境下，厌氧的细菌类生物通过光合作用为BIFs中铁质沉淀提供了氧。

The beheviour of four low-molecule weight organic acid lactic acid,hydroxy-acetic acid,mercapto-acetic acid,glyconic acid as iron-containing silicate-aegirines depressants on the hematite direct flotation is investigated in this paper.The results of flota

本文研究了四种小分子有机酸抑制剂乳酸、羟基乙酸、巯基乙酸、葡糖酸在赤铁矿正浮选中对含铁硅酸盐脉石霓石的抑制行为，纯矿物、人工混合矿与实际矿石浮选实验均证明了它们具有良好的选择性抑制作用，可以成功地实现赤铁矿与霓石的浮选分离。

The condition and efficiency of removing fluor of this material were studied.

实验研究了该种含铁改性分子筛除氟材料在高氟水中的除氟效率和条件。

The direct flotation tests of hematite from real samples of high intensity magnetic separation concentrate in weak acidic medium with fluosilicate or polymer silicic acid colloid as the depressor of iron containing silicate gangue natrosiderite and with anionic fatty acid sulfonate as the collector have all achieved good separation results.

针对包钢强磁精矿实际矿石样，分别以氟硅酸盐、聚合硅酸胶体作为含铁硅酸盐脉石霓石的选择性抑制剂，以阴离子脂肪酸磺酸盐为捕收剂，在弱酸性条件下进行赤铁矿的直接浮选，均取得了较好的分选指标。

4 Months of age should be more iron-rich as well as digestion and absorption by the baby food, egg yolk is the most suitable.

3－4个月的婴儿应该含铁较丰富，又能被婴儿消化吸收的食品，鸡蛋黄是最适合的。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
