It is also the main factors to control the abundances of noncrystal phase. The typical feature is that the elemental concentrations in this speciation and the percentages of this speciation in samples have significantly variation down the core, especially there is a sharp change at the depth of 80cm.

3铁锰氧化物结合态是除残渣态外的又一元素主要赋存形态，是控制元素在非晶质结合态中赋存的主要因素，同时也是岩芯不同深度沉积物中元素含量和萃取比例变化最大的一个相态。

During the period of the mineralizing, the surroundings of studying are is continental facies. The aggraded materials who have experienced long time efflorescence and leaching have corrosion and eluviated the alkali metals, alkaline earth, silicon, iron and so on. The schwer l Al2O3 is keeped down. So this condition made the enrichment of the aluminum and the bauxite is formed.

铝土矿成矿时期，研究区为陆相环境，已沉积物质在炎热潮湿的气候条件下经历了长期的风化淋滤作用，将碱金属、碱土金属、硅、铁等溶蚀淋滤掉，难溶的Al2O3残留下来，造成铝的富集，形成了铝土矿。

A compartmented soil-glass bead culture system was used to investigate characteristics of arsenic accumulation in iron plaque and in mature rice plants irrigated using water with arsenic in greenhouse.

结果表明，水稻的秸秆生物量及其籽粒产量并没有受到不同来源砷的显著影响；灌溉含砷水处理的两品系水稻根表铁氧化物沉积的数量（YY-1：196 g.kg^-1，94D-64：75.8 g.kg^-1）高于对照（YY-1：175g.kg^-1，94D-64：60.1 g.kg^-1），但差异不显著。

Conventionally the layers have been divided into A, B and C horizons. The A horizon is the upper layer, containing humus and is leached and,or eluviated of many minerals. The B horizon forms a zone of deposition and is enriched with clay minerals and iron,aluminium oxides from the A layer. The C layer is the parent material for the present soil and may be partially weathered rock, transported glacial or alluvial material or an earlier soil.

传统上可将土壤分成A、B、C三层。A层是位於最上面的一层，含有腐殖质，许多矿物质在该层中沥滤和淋溶。B层是个沉积区，富集了大量的来自A层的粘土矿物质和铁，铝氧化物。C层是现在土壤的母质层，也可能是风化的岩石、来自冰河或冲积层的物质、或早期土壤遗留下来的。

Using hydrotreated gas oil as solvent, under the conditions of a reaction temperature of 400 C, a hydrogen partial pressure of 10 MPa and a reaction time of 1 h, a portion of coke deposits could be removed yet without the function of hydrogenating coke.

采用溶剂萃取法除去工业失活催化剂上沉积的焦炭和金属的研究结果表明，用四氢呋喃、吡啶和喹啉这3种含杂原子的有机强溶剂常温萃取催化剂，其去除焦炭能力很弱，而且会因这些溶剂的强吸附作用污染催化剂；盐酸洗涤能有效去除催化剂表面的钙、铁沉积层，但不能去除焦炭；低芳香性的加氢瓦斯油在400 C、H2压力为10MPa、反应1h的条件下可部分去除催化剂上的焦炭，但不具备强的氢化焦炭作用；1，2，3，4-四氢化萘因具有供给原子氢的能力，可以有效地氢化和去除催化剂上的焦炭。

Composite structured samples of glass-coated Fe-based nanocrystalline wires deposited with a layer of copper by magnetron sputtering method were prepared.

采用磁控溅射法在铁基纳米晶玻璃包裹丝外沉积铜层，研究了细丝在驱动电流流过不同层的巨磁阻抗效应。

Thermodynamic analysis and chemical vapor deposition of pyrolytic carbon on the surface of needle-like goethite in a flow reactor were carried out.

采用流动反应器研究了丙烯热解和在铁黄颗粒表面生成热解炭的化学热力学以及化学气相沉积过程。

First, the cobalt hydroxide is mainly adsorbed on the crystal surface (021) and (100), but not on the main crystal surface (110) of iron hydroxide.

1Co〓在铁黄晶面的沉积主要发生在端面(021)和侧面(100)，而不是(110)晶面。

The iron hydroxide particles prepared above were coated with cobalt by surface adsorption-precipitation reaction. The low pH and Co〓 concentration of suspended system can prevent the nanoparticle from heterocoagulation. The saturation magnetization of MP particles with uniform cobalt hydroxide layer is 10％ higher than that of the α-Fe. And a close SiO〓 layer can improve the coercivity by about 92％.

铁黄粒子表面吸附-反应沉积钴过程中较低的pH值和浓度有利于形成均匀的钴氢氧化物包覆层，可避免形成异相凝聚现象，使比饱和磁化强度提高10％；表面包覆二氧化硅形成致密的薄膜，使矫顽力提高92％。

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。
