As a result, some ideas about the fabrication are put forward.The EPMA experiment results show that the main element such as W, Mo, Ti, Ni, Cu, Fe element are changed gradually in W-Mo and W-Mo-Ti FGM. In the layer rich in W, the grain are intervained and are mixed mechanismly. The same is to the layer rich in Mo and W-Mo. These grain felt up by some sinter. In Mo-Ti layer rich in Mo, the grains are also mixed mechanismly. Ni, Cu, Fe element assembled at interface. Ni melt by Cu plays an vital role in sinter effect. The microstructure characteristics result show that the compactness of W-Mo and W-Mo-Ti FGM is good.

电子探针实验结果表明W-Mo系、W-Mo-Ti系梯度功能材料中主要元素W、Mo、Ti、Ni、Fe、Cu分布整体上具有梯度变化规律，发现富W区、富Mo区、W-Mo混合区中颗粒交错分布，基本上以机械混合的形式存在，颗粒之间主要靠烧结剂的粘结作用实现致密化；以Mo为主要组分的Mo-Ti混合区，也是以机械混合的形式存在；Cu溶解于Ni形成固溶体更好地起到活化烧结能力，Ni、Cu、Fe在宏观层间界面富集，有利于烧结致密化。

E The fractal and spherical particles exist favorably in the coarse fraction, while in the fine mode (0μm) are floccules formed by flocking fine particles together, containing crustal elements and mainly being silicates and aluminosilicates. f The content of Al, Si, Fe in TSP samples is higher than in PM〓, indicating an enrichment of these elements in coarse mode. g Compared with non-dust particles, the dust particles are more homogeneous in terms of morphology, particle size and composition. h Particles with irregular shape and well-distributed size dominate in dust samples, containing crustal elements such as Mg, Al, Si, Ca, Fe et al.

细粒中除小圆球外，大多为细小颗粒聚结在一起的不规则块状颗粒，主要含地壳元素，可能是硅酸盐和铝硅酸盐。fMg、Al、Si、Fe在PM〓中的含量较相应的TSP中的低，可见这些元素主要存在于较粗颗粒中。g沙尘期气溶胶粒子的形貌较非沙尘期单一、均匀，非沙尘气溶胶粒子的形貌、组分较沙尘期复杂。h沙尘期样品中，粒径均匀、形状不规则的颗粒最多，这些颗粒主要含地壳元素Mg、Al、Si、Ca和Fe等，是典型的由源区传输过来的沙尘粒子，但其高硫含量表明在青岛特殊的地理环境下，在粒子表面发生了硫的均相和非均相反应。

In comparison with the Fe-SA/mCS BFM modified by Fe(superscript 3+), the membrane impedance, IR drop and swelling degree of the CuPc8-SA/CuTAPc-CS BPM all obviously decreased.

与Fe(上标 3+)改性的Fe-SA/mCS双极膜相比，CuPc8-SA/CuTAPc-CS双极膜的阻抗、电阻压降和溶胀度降低。

The source of Fe was provided strong supporting evidence. Iron isotopic ration of BIF has the positive dependence ofδEu, indicating the source of Fe correlation with hydrothermal fluid.9. A model for Fe cycling.

首次从成矿元素本身为BIF的物质来源提供直接证据：BIF的Fe同位素成分与Eu异常存在非常明显地正相关关系，这清楚地表明鞍本地区BIF中铁的来源与海底火山热液活动有关。9。

Results bmscs could be effectively labeled by fe. the labeled cells appeared light-yellow or deep-yellow under microscope, which was dependent on the dose of fe.

结果 fe可以高效率标记bmsc，被标记的细胞在显微镜下呈淡黄或深黄，颜色深浅与所加fe 的剂量呈正相关。

The Ti-ion was replaced 100% by Fe、Nb on the octahedra B sites in the SrTiO_3, and the mole percentage of Fe、Nb were changed to be in accordance with the components of A_nB_nO_(3n-1) and A_mB_mO_(3m+2) series of the perovskite that n、m are integer.

介绍用Fe、Nb对SrTiO_3中八面体B晶位上的Ti离子进行百分之百的取代，调节Fe、Nb的摩尔百分比，使其符合类钙钛矿的A_nB_nO_(3n-1)及A_mB_mO_(3m+2)系列n、m取整数的组分。

However, because S is more easily combined with Fe than As does, hence when hydrothermal fluids are rich in S, the possibility of As presence in pyrite crystal lattice decreased, but the chance for Co and Ni to substitute Fe in pyrite crystal lattice increased, thus S rich is not favorable for the formation of P type of pyrite.

但另一方面，由于S与As相比更易与Fe结合，因而成矿介质中富S将使As进入黄铁矿晶格中的能力或几率降低，并进一步使Co、Ni因补偿类质同像进入黄铁矿晶格中代替Fe的能力或几率增大，反而不利于形成P型黄铁矿。

In the process of purification by ammonium, Fe~(3+)、Fe~(2+)、Al~(3+)、Cr~(3+)、Ni~(2+) could be separated for their different solubility product.

在氨水除杂过程中根据Fe~(3+)、Fe~(2+)、Al~(3+)、Cr~(3+)、Ni~(2+)等各自溶度积不同进行分离、除杂净化。

With intention of developing an advanced heat resistant alloy for gas-turbine engines,alloys based on Fe-25Cr-6Al and Fe-25Cr-11Al have been prepared by mechanical alloying andhot extrusion.

为发展一种可用于燃气轮机的新型耐热合金，用机械合金化及热挤压工艺方法制备了以Fe-25Cr-6Al 和Fe-25Cr-11Al 为基体成分的合金。

Turf leaf lamina comes shorter, narrower and thicker, if supplying Fe on leaf surface at summer. It makes Canopy height lower by 0.5-0.8cm, so we can improve sight effect of turf by supplying Fe. The distribution range of roots extended, so the drought tolerance improved.

夏季叶施Fe使草坪叶片变短变窄变厚，草坪自然降低0.5—0.8cm，可用叶施Fe来提高草坪的景观效果；也使草坪的根系分布范围扩大，增加了假俭草草坪的抗旱性。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
