Pr has little effect on the magnetic properties of (Nd1-xPrx)9.4Fe75.6Ti4B10.5C0.5 ribbons, ribbons with Br between 0.86T and 0.90T, iHc about 1000kA/m, andmax between 130kJ/m3 and 136kJ/m3 are all achieved with different ratio of Nd and Pr following their optimal crystallization annealing, which implies that it is possible to prepare high performance, low rare earth content nanocomposite Di-Fe-Ti-B-C permanent alloys with didymium directly.

Pr对合金薄带磁性能影响不大，直接利用稀土矿的次级分离产物Di来制备高性能低稀土含量纳米复合Di-Fe-Ti-B-C永磁合金完全可行，制备出的合金剩磁Br在0.86T与0.90T之间，内禀矫顽力iHc在1000kA/m左右，最大磁能积max介于130kJ/m3与136kJ/m3之间。

The matrix composites for diamond tools were tested with such modern testing instruments and equipments as DTA-7 differential thermal analyzer, JCXA-733 electronic probe and scanning electron microscope, JEM 2000 FX Ⅱ transmission electron microscope, eXL energy spectrometer, and humidity test instrument. The analysis, comparison, and induction of the testing results prove the enhancing effects of the rare earth on the matrix composites: degeneration, micro-alloying, purification, and catalytic activation. The comprehensive function of these effects leads to the decrease in the porosity of the matrix composites and to the increase in such actual indexes as the flexural strength, hardness, and impact ductility of the whole rare earth Fe-based diamond tool materials.

由DTA-7型差热分析仪、JCXA-733型电子探针及扫描电镜、JEM2000FXⅡ型透射电镜、eXL能谱仪以及莱茨2AP高温显微镜材料润湿性测试仪等现代测试仪器设备对金刚石工具材料进行了测试实验，对测试实验的结果进行了分析、比较和归纳，证实了稀土对胎体材料具有变性、微合金化、纯化和催化活化等四大强化作用机理，这些机理的综合作用导致了胎体材料孔隙率的降低和整个稀土Fe基金刚石工具材料抗弯强度、硬度及冲击韧性等实际使用性能的上升。

The dispersibility of Fe is enhanced efficiently by the introduction of silica support.

过渡金属第二组分对Fe催化剂性能的提高主要是通过对其还原程度的改变来实现的。

In this study, Fe and sodium dithionite solutions were added into Cr-spiked soils and their effects on the decrease of availability of Cr were investigated.

本研究旨在探讨将Fe或连二亚硫酸钠（Na2S2O4）等化学还原剂施於Cr污染之碱性土壤，降低有效性六价铬含量的效果。

The results show that the fine-grained hypidiomorphic pyrite, with a crystal form of pentagonal dodecahedron, contains more Au than others. Since the areas yield pyrite with relatively lower contents of main components S and Fe, while a greater gross content of trace elements, such as Cu, Pb, Zn, Au, Ag, are closely associated with gold deposits, the authors propose that a middle-scale gold deposit might be found in Zhaojiapuzi area; and there is a remote possibility to find a large gold deposit in Shengjingao area, wih a prospect of finding a concomitant gold deposit.gold deposits;mineralogical.

结果表明以五角十二面体晶形为特征的半自形细粒状黄铁矿含金性较高；黄铁矿主成份S、Fe含量相对低，而黄铁矿中Cu、Pb、Zn、Au、Ag等微量元素总量相对高的黄铁矿分布区城与金矿化关系密切；提出赵家堡子地区具备找到一处中型以上金矿的前景，而在生金皋地区找到大型金矿床的可能性很小，但有望找到伴生金矿床。
