In other words, the results novelty broke the conclusion in the pervious reports that combustion synthesis can't occur once Fe content in Fe-Ti-C system is more than 60wt%, and gave more engineering meaning to combustion synthesis of iron-based composites.

而这正是本研究的创新点之一，即打破了前人研究所得出的"Fe-Ti-C体系中Fe含量超过60wt％就不能实现燃烧合成"的界限，从而使Fe-Ti-C体系燃烧合成制各铁基复合材料更具有工程意义。

采用光学显微和扫描电子显微观察等方法，系统地研究了Fe-Al系铁磁性阻尼合金的微观组织，考察了合金元素、热处理工艺对合金阻尼性能和力学性能的影响，探讨了Fe-Al合金产生高阻尼特性的微观机制以及Fe-Al系高阻尼合金的同质和异质焊接性能。

It is found that there is a mineral association, micro-crystal muscovite and phengite, in this deposit. The mineral assemblage contains about 80% micro-crystal muscovite and about 20% phengite. Their crystallinity is very high and their polytype is 2M1. Both of them are dioctahedral because the d and b of micro-crystal muscovite and phengite are 0.1502 nm, 0.9012 nm and 0.1505 nm, 0.9030 nm, respectively. For their d and b are larger than those of common muscovite, the reason why Fe(superscript 2+)+Fe(superscript 3+) and Mg(superscript 2+) are high in the ore is that Al(superscript 3+) in the octahedron is replaced by Fe(superscript 2+)+Fe(superscript 3+) and Mg(superscript 2+), and this is a phengite series mineral association formed through isomorphic replacement.

该矿物组合中的微晶白云母和多硅白云母结晶度高，多型为2M1，其含量分别为80%和20%左右；二者都属二八面体型白云母类矿物，但d060和b值偏大，微晶白云母的d060=0.1502nm，b=0.9012nm，多硅白云母的d060=0.1505nm，b=0.9030nm；微晶白云母矿铝含量较低、铁镁含量较高，其原因是白云母晶体铝氧八面体中的Al离子被Fe、Mg等离子所取代，这一矿物组合是通过矿物类质同象作用所形成一种多硅白云母系列矿物。

Fe, N+Fe fertilizing at autumn can delay caducity, put scorch date backward by 2-6 day. Bring Regreen date foreward by 4-8 day at second year. Especially treatment of 4g/m2 N+0.61/m2 Fe can makes green periods reach 325 day, excesses comparison 15 day

秋季叶施Fe、N+Fe可延缓衰老、使枯黄期推迟2—6d，翌年草坪提前4—8d返青，尤其4g/m~2N+0.6l/m~2Fe可使假俭草草坪的青绿期达325d，比对照的310d延长了15d。

Chemical analysis showed that the fresh basalts and corestones slightly changed in composition except that variations in Fe(superscript 2+) to Fe(superscript 3+) are most noticeable. In the course of corestones changing to saprolite elements of Si, Ca, Na and Mg, the ratio of SiO2/Al2O3 decreased gradually, while the elements of Fe, Al and the values of LOI and CIA significantly increased.

化学全分析结果表明新鲜玄武岩与核心石在除Fe外，其它组分无明显的改变；核心石在转变为腐岩过程中Si、Ca、Na、Mg等元素逐渐流失，Fe、Al等逐渐富集，同时烧失量LOI和化学蚀变指数CIA显著增加，硅铝比逐渐减少。

As pyrites from Archean black shales worldwide show similar Fe iso- tope features to those from the two Chinese sulfide deposits, the enrichment of light Fe isotopes in early Precambrian ocean is likely to be regional, or even global.

导致早前寒武纪海洋富集Fe轻同位素的原因是海水中大量的Fe被氧化形成了富集Fe重同位素的磁铁矿和赤铁矿。

The results indicate that the main phase of the nephrite cat's eye is tremolite,and the main impurity ions are Fe~(3+), Fe~(2+) and Mn~(2+).

软玉猫眼的主要杂质离子为Fe~(3+)，Fe~(2+)和Mn~(2+)，其Raman吸收频率主要出现在940～1105，650～760cm~(-1)和450～510cm~(-1)范围内。3600～3800cm~(-1)范围内—OH伸缩振动Raman谱带分裂，并向低波数方向位移，这主要与Mg~(2+)和Fe~(2+)的含量有关。

Doped high consistence Co can't increase the density of defect levels. ZnO doped Fe is different from doped Mn or Co totaly, the density of photoelectrons anddefect levels aren't reduced obviously. It's probably related the valence of Fe in crystal,general think trivalence of Fe, and form donor levels in ZnO.

Fe掺杂的ZnO完全不同于Mn、Co掺杂，其光生电子密度没有因掺杂出现明显的降低，即缺陷能级密度没有降低，这可能和掺入ZnO所呈现的价态有关，一般认为Fe为三价态，在ZnO中形成施主能级。
