铁的

Among the investigated meteorites, Dong Ujimqin Qi, Weiyuan mesosiderites and Ningbo iron meteorite were recovered in China, and Rafruti ataxite was found in 1886 in Switzerland.

在所研究的4个陨石中，东乌珠穆沁旗、渭源{类型Ⅲ中铁陨石及宁波铁陨石是在中国回收的，另一个无结构铁陨石Rafruti是于1886年在瑞土发现的。

And brought out the people who were there, consigning them to labor with saws and with iron picks and axes, and he made them work at brickmaking. He did this to all the Ammonite towns.

将城里的人拉出来，放在锯下，或铁耙下，或铁斧下，或叫他经过砖窑（或作：强他们用锯，或用打粮食的铁器，或用铁斧做工，或使在砖窑里服役）；大卫待亚扪各城的居民都是如此。

In this paper, the Iron-oxide-coated sand absorption character prepared in different temperatures was studied, mainly tested its absorb hexad chromium, and the inherent reason that formed this differences was explained.

本文研究了不同温度下制备的铁覆膜砂吸附性能的差异，对铁覆膜砂吸附Cr的性能进行了综合的测试，说明了形成这些差异的内在原因制备温度对IOCS的吸附性能有显著影响，一般低温制备的IOCS要比高温制备的铁覆膜砂吸附性容量较大，去除效率较高；覆盖在石英砂表面的铁氧化物在不同的焙烧温度下形成了不同的物质，110℃的低温一般形成FeOOH，而600℃高温下形成的则为α-Fe2O3。

Base on above studies, some conclusions were obtained as follows:(1) ore-forming background of the studied ferromanganese crusts are mainly controlled by intensity of Antarctic Bottom Waters and variations of material source;(2) it is confirmed that the ferromanganese crusts are mainly hydrogenetic and their composition are affected by volcanic and continental material simultaneously; there are no obvious phosphatization reconstruction and element reaction occurred in them, so they have important paleoceanological significance;(3) from researches on element occurrence modes in the new-type ferromanganese crusts and the lying sediments, it is proposed that there is no great biological affection on the crusts formation and their composition mainly came from the adsorptive action of the ferromanganese oxides in them;(4) two major types of ore-controlling factors are identified through compilation of ore-controlling factors, which are geological and oceanic factors;(5) considering the long-term variation trends of the crusts composition, combing the U-series and 10Be isotope dating results, it is proposed that the ore-forming processes of ferromanganese crusts in the studied areas can be divided into three major stages (5.6~2.8 Ma, 2.8~2.7 Ma and since 2.7 Ma), and then the activities of AABW since the Late Miocene, changes of input flux coming from volcanic and continental material are confirmed.

通过研究，得出如下结论：(1)研究区铁锰结壳的成矿背景主要受控于南极底流强弱及物源供给的变化；(2)证实铁锰结壳主要为水成成因，同时其物质组成也受一定程度的火山和陆源物质的影响；结壳自形成以来没有遭受到明显的磷酸盐化等成岩后期改造和元素再迁移，具有重要的古海洋学意义；(3)通过新型铁锰结壳及下伏沉积物元素赋存状态的研究，认为生物作用对研究区结壳的形成并没有很大的直接影响，其物质成分主要来自于结壳中铁锰氧化物的吸附作用；(4)在控矿要素的研究中，归纳出了地质与海洋两大类结壳控矿要素；(5)根据结壳成分长周期变化趋势，结合铀系和10Be测年结果，将研究区结壳的形成过程划分为三个主要阶段(5.6~2.8 Ma，2.8~2.7 Ma和2.7 Ma以来)，并确定了晚中新世以来研究区南极底流的活动情况、火山和大陆来源物质输入量的变化。

These compounds are of substantial interest both inviewpoints of theory and practical applications, mainlyunder the stimulus to achieve synthetic models either foractive sites of iron-sulfur proteins or for transitionmetal catalysts. This thesis describes the synthesis, structures andconformations of 51 new iron-sulfur cluster complexes,which have been characterized by elemental analysis andstandard spectroscopic methods. In addition, single-crystalX-ray diffraction analyses were performed for 4 representa-tive new compounds. Reactivities of μ-〓 with mono- and di- Grig-nard reagents derived intermediates toward various organicelectrophilic substrates were studied, along with complexa-tion of arynyl-containing iron-sulfur clusters by 〓Thus, several bridged, non-bridged, monomeric, dimeric,homonuclear, heteronuclear iron-sullfur and iron-sulfur co-balt-carbon cluster complexes were synthesized. A novelreaction and convenient route for the synthesis in highyield of tetranuclear iron complexes 〓 containing atetracoordinated sulfur atom was discovered, whereas aplausible mechanism based on experimental results was propo-sed for the formation of the new cluster type.

鉴于有机铁硫原子簇化学在基础理论发展和应用方面的重要意义，因此我们开展了这一课题的研究，并取得以下主要成果： 1、本文共合成了51个新有机铁硫及含钴碳簇基的有机铁硫原子簇配合物，除用元素分析，NMR，IR，MS法表征其结构和构象外，还用X-光衍射技术测得四个代表性配合物的单晶结构和构象； 2、我们业已发现炔基Grignard试剂同〓可形成一种&开环&与&闭环&中间物的平衡混合物，研究该平衡混合物同各种亲电试剂的反应； 3、研究发现了一种可高产率地形成〓含〓四配位硫挛合簇的新化学反应并对此反应提出了—种有趣的反应机理； 4、首次由1，4-二溴丁烷双Grignard试剂与〓制得一种新型铁硫簇双硫阴离子活性中间体，并进而研究了它的亲核反应性能； 5、找到了通过〓的光化学反应来合成簇合物〓-〓的一条有实用价值的新路线。

And the scientific research showed that they are medicable to insomnia, anxiety and other diseases that found in modern people. 4 The regression models of biomass were used to calculate the total cumulative biomass. Average biomass of six samples was 62.88 t·hm-2 after cutting 3 years, which was higher than that of tropical secondary forests with 5 years succession. It can be concluded that traditional fuel woods had played an important role in conservation of tropical forest in the area. Caloric values were not different in major fuel species (Coefficient of variation was only 1.1%). The similar result was found in stems of C. siamea after growing different years. The main reason of C. siamea cultivation was that it had the character of hardwood, easy collecting, little ash, and so on.

铁刀木的各个部位都作药用，资源量大的树叶和心材使用最多，并且现有的研究成果表明它们具有多种活性成分，针对现代人常患的失眠、焦虑等疾病具有较好疗效。4）通过收获法拟合的生物量回归模型对推测西双版纳地区铁刀木林薪柴蓄积量有较高的参考价值，砍伐3年后的六个样方中铁刀木的平均生物量为62.878 t.hm-2，高于5年林龄的热带次生林（16.35t·hm-2），对西双版纳热带雨林的保护有着重要意义。5）几个村寨最主要的薪材树种热值研究结果变异系数仅为1.1％，各薪材树种之间热值相差不大，铁刀木被选择为传统薪炭林更多是因为材质坚硬、收获运输方便、燃烧完全等特点。

In 80's, compare with"enlighten literature", she broke the chain of left thought and the collectively recount of the new period literature. She carried out the triumph of individual to community by using enlightening aesthetic displacement. In 90's, Tie Ning constructed true literature on intellectual edge-guard stance."new-realistic novel"sink into puzzlement . She acquired brief balance of modernity recount; In new century,"new historical novel"slinked into the predicament of"the epic turn"in escaping"great narrative". Tie Ning constructed the intellectual modernity narrative by fusing daily life and enlighten narrative.

论文通过铁凝与新时期的&新启蒙文学&、&新写实小说&、&新历史小说&对比研究发现：在80年代，铁凝继承了鲁迅的&立人&思想，冲破了&极左&思想的束缚和新时期文学的&集体叙事&，以对启蒙理性的审美置换实现了个体对群体的穿越和超越；90年代铁凝以知识分子的&边缘和守卫&的姿态建构着真善美的文学，避免陷入&新写实小说&的理性主体的缺失和道德理想消解的审美现代性困境，获得现代性叙事的短暂平衡；新世纪，铁凝在启蒙叙事和日常生活叙事的完美融合中建构起崭新的知识分子现代性叙事，为后革命时期建构宏大叙事提供了思想资源和审美表达的借鉴。

The thesis think Tie Ning female identity experience poem ego, female ego, reasonableness ego of continuously mature development process,Tie Ning molded to take"fragrant snow" as to represent by poem of beautiful and artistic young girls, remeding the defent of female narration. After mid–80s, Tie Ning with mightiness of the female consciousness carried out to cross and surmount of the female's rightness by the female's review of ugly and appreciate beauty by duble variation. Which is the make–up of what Zhang Jie and Zhang Xin Xins novels neglect to female's essence life, It is also the watchful to Lin Bai and Chen Rans which excessively sinked in a female. In the new century, Tie Ning's stupid flower embody the tendency of the female return to the spirit of new time and great words, Indicate new century female literature is a important change of appreciate attitude.

论文认为，铁凝女性身份的认同经历了诗性自我、女性自我、理性自我的不断成熟的发展过程：铁凝以诗性自我塑造了以&香雪&为代表的美仑美奂的少女群像，弥补了新时期初期深陷男权文化中心的女性写作的匮乏；80年代中期以后，铁凝以强烈的女性自我意识在审丑与审美的双重变奏中实现了对女性自我的超越，既是对张洁、张辛欣们忽视女性本体生命欲求的弥补，也是对林白、陈染们过度陷于女性偏执的警醒；在新世纪，铁凝的《笨花》体现了女性意识叛逆后回归新的时代精神和宏大话语的趋向，预示了新世纪女性文学审美态度上的重大转变。
