烷基环己基苯甲酸的合成研究：主要研究了乙基环己基苯甲酸的合成，以乙酰氯、环己烯、苯为原料，三氯化铝为催化剂，合成乙酰基环己基苯，用水合肼、氢氧化钾、一缩二乙二醇经过高温加热还原羰基(Wolff-黄鸣龙还原)，将所得到的乙基环己基苯用乙酰氯进行傅克酰基化得到乙基环己基苯乙酮，所得中间体经过处理之后直接得到反式产物，将反式异构体的乙酰基氧化得到反式烷基环己基苯甲酸。

It was shown by further research that the formed tungsten oxide had an obvious layer-like structure, where from outer to inner layer the valence of tungsten increased and the reduction degree decreased. The carbonization of W depended on the replacement of W atom at the center of the body-centered cubic by C atom and the minor adjustment of C atom position and the lattice parameters.

深入研究表明，氧化钨碳还原颗粒具有明显的层状结构，自外到内钨的化合价递增，还原程度降低；钨的碳化是碳原子替换体心立方钨晶胞的中心钨原子，然后碳原子转换到钨原子点阵间隙再经晶胞常数微调而形成。

The results of cycle voltammetry experimentation in simulated environment medium and XRD test are that main oxidation process is harmful patina CuCl formation and reduction process is CuCl reduced or deoxidised to pure Cu.The reaction current is so high that severely damages to bronze substrate.

青铜在模拟环境介质中的循环伏安实验及XRD测试结果表明，氧化过程主要为生成有害锈CuCl的过程，还原过程主要为CuCl还原成纯铜晶粒的过程，并且反应电流较大，对青铜基体的破坏性较大。

The resistance to Cr and regeneration character of biological iron sulfide composites were studied. The composites consisted of sulfate reducing bacteria and nanosized iron sulfide produced by SRB. A new reduction-regeneration recirculation process for treating chromium-containing wastewater and reclaiming chromium was developed with the regeneration character of the composites.

研究了由硫酸盐还原菌与其原位生成的纳米硫铁化合物组成的生物硫铁复合材料的耐铬性能和再生性能，并利用其再生特性，设计了处理高浓度含铬废水及铬资源化的还原－再生循环处理工艺。

It was found that tignite and its char have their NO re d uction efficiency higher than those of other coals and chars.The content of vola tile in coals,surface area of the chars and the content of metal catalyst in ash are all important factors affecting the NO reduction efficiency.

实验结果表明，褐煤及褐煤焦对NO的还原能力明显强于烟煤和烟煤焦，煤粉挥发分含量、煤焦颗粒的比表面积和煤灰中的金属氧化物含量都对NO还原有重要的影响。

Drugs of beta-hydroxy-beta-methylglutaryl coenzyme A reductase inhibitors family are usually used as a very effective lipid-lowering preparations but they simultaneously block biosynthesis of both cholesterol and ubiquinone Q10, which is an intermediate electron carrier in the mitochondrial respiratory chain. It is known that reduced form of ubiquinone Q10 acts in the human LDL as very effective natural antioxidant.

HMG-CoA还原酶抑制剂是非常有效的降脂药物，但它同时抑制胆固醇和辅酶Q的生物合成，而其中辅酶Q是线粒体呼吸链中的中间电子载体，其还原形式在人LDL中是有效的天然抗氧化剂。

The reductive hydrogenation of sterols is stronger downward with the depth,and that is much stronger in Site 8 than in Site 17 due to the different sedimentary circumstances.

随着沉积深度的增加，甾烯醇的加氢还原作用越强，且由于两个站位不同的沉积环境，8站位甾烯醇的加氢还原作用更强。

When surface of TiO2 powder is enveloped by carbon, the reduction is mainly solid-solid reaction between carbon and titanic oxide.

结果表明钛氧化物的还原是逐级进行的，反应过程伴随着相变，当TiO2粉末和C粉末均匀混合时还原碳化反应主要依赖于CO／CO2传质的气固反应，当TiO2颗粒表面被C包膜时主要是碳和钛氧化物之间的固固反应，当TiO2粉末和C粉末混合压球时则两种反应机理均有。

REE geochemical characteristics and their systematic changes in the sedimentary section suggest that there existed a process of ingression-regression in this area in the early Cambrian period. The black shale series resulted from the mixing between normal seawater sediments and hot seawater sediments and were deposited under the transitional condition from reduction to semi-reduction and weak oxidation in a shallow-sea clinoform zone of a relatively deep sea environment with dry climate.

稀土元素地球化学特征反映该区早寒武世曾发生过一次明显的海侵-海退过程，黑色岩系为正常海水与热水混合沉积的产物，形成于缺氧还原状态过渡到半还原-弱氧化状态的过程中，沉积环境为干燥气候条件下相对较深的浅海斜坡环境。

Consequently,it is possible to discriminate the tectonic setting of ore-forming and rock-forming by studying major elements of sandstones in Dayao sandstone copper mine.

大姚砂岩铜矿成矿受氧化-还原环境控制，分析大姚六苴矿床岩石和矿石样品的F e2+/F e3+值与铜元素含量之间的关系，探讨砂岩铜矿的氧化-还原环境特征，从而建立大姚砂岩铜矿的地球化学相。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
