查询词典 FE

Studied the coordination chemical reaction of Fe、Co、Ni、Cu、Mg、Ca、Al with TC,OTC,CTC and the ternary association of Co-OTC、Ni-CTC with DAN,we found that the formation of new compounds improved significantly the hydrophilic properties of TCs,the TCs are transformed into hydrophobe from hydrophilic matter.

2研究了Fe、Co、Ni、Cu、Mg、Ca、Al与TC、OTC、CTC之间的配位化学反应和Co-OTC、Ni-CTC与DAN之间的三元缔合作用，发现新化合物的形成显著改善了TC、OTC、CTC的亲水性能，使其由亲水物质转变为疏水物质，有利于提高亲水有机溶剂气浮浮选体系对水样中痕量四环素类抗生素的测定灵敏度和分离/富集效率。

It is for the first time found that the liquid hypoeutectic Al-Fe alloy has a critical temperature of 920℃ in the curve of the cluster size to temperature. Below 920℃ the structural change is predominantly in the medium-range order, while in the short-range order above 920℃.

首次发现，亚共晶Al-Fe合金熔体的原子团簇尺寸等在920℃左右存在明显的变化。920℃以下熔体结构的变化以原子团簇尺寸即中程尺度参数的变化为主，而920℃以上则以配位数等短程序参数的变化为主。

The observation under microscope, the analysis of Au. Ag. Cu. Fe. As content by electron probe and the micrograph of gold grains, confirm that placer gold are natural Au-Ag alloys. The structure and chemical compositions of verge and interior of gold grains differ significantly for large grains but little for small grains and those which intergrow with guartz and limonite.

镜下观察、电子探针分析(Au、Ag、Cu、Fe、As含量)及显微照相等研究，证实了砂金是天然Au-Ag合金，其边部与内部的结构、成分具有不均一性，这在中粗粒金中表现尤为明显，而细粒金及带连生体的金常常不具备这一特点。

用FTIR、TG-DTA、XRD等对产物形成过程及结晶学特征进行了研究，考察了合成样品与Sm0.2Ce0.8O1.9的化学相容性；利用碘滴定法测定了该系列产物中Fe元素的平均表观化合价和氧的非化学计量值。

The corrosion-inhibiting efficiencies of isoquinoline and its hydroxyl and carboxyl derivatives on Fe electrode in HCl solution have been determine with electrochem.

本文在30℃， 1.0mol.dm^-3 HCl溶液中用电化学方法测定了异喹啉及其羟基，羧基衍生物对Fe电极的缓蚀效率。

The equation ofextraction reaction has been deduced through a study on the equilibrium as Fe~(3+)+ H~++ 4Cl~-+ 3S Kex ?

萃取平衡的研究表明N503萃取铁的反应为：Fe~(3+)+H~++4Cl~-+3S？

It remains disputable that birds can obtain geomagnetic information for homing because otoliths in the lagena are rich in elements Fe and Zn.

有人认为瓶状囊的耳石中Fe、Zn等元素含量较高，使得鸟类能够感受地球磁场而具有导航能力，但这个假说目前还存在争议。

The macula lagena is innervated and has neural projections to the brainstem, but its physiological function is still unclear. It remains disputable that it is because otoliths in the lagena are rich in elements Fe and Zn that birds can obtain geomagnetic information for homing.

有人认为瓶状囊的耳石中Fe、Zn等元素含量较高，使得鸟类能够感受地球磁场而具有导航能力，但对于这个假说目前还存在争议。

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.
