Two main factors made it,one is the nuclear hydroxyl number,another is the acid radical ionization degree.

极性主要由两个因素决定，一个是核的羟基数目，另一个是酸根的离子化程度。

Large amount of acid radical ion of acid salt can coexist or not in the solution depends on whether they have proton transfer reaction.

一般酸式酸根离子在溶液中能否大量共存，主要看它们之间能否发生质子转移反应。

The structure of ArsA ATPase with its ligand, arsenite, either on membranes or in solution, was revealed. The current trimeric ring-like structure of this protein doubts the previous dimeric model and gives deeper insight on this protein's physiological roles.

对亚砷酸根复合体ArsA蛋白质分子结构的揭示显示了该蛋白在亚砷酸根存在情况下，在膜上和水溶液中都是环形三聚体，对前人的二聚体模型假说提出了置疑，并为解释它的生理功能提供了重要的结构信息。

In compound 1, Co is in a distorted octahedron environment with four nitro-gen atoms from the tripodal ligand and two oxygen atoms from the bridged oxalate, and the molecule is a dimmer-ic structure consisting of two LCo unites linked by bridging oxalate.

在配合物1中，Co与来自三脚架配体的4个氮和草酸根桥联配体的2个氧原子配位，处于扭曲八面体配位环境。由草酸根桥联两套LCo，构成了一个双核结构。

It was found that the central metal ion is located at the symmetric center of the molecule. Four oxygen atoms from two H2O molecules and two 〔C6H4(CO2)2〕2- groups are coordinated with copper ion to form a similar planar square coordination configuration. There is one only unidentate coordination bond between O(1) in 〔C6H4(CO2)2〕2- and Cu2+.

结构分析发现，中心金属离子位于分子的对称中心位置，铜离子与来自2个水分子和2个邻苯二甲酸根中的4个氧原子形成近似正方形平面配位，邻苯二甲酸根是以1个O(1)与Cu2+离子形成单齿配体，O(2)和Cu2+之间没有形成配位键。

The results indicate that the formation of clustering of aluminates in solution,and the clusters are stabilized by sodium ions.

结果表明：Al_4~-单体形成的&分子簇&有利于聚合铝酸根分子的形成，Na~+控制聚合铝酸根分子的稳定存在，从而影响铝酸钠溶液中Al_3的析出。

A kinetic spectrophotometric method for the determination of trace oxalate was established, based on its inhibitory effect on the catalytic oxidation of indigo carmine with potassium bromate in the presence of V in 5 mmol/L H3PO4 media.

基于在5mmol/L磷酸介质中，草酸根对钒催化溴酸钾氧化靛蓝胭脂红褪色反应的抑制作用，建立了一种阻抑动力学光度法测定微量草酸根的新方法。

The addition order of arsenate and chromate influences their uptakes to a certain extent, especially on the surface of hydroxy-Fe-montmorillonite complex.

竞争吸附实验的砷酸根、铬酸根吸附量均高于对其单阴离子的吸附量，此现象在复合体表面最为明显，说明复合体具有独特的阴离子吸附性能。

The electrode doped with phthalocyanine tiv displays fast response time and high selectivity for salicylate over common anions. The resulting electrode has been successfully used for determination of salicylate in pharmaceutical preprations and urine samples.

以锡酞菁为载体，制得了性能优良的水杨酸根离子选择电极，电极对水杨酸根有较高的选择性及较短的响应时间，并实际应用于药物及尿样的分析。

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。
