酸根

The blue-violet range, while ascorbic acid, dehydroascorbic acid and hexacyanoferrate are

抗坏血酸和氰合铁酸根是无色的。因此对[Fe6]3-进光谱测定时它们是会造成干扰的。

Urea and amide were used as guest molecule in the chapter 2. Dicarboxylate 36 shows three anodic waves and two cathodic waves in CV. The cathodic current decreased when urea and amide were added.

第二部分则是将尿素与醯胺基团当成被侦测的客分子，我们合成了具双酸根的三苯胺衍生物盐类36，发现尿素与醯胺基团加入后盐类36的循环伏安谱之还原电流减少可以用来侦测尿素与醯胺基团。

Recently, study on ion-selective electrodes with anti-Hofmeister selectivity pattern is an important and interesting project in the fields of electrochemistry and electroanalytical chemistry.

研究发现，以呋喃甲醛甘氨酸合铜为载体的电极对水杨酸根离子有高的选择性并呈现出反Hofmeister选择序列行为。

We found that under acid condition, selenite radical combined with active hydroxide radical and amino-group of chitooligosaccharides to form chitooligosaccharides - Se compound molecule, the remaining group complex interacted with the negative sodium tripolyphosphate via electrostatical interactation to form nanoparticles with the size about 100nm.

通过透射电镜、粒径分析仪等方法表征，发现壳寡糖-硒纳米颗粒平均粒径为100nm左右，在酸性条件下，亚硒酸根与壳寡糖单元上活性羟基和氨基化合，形成壳寡糖-硒复合分子，剩余的基团与带负电的多聚磷酸钠复凝聚，在4℃下能够稳定保存，25℃以上壳寡糖溶胀而致纳米颗粒发生分解。

The results show that:(1) When N-methylethylenediamine and N, N'-methylethylenediamine equatorially coordinated to Cd〓, arenedisulfonates such as 1, 5-naphthalenedisulfonate, 2, 6-naphthalenedisulfonate and 4, 4'-bipenyldisulfonate act as a bridging ligands coordinated to adjacent Cd〓 centers, leading to a one dimensional chain structure.

研究结果表明：（1）N-甲基乙二胺和N，N'-二甲基乙二胺与Cd〓在赤道平面配位后，芳烃二磺酸根离子作为桥联配体与相邻的Cd〓在轴向配位形成了一维链状结构。

The results show that:(1) When Cu〓 equatorially coordinated by four nitrogen atoms from amine ligands such as ethylenediamine, N-methylethylenediamine, 1, 2-diaminopropane and 1, 4, 8, 11-tetraazacyclotetradecane, etc., Cu〓 could be axially coordinated by oxygen atoms of-SO〓 group.

研究结果表明：（1）当Cu〓在赤道平面与来自胺配体（如乙二胺、N-甲基乙二胺、1，2-丙二胺和1，4，8，11-四氮杂环十四癸烷等）的四个氮原子配位后，在轴向则可以与来自磺酸根离子的-SO〓基团氧原子配位。

When Ni〓 was equatorially coordinated by four nitrogen atoms from the same amine ligands such as ethylenediamine and N-methylethylenediamine, arenedisulfonates did not axially coordinated to Ni〓.

Ni〓与同样的胺配体（如乙二胺、N-甲基乙二胺）的四个氮原子在赤道平面配位后，芳烃二磺酸根离子并没有在轴向与Ni〓配位，水分子仍然占据轴向的位置。

Phytate and phosphate were determined within 15 min, and no interference was found in the presence of fluorate, chlorate, nitrate, sulphate and TCA.

实验结果表明，植酸根与磷酸根的检测不受F-、Cl-、SO2-4、NO-3、CC l3CO-2等阴离子的干扰。

A novel supramolecular complex, [Cu2]CH3OHH2O (fum=fumarate dianion, dpphen=4, 7-diphenyl-1, 10-phenanthroline), has been prepared from the reaction of bidentate ligand, fumarate with CuCl2, and were characterized by element analysis, IR, thermal analysis and X-ray diffraction technique.

利用螯合配体4，7-二苯基－1，10-邻菲罗啉与反丁烯二酸钠及铜盐反应合成了一种新型超分子配合物[Cu2]CH3OHH2O（fum=反丁烯二酸根，dpphen=4，7-二苯基－1，10-邻菲罗啉）。通过元素分析、红外光谱、热分析和X射线单晶衍射等技术对其进行了表征。

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。
