酸根

Sol–gel/diaminobenzoic acid hybrid materials were also generated to be used as the MALDI matrices for the analysis of oligonucleotides. It is because that DABAs have good molar absorptivity at wavelength of 337 nm. Furthermore, two amino functional groups attached to the aromatic ring in DABAs can also suppress the cation adductions of oligonucleotides and leave the protons to the oligonucleotides during MALDI-MS analysis. This matrix system can be used as an alternative for the analysis of oligonucleotides.

本论文也利用双胺基苯甲酸与溶胶凝胶混成产物当做MALDI基质来分析DNA分子，利用双胺基苯甲酸本身具有吸收雷射的特性，且其含胺之官能基可和钠、钾离子竞争DNA上磷酸根的负离子结合部位，因此可和DNA有较强的亲合力，而在脱附游离的过程中并可转移质子给磷酸根，可有效降低盐类的干扰，此一基质系统可取代传统MALDI基质混合胺盐的效果，适合用於DNA样品的分析。

Kathon EDC 1.5% or other liquid biocide one time, silver nitrate (AgNO3) the next.

The binding molecular mechanism of R,R-SA-Pt and DNA was investigated by 13CNMR and DNA viscosity titrations.

结果：发现环方铂是通过方酸根的离去与DNA碱基之间形成共价键而结合的，而环斑铂是通过嵌插到DNA碱基对之间以非共价方式与DNA结合的。

Vegetable's roots absorb NO3(superscript -) mainly by the way of active absorption. Under retro-electrochemical gradient (170-250mv), NO3(superscript -) is absorbed into the interior of root through symplast in a state of ion.

蔬菜根系以主动吸收为主的方式吸收稍酸根离子，在逆电化学势梯度(170~250mv)下，硝酸根离子以离子态通过共质体途径进入根部内部。

The procedure is based on the inhibiting effect of ascorbic acid on the enhancing effect of oxalate on the potassium dichromate-potassium iodide／rhodamine6G system.

基于在硫酸介质中，抗坏血酸对草酸根加速重铬酸钾－碘化钾/罗丹明6G这一反应体系具有抑制作用，建立了动力学抑制光度法测定抗坏血酸的新方法。

Surprisingly, when the reaction temperature for the dianion formation is kept at 0-5

出乎意料，当反应温度为酸根形成保持在0-5

The Barium Carbonate process of removing sulfate ion from refined brine is briefly introduced and applied to the caustic soda devices at the Chlor-Alkali Plant of Shenyang Chemical Industry Co.

根据沈阳化工股份有限公司烧碱装置的实际状况，结合国内外脱除盐水中硫酸根的几种方法进行比较分析，简要介绍了碳酸钡法脱硫酸根技术及其在该公司氯碱分厂的应用情况。

Two new kinds of fluorocarbon phospholipids with choline and phosphate as polar head group were synthesized.

合成了两种具有氟碳疏水性链的磷脂，其极性部分分别为胆碱和磷酸根。

Thermodynamic analysis of cobalt removing process was carried out according to electrode potential theory and Nernst equation and proves that the removal of Fe(superscript 2+), Mn(superscript 2+), Co(superscript 2+) impurities in the solution is possible through oxidization by potassium permanganate to reduce the concentration level requested by industrial production, but not applied to Ni(superscript 2+).

用电极电势理论和能斯特方程对此除钴过程进行了热力学分析，结果表明：高锰酸根的氧化对溶液中杂质Fe(上标 2+)、Mn(上标 2+)、Co(上标 2+)的去除是可行的，可以达到工业生产对杂质的浓度要求；对于Ni(上标 2+)只能进行部分氧化。

An ate complex is a salt formed by reaction of a Lewis acid with a base whereby the central atom increases its valence.

酸根型配合物是指路易斯酸與特定的鹼生成的中心原子價升高的鹽。

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。
