磷酸盐

The preconcentration, separation and purification of phosphate was the foundation of seawater phosphate δ^18O analysis.

海水中溶解态磷酸盐的富集、分离与纯化研究是测定海水磷酸盐氧同位素组成的基础。

It demonstrated that the molecular size matching and the sterically arrangement of groups of studied compounds with nucleoside phosphates are very important for the interaction of them. And the quenching ability depends on the interaction of these species strongly. Evidently, this phenomenon can be used as a method for the molecular recognition of nucleoside phosphate by the changing of fluorescence intensity of these compounds.

实验结果表明，分子尺寸的匹配和化合物中基团的空间合理排布是化合物和核苷磷酸盐间能发生相互作用的重要根据，而猝灭则强烈地依赖于这类物种间的相互作用，因此可利用化合物荧光强度的改变来识别各种不同的核苷磷酸盐。

In this method, boiling water was used to destroy the substances that induce the decomposition of polyphosphates. In order to remove the impurity, trichloromethane was used as the precipitator.

用沸水破坏使多聚磷酸盐分解的物质，并用三氯甲烷去除水产品中蛋白质等杂质，离子色谱准确测定多聚磷酸盐各组分的量。

It has also been found that acidic medium is necessary for the formation of protonated monomer and dimer. The stability of the dimer of the tungstophosphate is lower; a pure monomer can be obtained by treating the mixture with a base (Bu4NOR). However, the dimer of tungstosilicate is stable under the same condition.

实验结果还表明，酸性介质是生成质子化单体和二聚体的必要条件，且钨磷酸盐二聚体的稳定性较低，用碱(Bu4NOH)处理合成产物可得纯的钨磷酸盐单体，而相同条件下钨硅酸盐的二聚体却比较稳定。

In the past there has been a lot of emphasis on chromatin modifications and physical access to genes, but Scp1 regulates the activity of the enzyme that transcribes genes directly, he adds.

激酶可以为RNA聚合酶 II加上一个小的磷酸盐基团，使RNA聚合酶 II继续转录基因，而Scp1则会移除小的磷酸盐基团，使RNA聚合酶 II停工。

Methods:Spectrophotometry was selected to determine the phosphorus level in soya lecithin,based on the formation of the blue complex by phosphate with ammonium molybdate and Fiske-Subbarow reagent in acid solution.

将样品中的有机磷酸化合物分解转化为无机磷酸盐，再利用在酸性溶液中磷酸盐与钼酸铵及Fiske-Subbarow试剂作用生成蓝色的化合物，在660nm处用分光光度法测定。

It was established in 1988,mainly produces all kinds of phosphates,compound phosphate,citrates and other inorganic salt such as zinc salt,magnesium salt,iron salt etc.food additives,which have been further exported to some ten countries and regions of the U.S.A,Japan,Korea and countries in Europe and southeast Asia.

公司始建于1988年，专业从事磷酸盐、复合磷酸盐、柠檬酸盐及其它无机锌盐、镁盐、铁盐等食品添加剂的生产，产品广泛应用于食品、饮料、医药、牙膏、纺织、日化、陶瓷等行业，远销美国、欧洲、日本、韩国、东南亚等十多个国家和地区。

The relationship between separation factor a and concentration of phosphate buffers in eluant is investigated.

在YWG-R_4NCl阴离子交换柱上，用磷酸盐溶液梯度淋洗或乙醇-磷酸盐缓冲液作流动相分离了A，dA，AMP，dAMP，ADP，dADP，ATP和dATP。

Rare-earth doped borates(BO3),phosphates(PO4),vanadates(VO4), vanado-phosphate(YO4),borosilicate(LaBSiO5), and aluminate phosphors had been prepared by some different methods, such as high temperature solid state method, hydrothermal method, co-precipitation method and so on.

中文摘要：采用高温固相法、水热法、共沉淀法等不同方法制备了一系列掺稀土的稀土正硼酸盐BO3、正磷酸盐PO4，矾酸盐VO4，矾磷酸盐YO4和硼硅酸盐LaBSiO5及铝酸盐等荧光粉。

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
