The activated Br - and Cl - is released and it will forms HBrO and HClO in further when we put the bormochloro hydantoin in the water, and thus the HBrO and HClO will oxidate the enzymes such as a enzymes with SH so as to sterilize and purify the polluted air.

采用溴氯海因消毒剂在水中能够通过不断释放出活性 Br -和 Cl -，形成次溴酸和次氯酸，将微生物体内的生物酶氧化而达到杀菌的目的。

Results:Keep the hyoscine butylbromide peak separate from the related substances and determine the limit of the main i mpurity.

结果：丁溴东莨菪碱与其他莨菪碱峰完全分离，从而对主要的杂质氢溴酸东莨菪碱进行了限量检查。

The effect of various conditions on the reaction, such as solvent, temperature, the amount of catalyst, the concentration of hydrobromic acid, oxygen/air and so on, was studied.

在此基础上，系统地考察了溶剂、温度、催化剂用量、氢溴酸的浓度、氧气/空气等因素对芳香化合物氧化溴化反应的影响。

Methods The mercury in urine, which is the total amount of inorganic mercury in urine, including those produced from organic mercury after treated by potassium bromate and potassium bromide, is determined by atomic absorption spectrophotometer after reduction into mercury atom with sodium borohydride.

方法］尿样中汞（尿中无机汞和经溴酸钾－溴化钾处理尿中有机汞生成的无机汞之和）以硼氢化钠还原生成汞原子蒸气，用原子吸收光谱仪测定其汞的含量。

The method is based on the catalytic effect of NO~-_2 on oxidation of bromophenol red by potassium bromate in H_3PO_4 mediun.

以质量分数为48%的氢溴酸水溶液、仲丁醇为反应原料，浓硫酸为催化剂合成仲溴丁烷，考察了反应原料和催化剂用量以及反应时间对产率的影响。

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。
