起始原料取代的环己基苯甲酸由取代的苯乙酮经溴仿反应得到。

The bromoform concentration of 16.4 μg/l measured after 80 min contact time was reduced to 1.6 μg /l by GAC filtration with an empty bed contact time of 4.2 min.

接触80分钟后测出的16.4μg/l的溴仿浓度经过4.2分钟空床停留时间的活性炭过滤已降至1.6μg/l。

This paper also reports the fusion curves of carbon tetrachloride, chloroform, bromoform, silicon tetrachloride, benzene, nitrobenzene, bromobenzene and chlorobenzene at pressures up to 3500 MPa between 226 K and 915 K.

本论文还讨论了四氯化碳、氯仿、溴仿、四氯化硅、苯、氯苯、溴苯和硝基苯八种纯物质的熔点曲线，温度范围为226 K到915 K，压力最高为3500 MPa。

The reduction of trihalomethane formation potential was discussed, which indicated that ozonation has a good removal for chlorofom and bromodichloromethane formation potential, but for dibromochloromethane formation potential the removal efficiency was undesirable and there was almost no removal for bromoform forming potential, Furthermore, when there was enough bromide in water, ozonation would have a promotion effect for bromoform formation potential.

通过研究臭氧对三卤甲烷生成潜能的去除规律发现，臭氧对三氯甲烷和二氯一溴甲烷生成潜能都有很好的去除，对一氯二溴甲烷生成潜能的去除效果较差，对溴仿生成潜能基本没有去除。当水中溴化物含量较高时臭氧对溴仿的生成反而具有促进作用。

However, the surplus residual chlorine can affect people's taste and smell, destroy the quality of water. Moreover, in the process of disinfection, chlorine can react with organic matter and produce a series of hydrochloric ether such as chloroform, bromoform, bromodichloromethane, chlorodibromomethane and so on, these matters can cause to some extent cancer to human body.

但是，水中过量的余氯会影响水的口感和气味，破坏水的品质；此外，在消毒过程中，氯与水中残余的有机物产生化学作用，生成一系列氯代烃如三氯甲烷、溴仿、溴二氯甲烷、氯二溴甲烷等，这些物质会对人体产生一定程度的致癌作用；对于以自然水源作为生活用水来源的城市必然要对水加氯消毒后才可使用。

We gained the ethynylferrocene in high yield by the the reaction of triphenylphosphine with chloroform or bromoform in the presence of KOBu~t to give witting reagent, which reacted with formylferrocene and then followed by n-butyllithium dehydrohalogenation.

在本论文的第二部分，我们用三苯基磷与溴仿或氯仿在叔丁醇钾作用下，制得三苯基磷甲叉烯，然后与二茂铁甲醛反应，得到二氯取代烯烃，在正丁基锂作用下得到二茂铁乙炔。

Using the technique of ultraviolet absorption spectrometry and fluorescence spectrometry, this study examined the interactions between bromoform(CHBr3) and calf thymus DNA with or without Cu2+, Co2+, Cd2+ and Mg2+individually or concurrently.

采用紫外光谱和荧光光谱法研究了CHBr3与离体小牛胸腺DNA间的相互作用，以及Cu2+、Co2+、Cd2+、Mg2+ 4种金属离子单独或共存时对CHBr3与ctDNA结合的影响。

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.
