溴仿

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。

Macerate 1.0g of the powdered sample with 20.0 ml of chloroform plus 0.3ml of 25％ NH_4 OH in a glassstoppered flask overnight.

本文报道用不含粘合剂的氧化铝薄层，以二甲苯-丙酮-无水乙醇-二乙胺(50：40：10：0.6)为展开剂分离茄科植物中的莨菪碱、东莨菪碱、山莨菪碱、樟柳碱及红古豆碱等五种莨菪烷生物碱，用改良Dragendorff试剂-Wagner试剂(1：1)显色，定量收集莨菪碱、东莨菪碱及山莨菪碱的斑点，莨菪碱和东莨菪碱用氨甲醇洗脱，蒸干洗脱液后分别用pH 5.6及pH 4.5的溴甲酚绿溶液作比色测定；山莨菪碱用4％醋酐氯仿洗脱，蒸干洗脱液后用pH 5.6的溴甲酚绿溶液作比色测定。

Moreover, evaluating the effects of different factors such as laying up unaffectedly, temperature.

此外，又评价了自然放置不同时间和不同温度对自来水中氯仿、三氯乙烯、二溴一氯甲烷等存在的影响。

MethodsThe content was determined by solvent extraction and acid dye colorimetiy, with Acanthoine Ruscope-ine （C16H22N4O2） as a control criterion and bromocresol green as the acid dye, and the wavelength was at 418 nm.

方法采用溶剂萃取酸性染料比色法测定，以去氢飞廉碱（C16H22N4O2）为对照品，溴甲酚绿为酸性染料，用氯仿萃取，检测波长418 nm。

Methods:total alkaloids of radix Sophora lavescens were extracted by acidified water,then adjusted to neutral by sodium hydroxide solution, dissolved with buffer solution,then were mixed with 0.025％ of bromothymol solution and chloroform,and then the mixture was shaken,standing and demixed,the absorbability of chloroform layer was detected at the wavelength of 413nm.

将苦参的酸水提取液用氢氧化钠溶液调节至中性后，依次加入pH=7.6缓冲溶液，溴代麝香草酚蓝指示液、氯仿混合振摇，静置分层，于413 nm波长处测定氯仿层吸收度。

Results Inbreathe and dermal exposure to THMs in reclaimed water were the main ways of exposure for occupational worker and general populations in road clearing and public garden virescence in Beijing.

结果 再生水中氯仿、一溴二氯甲烷、二溴一氯甲烷、三溴甲烷的浓度分别为0.875~108、0.06~11.0、未检出～5.82、未检出～3.04μg/L。再生水回用于道路压尘、公园绿化，人群通过吸人和皮肤两种途径暴露于再生水，吸人暴露为主要途径，其消毒副产物THMS中。

For the bargellini reaction, acetone and chloroform was used instead of a--bromobutyrate to cut the cost.

同时，以丙酮和氯仿代替a-溴代异丁酸酯，显著降低生产成本。

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。
