查询词典 bromothymol

The proposed method involves forming coloured ion-pair from ephedrine hydrochloride and bromothymol blue at pH 6.5 extracting the ion -pair thus into chloroform and measuring the absorbance chloroform solution at 414 nm.

根据盐酸麻黄碱在一定pH条件下，可与溴麝香草酚蓝反应生成稳定的络合物这一特性，选择414nm波长处测定其含量。

The conclution is confiemed mutually by the tested result of TBAB distribution coefficients in the differen phases in Benzene/TBAB/water/KBr system,the distribution coefficients is tested by the method of Bromothymol Blue Spectrophotometric Determination.

得到结论同溴百里酚蓝分光光度法测定苯/TBAB/水/KBr体系各相态中TBAB分配系数的结果相互验证。

A bacterial strain ADZ1 that demonstrated higher efficient in the aerobic denitrification was isolated from the sewage of urban rivers on the selective medium, Bromothymol Blue, after enriched in the shaking flasks. The reduction efficiency for nitrate and the total nitrogen reached 93.1% and 34.7% within 48 hours respectively. Sequence of 16S rRNA suggested that strain ADZ1 belongs to the genus of Pseudamonas, and further was identified as Pseudomonas putida by VITE K?

采用富集培养和BTB平板法从城市河道污水中筛选、分离获得了一株高效的好氧反硝化菌株ADZ1， 48 h内对硝酸盐的降解率为93.1%，总氮的去除率为34.7%。16S rRNA测序及系统发育分析结果表明该菌株属于Pseudamonas sp。，经VITEK？

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。

Surface seawater samples are pumped into a PVC tube enclosing an inner Teflon AF tube, which served as a long pathlength gas-permeable liquid-core waveguide for spectrophotometry. The Teflon cell contains a pH sensitive indicator-buffer solution consisting of bromothymol blue and sodium carbonate.

该传感器采用Teflon AF 2400液芯波导管作为C02选择透过性膜，该液芯波导管同时也是传感器的比色池，我们采用溴百里酚蓝和碳酸钠(Na_2CO_3)溶液为主要成份的pH敏感指示剂作为缓冲溶液。

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。
