使分离

Methods Streptomycin and dihydrostreptomycin were extracted from honey samples using a liquid extraction with a phosphate buffer followed by a solid-phase extraction based on weak cation-exchange columns. After sample preparation, the hydrophilic interaction chromatography was used to retain streptomycin and dihydrostreptomycin on the column for the separation of the analytes from endogenous compounds. The aminoglycosides were detected and quantified with electrospray ionization tandem mass spectrometry.

方法用磷酸盐缓冲溶液提取蜂蜜中的链霉素和双氢链霉素后，经弱阳离子交换柱进行固相萃取，样品制备后采用亲水作用色谱，使链霉素和双氢链霉素实现保留，从而与内源性物质达到分离，采用电喷雾离子化串联质谱法检测和定量。

Our place as a recognized world leader in power conversion has been built up over the years with contributions of business units from industry majors including General Electric Company in the UK, Allgemeine Elektrizitats Gesellschaft in Germany and Westinghouse Drive Systems in the US, as well as Compagnie Generale d'Electricite, then Cegelec and ALSTOM in France.

通过与英国通用电气公司，德国通用电气公司，美国通用电气公司，美国的西屋电气驱动系统，法国的西技来克和阿尔斯通的收购，合并和分离使我们成为电能转换和控制领域毫无疑问的领导者。科孚德正以全新的形象迎接新的挑战。

A method for simultaneous determination of oxytetracycline, tetracycline, chlortetracycline and choramphenicol in seafood was successfully developed using high performance liquid chromatography with ammonium acetate/water and acetonitrile as the mobile phase. The results showed that the four antibiotics were well separated under the optimum conditions, with the limits of detection being 32 μg/kg for oxytetracycline, 15 μg/kg for tetracycline, 23 μg/kg for chlortetracycline, and 19 μg/kg for choramphenicol. The recovery of standard additions was 76~92% and the relative standard deviation was 0.8-4.5%. The method is rapid, sensitive, accurate and reliable and can be applied in the analysis of antibiotic residues in seafood.

建立了同时检测海产品中土霉素、四环素、金霉素、氯霉素残留的高效液相色谱分析方法，以醋酸铵-醋酸/水缓冲液和乙腈作为流动相，通过二元梯度洗脱，使四种抗生素获得了较好的分离，以基线噪音的3倍计算，土霉素、四环素、金霉素、氯霉素最低检出浓度分别为32μg/kg、15μg/kg、23μg/kg、19μg/kg，在添加浓度范围内，四种抗生素的加标回收率为76~92%，相对标准偏差为0.8~4.5%，该方法快速、灵敏、准确，可靠性高，可用于海产品中抗生素残留的色谱分析。

Good sense which kept him clear of Brook Farm because he thought Fourier "had skipped no fact but one, namely life," kept him clear from many similar departures into matters which the twenty-first century will probably not remember.

这种好的意识让他与&小溪农场&分离开来，因为他认为傅立叶的理论&只有生命才能脱离现实&使他的哲学理论逃离了那些将在21世纪将无人记得的问题。

The whole point of learning to project is to get your astral body to separate from the physical while fully conscious.

学习投射的关键是，有意识地使你的星体躯体与肉身分离。

I'm strongly against the death penalty — it's an eye for an eye.

我不赞成死刑——这是以牙还牙的报复行为。

And to get you the support you need, we're enlisting all elements of our national power: our diplomacy and development, our economic might and our moral suasion, so that you and the rest of our military do not bear the burden of our security alone.

并给你们所须的支援，我们正徵召国家所有各种的力量：我们的外交及发展，我们的经济力量与道德劝说，所以你们与其他军人不须要孤独地负起国家安全的责任。
