To investigate the pollution levels, occurrence and distribution of estrogens, six estrogens in the surface sediments of Wenyuhe River were analyzed quantitatively by GC/MS following ultrasonicated extraction including diethylstilbestrol, estrone(E1),β-estradiol(E2), 17α-ethynylestradiol(EE2), estriol(E3), and β-estradiol 17-valerate. Six estrogen concentrations ranged from 0.39-36.6ng/g and the mean concentration was 10.2ng/g.

为了调查温榆河沉积物中雌激素物质的污染状况，采用超声萃取、GC/MS法研究了6种常用雌激素（包括己烯雌酚DES、雌酮E1、雌二醇E2、乙炔基雌二醇EE2、雌三醇E3和戊酸雌二醇EV）在北京温榆河上游及干流表层沉积物中的含量水平，并对其分布及来源情况进行了分析。

They have close relationship as the former may provide new ideas and approaches for the later, while the later may be the simulation for the former and gives it helps in degradation products identification and mechanism explanation. It is necessary to choose a suitable system, which has high potential of treating EDs and close relationship to the natural environment, to combine the researches in the two aspects. Our group has been engaged in researches on the photochemical properties and application to water pollution control of different ferric species including Fe -OH complexes, Fe -polycarboxylate complexes, Ferric oxides and Fe -humic acid complexes. Fe -oxalate complexes system has higher efficiency than the other ferric species systems in photooxidation and degradation of organic compounds. This thesis is focused on the photodegradation of nine EDs estradiol (E2), estrone (E1), 17α-ethynyl estradiol (EE2), diethylstilbestrol , bisphenol-A , 4-Nonylphenol , 4-Octylphenol , di-n-butyl phthalate , and di (2-ethylhexyl) phthalate .

因此从处理效率和环境化学意义两方面考虑，结合本课题组在不同铁形态（包括Fe-OH配合物、Fe-多羧酸配合物、Fe氧化物、Fe-腐殖酸配合物等）的光化学特性及其在水污染控制中的应用方面较系统的研究工作基础，本论文选择了四类共9种典型的内分泌干扰物（雌二醇（E2）、雌酮（E1）、17α-乙炔基雌二醇（EE2）己雌酚、双酚A、壬基酚、辛基酚、酞酸二丁酯和酞酸二乙基己基酯），研究了它们在Fe-草酸盐配合物体系中的光降解效果，推测其降解机理，探索环境内分泌干扰物光氧化处理的新体系，同时为预测其在环境中的光降解行为提供了依据。

So the oxidation of diethyl stilbestrol was that two phenolic hydroxyl groups were oxidated to carbonyl group by two electrons and two protons process.

所以己烯雌酚的氧化过程为两个酚羟基经过2质子2电子反应被氧化成羰基。

Results Three kinds of veterinary drugs (erramycin,tetracycline,stilboestrol)were detected in the raw meat.The detection rate of terramycin was 5.13%,and the detection rate of stilboestrol and tetracycline was 2.56% and exceeded the national standards.However,aureomycin and hydroxymethyl tertbutyladrenergics were not detected.

结果 共检测出3种兽药(土霉素、四环素和己烯雌酚)残留，金霉素和盐酸克伦特罗未检出；检出率分别为土霉素5.13%，四环素、己烯雌酚为2.56%；残留量均超出中国相应标准。

A method has been developed to determine residual stilbenes such as diethylstilbestrol, dienestrol and hexestrol in animal tissues using solid phase extraction and gas chromatography-mass spectrometry.

建立了动物组织中己烯雌酚、己二烯雌酚和己烷雌酚残留量的气相色谱-质谱分析方法。

With this aim, two different haptens mono- O -3-carboxypropyl- diethylstilbestrol and mono- O -carboxymethyldiethylstilbestrol with carboxylic group that preserve the molecular structure character of diethylstilbestrol were synthesized. The haptens were conjugated with the carrier proteins bovine serum albumin by mixed-anhydride method for immunogen and conjugated with ovalbumin by active ester method for coating antigen.

首先，两种保留己烯雌酚特征结构并具有活性基团的半抗原正丁酸己烯雌酚单醚、乙酸己烯雌酚单醚被合成；然后采用混合酸酐法将半抗原与BSA偶联制备成免疫原，采用活性酯法将办抗原与OVA偶联制备了包被原。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
