酚的

The influence of acrylic acid and cetane alcohol,amount of catalyst and inhibitor,reaction temperature,reaction time were investigated.

实验结果表明，合成的最佳反应条件为：丙烯酸与十六酯的物质的量之比为1.2∶1，对甲苯磺酸的用量为0.6%，对苯二酚的用量为0.4%，反应温度为110℃，反应时间为5 h。

Therefore, trying to use nitrogen protection or in the condition of low temperature in the process of comminution are recommended, which can provide more reliable results than that in the air.

因此，建议在植物多酚的测定过程中，尽量采用氮气保护的方式，或者在低温的环境中进行，从而使测定的结果更加接近植物内的真实含量。

SERS labelled immunogold was then used as probe to detect the interaction between the Goat anti-rat IgG and silver substrate (which we will use it as the substrate for solid antibody). It is found from experiment that SERS labelled immunogold can be non-specifically adsorbed onto silver surface uniformly because of the strong interaction between the protein molecule and silver.

由于我们设想以银片为免疫检测中固相抗体的基底，所以论文中首先以SERS标记的免疫金溶胶为探针，讨论了抗体与银表面间的作用，实验中发现，SERS标记的免疫金溶胶可以通过抗体与银之间的作用较好的自组装于银表面，同时，银表面上可以测到很强的苯硫酚的SERS信号。

This is because the tea is warm in the long term under the conditions of production, not only taste different from other tea, tea in an important matter,"polyphenols" the degree of oxidation is relatively high, so a large amount of oxidation products can be played stomachic effect.

这是由于普洱茶是在长期温热的条件下生产的，不仅味道与其他的茶不同，茶叶中一种重要的物质"多酚"的氧化程度也比较高，因此能产生大量氧化产物，起到健胃的功效。

Ecological conditions in such a mutation has occurred has become a unique shape of the genetic characteristics of the bleaching with the law back to the green phenomenon and the characteristics of ammonia Glandless.

在这样的生态条件下发生的突变体形成了独有的遗传特性，具有规律性的白化返绿现象和高氨低酚的特征。

In background information in the new JAFC paper, the health benefits of polyphenols are predominantly determined by their bioavailability, but this "is still poorly known", said Raika Koli and her co-workers from the Finnish National Institute for Health and Welfare.

在新的 JAFC 文件的背景信息中，多酚的功效依据生物利用度进行检测。但了解还很少。来自芬兰国立健康和福利学会的 Raika Koli 和她的合作者表示。

The final products were analyzed using UV-vis absorption spectrometry and GC-MS and the occurrence of nitronaphthalene and nitronaphthol will possibly deteriorate the environmental quality.

以稳态UV-vis吸收光谱及GC-MS分析了355nm光照HNO2+萘水溶液的最终产物，其中硝基萘及硝基萘酚的产生会恶化环境质量；联系瞬态研究结果，分析了所有产物的生成途径；确定了中间产物亚硝基萘对激光闪光光解实验的影响并提出了其在355nm光照下的解离机理。

"Tea and cocoa products account for the major proportion of total polyphenol intake in Western countries," the authors write.

&茶和可可产品占了很大比例的总多酚的摄入量，在西方国家，&研究报告的作者写的。

The synthesization technics of MPEG- MAA was studied in this paper,which is an important intermediate used for preparation of polycarboxylate superplasticizer.

本文对制备聚羧酸系减水剂的重要中间体——甲基丙烯酸聚乙二醇单甲醚酯的合成工艺进行了研究，考察了反应时间、催化剂对甲苯磺酸的用量、阻聚剂对苯二酚的用量、反应温度及甲基丙烯酸与聚乙二醇单甲醚的用量比对酯化率的影响。

As result, ten constituents have been detected in the blood after oral administration of Liu Wei Di Huang Wan, Compound I exists originally in Radix Rehmanniae, in blood it also derived from Fructus Coris and Rhizoma Alismatis; compound II ,IV and V belong to Fructus Corni, and compound VI and X are from Cortex Moutans, compoundIII, VII ,VIII and IX are the metabolites of Paeonol contained in Cortex Moutan.

然后，通过对六味地黄丸、六味地黄丸缺味成药及单味药对照样品的血中行为进行比较，确定了血中移行成分的来源。在认定的10个血中移行成分中，化合物Ⅰ由熟地、山茱萸和泽泻三个生药共同产生，化合物Ⅱ、Ⅳ、Ⅴ为山茱萸所含成分直接入血而形成，化合物Ⅵ、Ⅹ为牡丹皮所含成分直接入血而形成，化合物Ⅲ、Ⅶ、Ⅷ、Ⅸ为牡丹皮入血成分丹皮酚的代谢产物。

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。

Cell morphology of bacterial ghost of Pasteurella multocida was observed by scanning electron microscopy and inactivation ratio was estimated by CFU analysi.
