We had determined the reducing power of the three Boletes,in addition,the antioxidant effect on peroxidation of unsaturated fatty acid in lipoprotein,Fenton system and the self oxidation method of pyrogallol were measured in vitro,we also detected the compounds of antioxidant.

实验测定了三种牛肝菌甲醇提取物的还原力，以及在卵黄脂蛋白不饱和脂肪酸过氧化体系、Fenton体系和邻苯三酚自氧化体系中的体外抗氧化活性及其起抗氧化作用的物质。

I say "virtually all manufacturers" because there is one, but only one, company that provides "self-preserving" skin- and hair-care products---products that are formulated without added preservatives such as parabens and formaldehyde.

我说"差不多所有的生产厂家"因为这里有一家，而且是唯一的一家，提供采用了"自保技术"的皮肤和头发的护理清洁产品，这些产品是没有添加任何化学防腐剂，比如，甲醇，苯酯酸醇类的产品。

About 100% yield of cyclohexanemethanol could be obtained in the presence of triethylamine if adding more catalyst and prolonging the reaction time.

在三乙胺存在下，增大催化剂用量并延长反应时间，苯甲醛可以100％的收率转化为环己基甲醇，没有出现任何副产物。

Objective: To establish the method of detecting methanol, benzene, toluene and xylene with gas-chromatography in the air of workplace.

目的：探讨一次采样气相色谱同时测定工作场所中甲醇、苯、甲苯和二甲苯的方法。

In this paper, the short-time photodissociation dynamics of benzanilide in methanol and acetonitrile solution has been studied by resonance Raman techniqueand quantum chemistry calculations.

采用共振拉曼光谱技术和量子化学计算研究了苯甲酰苯胺在甲醇和乙腈溶液中的短时光化学动力学行为。

In this thesis, investigations focused on heteropoly acids-catalyzed C-C and C-N bond formation reactions and the synthesis of xanthenediones and acridinediones under thermal conditions are described.1.12-Phosphotungstic acid has been used as an efficient,eco-friendly,and air- and moisture-stable catalyst to promote the direct dehydrative substitution of the hydroxy group of benzylic and allylic alcohols with variousβ-dicarbonyl compounds.

本篇论文主要描述了杂多酸催化下的C-C和C-N键的生成，以及无溶剂直接加热下合成十氢氧杂蒽二酮和9-芳基十氢吖啶二酮。主要内容如下：1。在磷钨酸催化下，1，3-二羰基化合物与醇能够顺利偶合，脱除一分子的水，生成烷基化的1，3-二羰基化合物。反应在甲苯中进行时，二芳基甲醇能与各类1，3-二羰基化合物反应，成率很高；但对于1-苯乙醇，只能得到很低的产率。

HZSM-5 has a higher catalytic desulphurization activity, and thiophene reacting with carbonium ion which produced by methanol and ethanol over HZSM-5 is converted into sulfide hydrogen and a few amount of alkylthiophene.

结果表明：HZSM-5对于脱除焦化苯中的噻吩具有较高的活性及活性稳定性，噻吩与甲醇、乙醇反应，绝大部分被分解生成硫化氢气体逸出，而极少生成重组分的烷基噻吩。
