The ersults indicate that the formation of water soluble products were not simply due to the glucosidic bonds hydrolysis.It may be due to the breakage of the glucose residue cycle.The breakage of glucose residue cycle may produce reduce ends and result in unstablization of glucosidic bonds, leading to glucosidic bonds hydrolysis and release of water soluble produdts.

说明CDH作用于底物后生成的水溶性产物不是因为简单的糖苷键水解造成的，而可能是由于糖环的氧化断裂导致还原端的生成，并最终使得糖苷键不稳定而水解，释放出水溶性产物。

It was found that photochemical deposition of Hg occurred at the layer of TiO2 covering the surface of titanium electrode under UV irradiation, the adsorption of sulfadiazine on the photochemically deposited Hg was stronger than that on the electrochemically deposited Hg, and a method for the determination of sulfadiazine was proposed by the adsorptive stripping voltammetry based on photo-chemical deposition of Hg on Ti electrode.

经GC-MS分析发现该两细菌对-柠檬烯有显著的生物催化转化作用，能对底物进行不同程度的氧化、还原、水解、酯化、开环等反应，并产生丰富的系列结构不同的其它萜类化合物：包括单萜、倍半萜、二萜、以及三萜等。

Therefore, we characterized the Cyt c P71H/M80V variant protein electrochemically and spectroscopically. All the experimental results showed that the introduced histidine at position 71 did not act as a functional distal-histidine, but most likely coordinated to the heme iron, maybe due to the flexibility of theΩloop segment (resides 70-84) of Cyt c protein.

于是我们对P71H／M80V蛋白性质进行了一系列的研究，结果表明可能是由于Cyt c中Ωloop D肽段(residues 70-84)具有很强的柔韧性，使得His71并没有象HRP中的distal histidine一样起到酸碱催化功能，而是与heme发生了配位作用，无论是在氧化态还是还原态都成了heme的第六轴向配体。

In this research, large volume stainless pots, high－quality pottery pots and enamel pots, instead of traditional small volume pottery pots, were used in storing several kinds of fresh liquor like "Shuanggou Liquor" etc.and the analysis of stored liquor by gas chromatography and atomic absorption spectrum indicated that the application of large volume stainless containers, instead of the traditional pottery pots, could not only advance liquor aging , produce flavour and remove precipitate, develop soft liquor style, stabilize and improve liquor quality,harmonize the balance of components , decrease liquor loss and liquor storage space,but also promote oxidation , reduction, esterification and molecular hydrogen bond association in the process of liquor storage.

对&双沟酒&等各香型酒，利用大容器的不锈钢罐、优质陶缸和搪瓷罐代替传统小容积陶坛或陶缸贮存新酒作了试验研究。采用气相色谱和原子吸收光谱对贮酒分析，得出采用不锈钢等大容器代替传统小陶罐贮存酒，不但可使酒在贮存过程中进行氧化、还原、酯化和分子氢键缔合作用，促进酒体老熟去杂增香，使酒体柔和老熟、成分平衡协调，稳定和提高酒质；而且还可以降低酒的损耗和减少贮酒库占地面积。孙悟

The mechanisms,characteristics and influencing factors of the sulfate reducing bacteria and the iron oxidizing bacteria are discribed in detail.
