氧化还原

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。

The pigment of Berberis heteropoda Schrenk is a type of anchocyanin and it is strong in resistance against light and to some extent, good in enduring heat and low consistence oxide. But it is poor in resistance against reductant and preservative. It can be applied to the condition of PH. It is also found that sucrose and most of metal ions do not exert negative effects on the stability of the pigment, except Fe3+, Fe2+and low consistence Pb2+, which have some extent effects. Adding stability matter can improve its stability. The harm trace elements contains are within requirement of the National Standard on food safety, As the lexicological study indicates that the pigment does not have any toxicity and mutagenesis, it can be used as edible pigment.

结果表明：大孔树脂吸附-解吸附法纯化黑果小檗色素实验室工艺简单易行，色素回收率高；黑果小檗色素属于花色苷类色素；耐光性好；对热有一定耐受性；对低浓度氧化剂有一定耐受性；耐还原性差；对防腐剂耐性差；适用PH＜6条件下使用；蔗糖和大多数金属离子对色素无不良影响，但Fe~(3+)、Fe~(2+)、Sn~(2+)和低浓度pb~(2+)对色素有影响，加入稳定剂后，可提高色素的耐热性、耐氧化性、耐防腐剂能力；经对有害微量元素进行检测和毒理试验表明，该色素安全无毒，可以作为天然食用色素使用。

The results showed that for carbon steel exposed to sea water for 1~120 month, there were large quantities of SRB congregating in the internal rust layer, arid synchronously there were different numbers of heterotropic bacteria, iron bacteria and sulfide-oxidizing bacteria.

通过在海水中现场挂样，检测了碳钢内锈层中的硫酸盐还原菌、异养菌、铁细菌和硫氧化菌的数量，用SEM观察了内锈层中腐蚀性细菌的形态和分布，并测定了内锈层中的FeS含量，研究了内锈层中微生物对碳钢海水腐蚀的影响及碳钢内锈层中的微生物及其腐蚀与大型生物、锈层、温度等的关系。

For anti-oxidation properties, methanolic extracts from fruit bodies and mycelia showed excellent scavenging ability toward DPPH (1,1-diphenyl-2-picryl hydrazyl)(96% at 15mg/mL) and good potential in reducing ability at the concentration of 2.5 mg/mL and chelating effect on ferrous ion (about 82% and 77% for extracts from mycelia and fruit bodies, respectively) at the concentraction of 2.5 mg/mL.

在抗氧化性质方面，结果显示子实体和菌丝体的甲醇萃取物在浓度为15mg/mL时，对DPPH（1，1-diphenyl-2-picryl hydrazyl）自由基清除率高达96﹪和89%，在浓度为2.5mg/mL时就具有好的还原能力，菌丝体和子实体甲醇萃取物在浓度於2.5 mg/mL时，对铁离子螯合能力分别达82﹪和77﹪。

First, 5-nitro-1 and 4-naphthoquinone are prepared through nitration and oxidization of naphthalene, and then through reduction of nitro into amide, diazotisation of the amide and hydro-lytic action of diazo salt, the juglone is made.

萘经过硝化、氧化生成5-硝基-1，4萘醌，然后硝基还原成氨基、氨基重氮化、重氮盐再水解，最终用新方法制得胡桃醌。

Chinensis and Kuruma prawn M. japonicus increased at 12 and 48 hours post-inoculum, but decreased sharply after 36 and 72 hours post-inoculum respectively. LPS inducible NOS activity also decreased significantly with the time elapsed in WSSV infected shrimps. Results of WSSV detection with the Dig-DNA Probe dot blot hybridization test showed that WSSV of the two penaeid species couldn't be detected until iNOS started decreasing.

在此基础上，我们建立了对虾血细胞中诱导型一氧化氮合成酶的鉴定方法—硝基四氮唑蓝还原法和血细胞形态法以及酶活力的测定方法—L-瓜氨酸分析法和亚硝酸盐分析法并优化了鉴定和测量条件，结果显示：对虾血细胞在4℃下与L-精氨酸和LPS孵育8h以及当L-精氨酸浓度为2.5mmol l〓LPS浓度为100μg ml〓，Ca〓浓度为2.5mmol l〓时，iNOS活力的测定结果最佳。

"Synthetic indigo has replaced the natural dye; it is reduced chemically to the soluble yellow compound leucoindigo, in which form it is applied to textile fibres and reoxidized to indigo (see oxidation-reduction)."

天然靛蓝逐渐为合成靛蓝所取代；经化学反应可把它还原成可溶靛白，后者施于纺织品上，然后再氧化成靛蓝。

Catalysts used for abating the pollution of automobile exhaust emissions were prepared by nonprecious metal oxides, such as the oxides of Ⅰ B,Ⅴ B,Ⅵ B,Ⅶ B,Ⅷ B group, alkaline earth group and rare earth elements.

在实验室用模拟汽车排气，评价催化剂的氧化、还原效率，获得了具有较低起燃温度的催化剂(对于CO低于150℃HC为200℃)，机械强度良好，而且可承受高温冲击(耐温可达900～1000℃)。

It is working great with respect to water-proofing, scratch-proofing, color-retaining, high transparency, low oxidability, corrosion resistance and so on.

在防水抗划、色牢度、透明度、氧化度、粘合度、色彩还原度和耐磨力等方面均表现出色，使每一幅经制作后的画面古朴而典雅、妍丽而不张扬，与黄金的相融又熠熠生辉，具有很高的观赏和收藏价值。
