The investigation also showed that, the antioxidants with same action mechanism, for example, as both radical scavengers, phenol and amine antioxidants are synergistic; but the synergistic effects between two antioxidants with different action mechanism, such as radical scavenging phenol and amine antioxidants, and hydroperoxide decomposing ashless dithiocarbamate, are much stronger, and the heterosynergism between dithiocarbamate and alkylated diphenylamine is outstanding, which can serve as high temperature ashless high performance antioxidant combination; the heterosynergism among three antioxidants with three different action mechanisms, for example, the tri-component combination of alkylated diphenylamine, zinc dithiocarbamate and organic molybdate ester, can achieve excellent antioxidation performance.

研究还表明，具有相同抗氧机理的不同抗氧剂，如酚类和胺类抗氧剂，具有协同作用；不同作用机理的两抗氧剂之间，如自由基清除剂和氢过氧化物分解剂，具有更好的抗氧化协同效果，其中，无灰氨基甲酸酯与烷基化二苯胺抗氧剂具有最佳的抗氧协同效能，可成为高温无灰抗氧剂应用的一个很好选择；不同抗氧机理的三种抗氧剂复合，如烷基化二苯胺，氨基甲酸锌和有机钼酸酯组成的三元复合抗氧剂，具有更为优秀的抗氧化性能。

The oxidation of methyl linoleate was inhibited by β-carotene, lutein and bixin in a dose-dependent manner. Lutein and zeaxanthin suppressed the hydroperoxide formation more efficiently than β-carotene and bixin at 41.7×10-6mol/L. Lutein inhibited the oxidation of methyl linoleate as efficiently as zeaxanthin.

表明β-胡萝卜素，叶黄素及胭脂树橙都按依赖于剂量的方式抑制亚油酸甲酯氢过氧化物的形成。41.7×10 -6mol/L的叶黄素及玉米黄质的抑制活性相近，高于β-胡萝卜素与胭脂树橙的活性，后两者活性近似。

Second, investigations were made in the effects of polymerization of HRP on its catalytic activity in the excess of H〓O〓 by the use of fluorogenic hydrogen donors of HRP. The results showed that some HD, e. g. homovanillic acid could indicate the activity differences between HRP and polymerized HRP.

其次，为建立辣根过氧化物酶标记的调制型荧光免疫分析研究了用荧光供氢体代替显色供氢体指示聚合前后辣根过氧化物酶在高浓度H〓O〓中活性的差异。

Aging mechanism of wood-plastic composite was: light and heat break down the long molecular chains of wood flour and plastic; the free radicals reacted with the oxygen, which generated carbonyl groups, hydroperoxides and so on; the free radicals also had cross linking reaction, which generated alkoxy; Water destroyed the interface of wood flour and plastic, hydrolyzed ester additives, extracted the small molecule additives and degradation products; Microorganism degraded cellulose, semicellulose, lignin and ester additives; degradation product from different component accelerated the aging, which could be exampled by the fact that HCl from degradation of PVC accelerated the hydrolyzation of cellulose and semicellulose.

木塑复合材料的老化机理为：光和热引发木塑复合材料中木质组分和塑料组分大分子链断裂，产生的自由基与氧气作用，发生链支化反应生成羰基、氢过氧化物等，发生交联反应生成烷氧基等；水分破坏木-塑界面、水解酯类添加剂、抽提小分子添加剂和降解产物；微生物分解纤维素、半纤维素、木素和酯类添加剂；木塑复合材料中各组分的降解产物相互促进老化，PVC降解产生的HCl溶于水，促进了纤维素和半纤维素的水解。

However, under the experimental conditions used for these tests, carbonyl compounds may be generated by decomposition of unstable intermediates, such as hydroperoxides, thus detracting from accuracy of the results.

然而在这些试验的试验条件下，羰基化合物会由于不稳定中间体的分解产生，如氢过氧化物，因此结果会偏离准确值。

MethodsErgosterol was separated from Bulgaria inquinants and oxygenized ;its analogue 7-dehydrodesmosterol was also oxygenized. The antituberculous activity of oxygenized products were detected using MTT method.

方法从胶陀螺中分离得到麦角甾醇，对其氧化得到麦角甾醇过氧化物；并对麦角甾醇类似物7-脱氢胆甾醇进行氧化得7-脱氢胆甾醇过氧化物；用MTT法检测其氧化产物的抗结核活性。

He said older cleansers such as soap and hot water, alcohol, chlorine bleach and hydrogen peroxide are sufficient for most purposes.

他说：沿用至今的清洁剂，诸如肥皂，热水，酒精，氯漂白剂和氢过氧化物，足以作多种用途。

Dispose of all items used for the biocide properly Hydrogen Peroxide · 30% H2O2 is concentrated, however, no dilution is required.

在biocide适当被使用了的所有的条款的处理氢过氧化物· 30% H2O2是专注，然而，没有稀释被要求。

A visual-spectrophotometry method for peroxide value of oil-in-water emulsions was studied in this paper.

本实验采用分光光度法对国内现有的乳状液中氢过氧化物含量的测定方法进行改进。

As far as oxidation is was concerned, the major concern lied with the fatty acids in the system. The oxidation of most of the fatty acids was attributed to the activity of lipoxygenase in barley and malt although other oxidations also exist such as auto oxidation (non-enzymatic), hydroperoxide decomposition and so on. This enzyme is was partly responsible for the development of the 'stale','cardboardy' flavour in beer during storage, and has been a great concern for brewers and the brewing industry.

在制麦和糖化过程中，尽管存在酶的自氧化和氢过氧化物的降解等，但绝大部分脂肪酸的氧化则是由大麦和麦芽中的脂肪酸氧化酶引起的，该酶对于在啤酒存储过程中纸板味的出现起了部分作用，因此引起了酿造者和啤酒企业的极大重视。

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。
