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。

After As in WO3 is dissolved with NaOH solution, WO3 is coordinated by citric acid. In HCl medium, As is reduced to lwo valency As by KI and then low valency Asis reduced to gas AsH3 by SnO2 and metal Zn. After that, DDTC-Ag solution is applled as absorbent for colorimetric determinhtion.

用氢氧化钠溶液溶出三氧化钨中的砷之后以柠檬酸配位三氧化钨，在盐酸介质中用碘化钾将砷还原成低价砷，再用二氯化锡和金属锌将低价砷还原成砷化氢气体，以DDTC-Ag溶液吸收进行比色测定。

Results show that the adoption of stainless steel anode wrapped with anion membrane improves the bath stability and avoids the oxidation of manganous ions.

结果表明：采用不锈钢阳极和阴离子膜可提高镀液稳定性，防止二价锰被氧化，加入氢氧化钡可消除因补充锌锰离子而积累的硫酸根离子。

The substrates such as galvanized iron,aluminum and some alloys are prone to oxidi-ze and from a compact film of oxidization due to strong activity of metal.The conv-entional putties dont harden completely on the surface of substrates resulting in poor adhesion.

锌、铝等板材及某些合金因金属活动性强，表面易被氧化形成致密的氧化膜，对普通原子灰有效强的阻聚作用，所以普通原子灰在其表面固化不完全，没有附着力。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
