还原剂

It introduces the production situation and problems which coke is partly replace d by semicoke coal as reductant in ferroalloy production.

介绍了铁合金生产以半焦煤代替部分冶金筛下焦炭作还原剂的生产情况和出现的问题。

Coke acts the three main functions which are reductant, thermite and stock column skeleton in blast furnace.

焦炭在高炉冶炼过程充当着还原剂、发热剂和料柱骨架的三大作用。

Which was same to the order of relative content of As-GSH in root of those three plants, indicating that GSH might act as the reductant in As to As transformation.

这与3种植物根部As-GSH的相对含量的顺序相同，表明GSH可能在还原过程中起还原剂的作用。

Wetter was found to be a key to coating preparation. It not only wetted and dispersed metal powder but also acted as reductor during the period of sintering.

得出润 湿剂是关键性的组份，在涂液配制和涂覆时润湿分散金属粉，而且在烧结过程中作为还原剂。

Compared with mixture of heavy oil and diesel oil, by using this new type reductant, it is possible to stop generation of black smoke in the reduction period of copper refining by reverberatory furnace, thus shortening reduction time and reducing operating cost.

与重柴油相比，使用煤基-α2β3γ3新型还原剂在铜反射炉精炼还原期间可杜绝黑烟的产生，还原时间缩短，生产成本降低。

Study on Improvement of Recovery of Gold and Silver from the Copper Dross Smelting in Reverberatory Furnace;2. After that, the copper in leach liquor can be extracted with the ternary extractant mainly containing P204, and the gold and silver in leach residue can be recovered by a process of cyanidation-replacement of Z.

为避免硫酸烧渣对环境的污染，以硫酸烧渣为原料，通过添加活性还原剂，用废硫酸直接还原浸出铁并制铁黄，而后用以P2 0 4为主体的三元萃取剂萃取回收浸液中的铜，用全泥氰化和锌粉置换工艺从浸渣中提取金银，较经济有效地回收利用了烧渣中的有价金属，铁、铜和金的回收率分别达到了 93。

It may participate in many biochemical reactions in the human body, can be partially oxidized deoxy-vitamin C, this process is reversible, so the oxidation of vitamin C is also a reducing agent.

它可参加人体内的很多生化反应，可部分氧化生成去氧维生素C，这一过程又是可逆性的，所以维生素C也是一种氧化还原剂。

Igneous electricity flue gas takes off saltpetre system whether achieve take off saltpetre rate and low ammonia gas high to escape rate, depend on greatly the flue gas is medium nitrogen oxide before entering saltpetre reactor and reducer ammonia gas blend even degree and flue gas speed to distributing.

梗概： 火电烟气脱硝系统能否达到高脱硝率和低氨气逃逸率，很大程度上取决于进入脱硝反应器之前烟气中的氮氧化物和还原剂氨气混合均匀程度和烟气速度分布。

It was also found that the activity of glycine decarboxylase increased with incre- ase in nitrate concentrations in the sandculture medium.

但他们认为在体内，这种还原剂可能全部用于过氧物酶体中经基丙酮酸到甘油酸的反应。

Base.H+］, whose stability is close to that of the product, may coexist with amine salt of hydrogen selenide［HSe-］.

Base.H+］的稳定性与产物接近，可以和HSe的铵盐共存，而且，按照理论计算的结果，这种物质可以作为还原剂。

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。
