The S entering into pellet with concentrate is pyrite, with coal powder are iron sulfide, sulphate and organic sulphur, when reducing, S existing in pyrite, iron sulfide and organic sulfur come into gas phase, then been absorbed by fresh Fe and liberate out of pellet, combined with CaO existing in outside of the pellet to form CaS finally, sulphate will remain in DRI.

当还原温度高于在铁碳相图中的最低液相线温度1147~1153℃时，渗碳作用导致DRI外壳熔化，这层致密的熔融外壳起到热态直接还原铁的防氧化作用。低于这个温度将有助于还原和脱硫。

Having reviewed a large number of relevant literature in detail, combined with some research achievements at sandstone type uranium deposits in China and abroad, The authors try to make an overview of the role of sulphides, particularly the pyrite, in the reduction, precipitation and concentration of uranium at the redox front of sandstone type uranium deposits.

作者通过大量的相关文献的调研，结合国内外在砂岩型铀矿研究方面取得的成果，对硫化物，特别是黄铁矿在砂岩型铀矿氧化－还原前锋线附近铀还原、沉淀和富集过程中所起的作用提出了自己的认识。

At the same time, the conversion efficiency of NO〓to N〓 was improved by plasma and the selectivity to N〓 formation was enhanced from 1.1% to 1.53%. 4. TPR experiment of simultaneous removal of PM and NO〓 were carried out by plasma/catalysis techniques. The PM was obtained by putting the γ-Al〓O〓 spherules in the diesel exhausts.

选用75％负荷工况挂烟得到的PM的程序升温反应试验结果显示，CO〓和N〓产生在相同的温度范围，表明PM的氧化和NO〓还原同时发生，而且是NO〓和PM的相互作用的结果，并且，PM燃烧得到的程序升温反应曲线是双峰曲线，NO〓在低温段和高温段分别被可溶性有机物SOF和干碳烟DS还原。

The further results show that electronic products can be sintered not only under low concentration reducing atmosphere, but also by rasing sintering temperature under oxidating atmosphere.

不同还原气氛浓度下烧成实验结果表明：电瓷制品不仅可以在较低还原气氛浓度下烧成，而且也可以在提高氧化气氛烧成温度条件下烧成。

The results also prove that products should be oxidated first in order for reducing start temperature to low in course of reducing atmosphere sintering.

Dehydroascorbate reductase catalyzes the re-reduction of DHA to ascorbate by glutathione. Thus, dehydroascorbate reductase is critical for protection of cellular components against oxidative injury.

脱氢抗坏血酸还原酶以谷胱甘肽为底物，催化脱氢抗坏血酸还原为抗坏血酸，在循环利用抗坏血酸、保护细胞组分抵御氧化损伤中发挥重要的作用。

REE geochemical characteristics and their systematic changes in the sedimentary section suggest that there existed a process of ingression-regression in this area in the early Cambrian period. The black shale series resulted from the mixing between normal seawater sediments and hot seawater sediments and were deposited under the transitional condition from reduction to semi-reduction and weak oxidation in a shallow-sea clinoform zone of a relatively deep sea environment with dry climate.
