The results show that the perfect strength can be obtained under oxygen partial pressure about 20% O2, overhigh or low oxygen partial pressure is unfavorable for recrystallization of Fe2O3, which causes a decrease of pellet strength. The original hematite will be transformed into magnetite on reduction firstly when carbon-burdened hematite pellet is roasted in oxidizing atmosphere, and then the magnetite will be oxidized to secondary hematite, which is more active than original hematite, therefore, the induration strength of pellet is able to be enhanced.

研究结果表明：内配碳赤铁矿氧化球团在接近空气配比(氧含量约20%，体积分数)的氧化性气氛中焙烧强度最大，氧含量过高或过低都会影响Fe2O3的再结晶，使球团强度降低；在氧化性气氛中焙烧含碳赤铁矿球团时，原生赤铁矿先还原为磁铁矿，磁铁矿再氧化成活性较高的次生赤铁矿，提高了赤铁矿焙烧固结性能和球团强度。

Using the basic principle of the color fading of Mn(Na2HP2O7)3, due to oxidizing by oxidizable organic matter at concentrated H2SO4 the effects of different concentrations of organic carbon compounds, colorimetric conditions (temperature, color developing time and colorimetric wave length) and some intervening ions on the colorimetric determination of dissolved organic carbon were systematically studied.

利用紫红色络合物Mn(Na2HP2O7)3在浓H2SO4存在时可氧化有机质使络合物颜色变浅的基本原理，系统研究了不同种类、不同浓度的有机碳化合物、比色测定的条件(温度、显色时间和比色波长)与一些干扰离子对水溶性有机碳比色测定的影响。

Nitrite oxidoreductase was responsible for the nitrification of nitrite-oxidizing bacteria, which was coded by norB gene and others.

硝化菌主要由两大生理群组成：氧化氨氮为亚硝酸盐氮的是亚硝酸菌；氧化亚硝酸盐氮为硝酸盐氮的是硝酸菌，硝酸菌中负责硝化作用的酶是亚硝酸氧化还原酶，这个酶由norB等基因编码，因而对这个酶和基因的研究将有助于氮污染的控制和防治。

Nitrite oxidoreductase is the key enzyme responsible for the oxidation of NO2- to NO3- in nitrite-oxidizing bacteria.

亚硝酸盐氧化还原酶(nitrite oxidoreductase， NXR)是硝化细菌将亚硝酸盐氧化为硝酸盐的关键酶，广泛存在于亚硝酸盐氧化菌中。

The heart of the system is a special catalytic converter downstream of the oxidizing catalyst and the particulate filter.

该系统的核心是一个特殊的催化转化器催化剂的氧化和下游的微粒过滤器。

However, it is hard to prepare high valent Mn complexes with ligand with only neutral chelating nitrogen atom of two dpa arms in 〓. In order to get a Mn dimmer complex with high oxidation states of manganese to increase the possibility of storing more oxidizing equivalents necessary to oxidize water evolving oxygen, some N atoms are replaced by anionic phenolate groups.

本文以高价金属的稳定、氧化还原性能的改善、各金属离子之间联系的增强等作为主要研究内容，来改进以往模型中金属价态较低，氧化还原电位高，不利于形成氧化活性中间体；多核配合物的研究较少，且各金属活性中心相互协同作用弱等问题。
