系统地评估了铁氧化物还原动力学中氧化物型杂质或添加剂的影响，进行了必要的量化分析．其影响的特点与杂质含量，杂质存在形式和加入方法，样品的初始化学组成和物理性状，还原剂的种类，反应温度，还原分数等多种因素有关．
The effects of oxide-type impurities or additives in the iron oxide reduction kinetics were systematically evaluated and the necessary quantitative analysis was performed. The characteristics of its influence are related to the content of impurities, the existing forms and methods of adding impurities, the initial chemical composition and physical properties of the sample, the type of reducing agent, the reaction temperature and the reduction fraction.
