Finally, it was applied to manganese oxide reduction reaction and obtained a third--order expression, which well conforms to the experimental data. The thermodynamics of irreversible process after considering the high--order term can be applied to slag—metal reacting systems far from equilibrium. Key words： thermodynamics of irreversible process    manganese oxide reduction    收稿日期: 2003-03-18      ZTFLH:  O642.1   服务 把本文推荐给朋友 加入引用管理器 E-mail Alert RSS 作者相关文章 翟玉春 王锦霞 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y2004/V40/I3/305 [1] Xu C D, Lin R.
