The general problems introduced into the modelling of ESR chemical reac tions by virtue of the various reactions stoichiomctries are discussed. In particular it is described the difficulties in using simplified reaction schemes such as the Mn/FeO/Fe/MnO exchange as the basis for modelling systems in which as many as eight separate reactions may require simultaneous equilibrium solutions. Based upon the penetration and film theories, a scheme of describing such systems is developed. The new model, theoretically, may be applied to any ESR system, i. e. to the ESR process of any steels and alloys, and the changes in composition of both metal and slag phases may be more precisely predicted. The theoretical model has been solved. The parameters for the model are discussed and determined. 收稿日期: 1984-05-18      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 魏季和 A.Mitchell 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1984/V20/I5/387 1 Hawkins, R.
