In this program system, it contains the following 7 functions: (1) automatically balance the stoichiometric constants of all possible reactions, (2) carry out the Gibb,s free energy calculation of all possible reactions, (3) automatically cancel out the non-existence phase in the designated condition, (4) calculate out all of the locations of 3 phase intersections, 2phase cross lines, (5) find out the phase name, (6) find out the temperature profiles to be interested in, and (7) select the appropriate parameters. This program system has been used in the field of pyrometaUugy for explaining how to select the best operating condition. 收稿日期: 1984-02-18      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 王乐珊 许志宏 李大年 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1984/V20/I2/188 1 Linkson, P.
