The results obtained can be expressed as follows: R_(Al)=-2.91(%Ca)~2+3.51(%Ca)+3.05 and the interaction coefficient can be evaluated as lgf_(Al)~(Ca)=-0.441(%Ca)~2+0.476(%Ca) with Ca content within the range of 0 to 0.54%. The interaction parameters e_(Al)~(Ca) and e_(Ca)~(Al) are evaluated as 0.476 and 0.705 respectively. Preliminary results obtained on the distribution of Ce between Ag and Fe show that R_(Ce)(=[%Ce]_(Fe)/[%Ce]_(Ag)) is as low as 3.70×10~(-3). Besides, some thermodynamic functions are also deduced from the experimental results mentioned above. 收稿日期: 1986-05-18      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 周继程 田彦文 马永慧 朱立民 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1986/V22/I5/78 1 Chipman, J., Trans.
