For the A_n B_m—A_n' C_m' system (valency of A ion is Z):f(r)=(Z~2nn')/(m(r_A+r_B))+(Z~2n'~2)/(m'(r_A+r_C))-(2Z~2nn')/(2r_A+r_B+r_C)(n'/nm'+1/m)n>n'. For A_nB_m—C_n'D_m' system (valency of C ion is Z'): f(r)=(n'Z'Z((n+nZ)/(n'Z')m'))/(m'(r_A+r_D))+nZZ'(m+nZ/Z')/(m(r_B+r_C))-(nZ~3(n+m))/(m(r_A+r_B))-(n'Z'Z(n'+m'))/(m'(r_C+r_D)). The "energetic parameter of solution" is an approximate function of electrostatic energy of mixing of molten salts. When f(r) is positive, the solution exhibits negative deviation; when f(r) is negative, the solution shows positive deviation. The function f(r) may be used as an approximate method to estimate the thermodynamic properties of molten salt solutions, as well as phase diagrams of binary salt systems. 收稿日期: 1964-02-18      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 陈念贻 张桂成 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1964/V7/I2/111 [1] Forland, T.: J.
