Abstract Three kinds of partial simple solutions——partial ideal solution,partial regu- lar solution and partial dilute solution——were defined.Treating the iso-μ_A or iso-_A molecules A in the A_pB-A_qC pseudobinary system as medium and using the quasi-lattice model,the theory of partial simple solutions is presented to ex- plain the simple behaviour of ternary systems which was discussed by macroscopic thermodynamic method in the author's previous papers.Combining the above treat- ment with the Temkin's assumption,this theory may also be applied to the molten salt mixtures.The behaviour of the pseudobinary systems of type A_pB- A_qC may be: ΔS~(PE)=0,ΔG~(PE)=ΔH=0 for the ternary partial ideal solution;or ΔS~(PE)=0,ΔG~(PE)=ΔH=Lw_(BC)x_Bx_C for the ternary partial regular solution;or,over y<0.01 roughly speaking, ΔG~(PE)=K_(C(G))x_C (K_(C(G))=Lw_(BC)x_(B(A))≠0) for the ternary partial dilute solution;in which y=x_C/x_(C(A)), and ΔG~(PE)=-TΔS~(PE)=ΔG-RT{x_Bln[x_B/(x_B+x_C)]+x_Cln[x_C/(x_B+x_C)]},x is the mole fraction and L is Avogadro's number.The thermodynamic properties thus calculated are in agreement with the published experimental data for the systems AgCl-NaCl-RbCl,Na-Pb-Tl,Cd-Bi-Sn,Cd-Pb-Sn,Cd-Pb-Bi and C_(sat).-Fe-Ni respec- tively.This theory was extended to the systems of more than three components,
