Abstract The equations of the central atoms (CA) model are simplified and derivatived in this paper. The new equations are similiar to the equations of ordinary thermodynamic models used usually, the static value difference between the i atomic state and is not need in proportion to, where i denoted there are i atoms B in the nearest neibouring shell of central atom or. The total of the probability of every atomic state, Pa equals to the reciprocal of activity coefficient of component a. The Ag-Cu diagram and its thermodynamic properties are calculated by this model, and the results coincide well with experimental values.
