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.
