Abstract: With the classical Nucleation theory and the combination of Monte Carlo method, the two dimensional model of liquid phases separation for binary system is present. It consists of three parts of nucleation, diffusion and growth The some methods dealing with problem of surface energy in the growth of new phase are raised. The principal procedure is shown for the simulation of phases separation with computer.

Key words: nucleation decomposition, phases separation, two dimesional model, computer simulation
