The phase transition on the structure of spin net is considered. The Gaussian fluctuation of order parameters is used. The numerical calculation for 2– and 3–dimensional nets with different longitude of links for the Hamiltonian of an Ising model are given. It is demonstrated that such an approximation describes the temperature dependences of phase transition parameters rather well and the comparison with the mean field approximation is performed.
