Critical and non-critical exponents of percolation theory of electric conductivity

In this paper the results of investigation of percolative model for metal electroconductive properties evolution are presented. This evolution is the result of crystal lattice destroying. Method of calculation for resistance of this lattice is constructed. Authors presents the results of computer experiments which gives dependence of conductivity from procent of destroyed bonds in lattice. Three regimes corresponding to three sections of dependence diagram are distinguished. For each section the conductive exponents are calculated. Modification of standart relaxing method used for solving of Dirichle problem is suggested.
