Calculation of percolation conductivity in 3D

The authors calculate the critical exponent of percolation conductivity for 35*35*35 three-dimensional network by using Monte Carlo simulations. They obtain the critical exponent t to be equal to 1.90+or-0.10 and discuss the values of t in terms of present models of backbone of infinite cluster. They also obtain the critical exponents beta =0.38+or-0.02 and beta '=0.93+or-0.03.
