摘要：
The universal expression of effective conductivity of weak non-linear media with the arbitrary current-voltage relation has been obtained near the percolation threshold. For the case of strong nonlinearity j similar to E-gamma, the critical behaviour of the effective conductivity calculated at the finite relation of conductivity, the violation of the conductivity scaling is observed.
