Abstract
A problem of the crossover from percolation to diffusion transport is consi dered. A general scaling theory is proposed. It introduces phenomenological ly four critical exponents which are connected by two equations. One expone nt is completely new. It describes the increase of the diffusion below perc olation threshold. As an example, an exact solution of one-dimensional latt ice problem is given. In this case the new exponent q=2.
