Abstract
The influence of fluctuations in the number of Fermi particles on the charge state of fine-dispersed metallic grains in an insulating matrix is investigated. It is suggested that the system of grains does not form a tunnel medium and that charge transfer between metallic elements of the composite occurs due to thermal excitations of electrons over barriers. As follows from a calculation of the grand partition function, the average charge of the ith grain is a nonlinear function of the potential V i of the conductor.
