摘      要：The character of variations of the local electric resistance and magnetic susceptibility of film polymer composites with graded anisotropic structures on the basis of polyvinyl alcohol, graphite and nickel nano-powders have been studied. Graded anisotropic structures are formed after orientation （stretching） in spatial conditions of thin polymer composites. Structure anisotropy leads to anisotropy both electrical conductivity and magnetic properties of these films. It is established that the changes of these parameters essentially depend on both initial shape of the films and on direction of their orientation. So, after orientation of the rectangle films parallel to it any side forms the film, electrical resistance of which in parallel and rectangle directions to orientation axis changes by Gauss low. The composites containing the magnetic particles after orientation are characterized with analogical regularity （extreme dependence of the magnetic susceptibility on the coordinates of the film along and perpendicular to stretching directions）. Gradient distribution of the local resistances and magnetic susceptibilities in the stretched films along and rectangle to stretching direction is due to gradient of local deformations in the same directions. In electronics these films can be useful for preparing of muitifunctional printed circuits of new generation.
