Bipolar problem of space-charge in dielectric : I. System without trapping.

A model of a dielectric with bipolar injection of charge in the form of a plane parallel capacitor is presented. Space and time distributions of charge and induction as well as time courses of the resorption current were determined. The resorption state is described by partial differential equations. Initial conditions were determined on the basis of the stationary state of absorption. The theory of partial quasi - linear differential equations was used in the analytical and numerical considerations
