The Peculiarities of Nonstationary Formation of Inhomogeneous Structures   of Charged Particles in the Electrodiffusion Processes
  In this paper the distribution of charged particles is constructed under the approximation of ambipolar diffusion. The results of mathematical modelling in two-dimensional case taking into account the velocities of the system are presented.
