Query: Behaviour of plasma with arbitrary degree of degeneration of electronic
  gas in a slab of conducting medium   The analytical solution of the boundary problem on behaviour (oscillations)
of the electronic plasmas with arbitrary degree of degeneration of electronic
gas in a slab of the conducting medium is received. The kinetic
Vlasov---Boltzmann equation with integral of collisions type BGK (Bhatnagar,
Gross and Krook) and Maxwell equation for electric field are applied. Mirror
(reflections) boundary conditions are used.
