The average electron thermal energies in the emission flux from the electrode into the plasma, Ä–, and from the plasma toward the electrode, Ä–, are determined for the cases of large and small values of the coefficient of kinetic reflection. It is shown that these energies vary within the ranges 0.5 k T < Ä– < 2 k T and 0.5 k T < Ä– < 2 k T, where T and T are the temperatures of the cathode and plasma electrons, respectively. The obtained values can be used to formulate the boundary conditions for the hydrodynamic equations at the electrode or a dielectric wall.
