States of a one-dimensional electron flow

Resumo

The steady states of a 1D electron flow of electrons interacting with their self electric field are studied. A system of equations taking into account the hydrostatic pressure is reduced to a first-order nonlinear equation; partial solutions of this system are obtained. The possibility of exceeding of the ion sound velocity by ions is demonstrated. The behavior of a flow described by the adiabatic state equation is considered.
