[en] As a demonstration of the connection between plasma fluid and kinetic behaviour, the general solution is outlined for electron oscillations, covering the entire range of khsub(D) where k is the wave number and hsub(D) the Debye distance. Charge separation produces an electric field which limits the electron excursions, thus acting as a 'fluid binding force'. In the limit khsub(D) >> 1 this force becomes weak and the electron gas exhibits a free-streaming behaviour which cannot be treated in terms of conventional normal mode analysis and macroscopic fluid equations. Thus, the moment equations become irrelevant in this case because they do not represent a solution of the Vlasov equation. Free streaming results in phase-mixing which has a strong non-resonent kinetic effect on the macroscopic features of plasma disturbance. If instead khsub(D) << 1, the same binding force becomes strong and makes the electrons behave largely as a macroscopic fluid. In this special case not only the macroscopic fluid-like features of the electron gas are recovered, such as the thermal pressure gradient effects of Tonks-Langmiur and Vlasov, but also those of Landau damping. The latter damping differs from that by phase-mixing due to free-streaming, in the sense that it is resonant and becomes related to the electric field. Thus, Landau damping comes out as a 'subsidiary' kinetic effect in an electron gas which largely behaves as a macroscopic fluid. (author)
