For the dyn.mics.of three-dimen.0}on.l electron.pos.tron.ion.plas.as. a fluid quan.um hydrodyn.mic model is.propos.d by con.0}derin.

The application.of the reductive perturbation.techn.que produces.a wave evolution.equation.repres.n.ed by a damped Korteweg–de Vries.equation. This.equation. however, is.in.0}fficien. for des.ribin. waves.in.our s.s.em at very low dis.ers.on.coefficien.s.
