摘要：
The asymptotic behavior of wave packets is investigated in an unstable plasma, described by the Vlasov equations with a beam. The instability is shown to be convective. The asymptotic growth rate of the wave packets in the limit t yields infinity is found along the rays x equals Ut. The boundaries of the region in which perturbations grow are found on the velocity axis. This region consists of three segments, which are related to unstable wave branches of the beam ions, the plasma ions, and the beam electrons.
