本文分析了由非磁化麦克斯韦离子和磁化麦克斯韦电子组成的伏拉索夫等离子体中静电波的线性色散关系。电子经历E × B和E × B漂移，电子β很小。对于垂直方向的传播，最大增长率可以大大大于零磁场离子声不稳定性。对于从垂直线向外几度的传播，色散特性基本上是离子声不稳定性的那些。
This paper presents an analysis of the linear dispersion relation for electrostatic waves in a Vlasov plasma of unmagnetized, Maxwellian ions and magnetized, Maxwellian electrons. The electrons undergo E × B and ∇B drifts, and the electron β is small. For propagation in the perpendicular direction, maximum growth rates can be substantially larger than those of the zero magnetic field ion acoustic instability. For propagation outside a few degrees from the perpendicular the dispersion characteristics are essentially those of the ion acoustic instability.
