研究了电子平行于磁场流动的有限β非均匀等离子体中低杂波的线性和拟线性理论。这些波在极低β时是不稳定的，在有限β等离子体中是稳定的。不稳定波的准线性反馈导致垂直于平衡磁场的离子加热。因此，不稳定的低杂波可能在极光区产生离子锥和加热太阳等离子体中的离子方面发挥作用。
The linear and quasilinear theories of lower hybrid waves in a finite-β inhomogeneous plasma with electrons streaming parallel to the magnetic field are examined. These waves are found to be unstable for very low-β and to be stabilized in finite-β plasmas. The quasilinear feedback of unstable waves is shown to result in heating of ions perpendicular to the equilibrium magnetic field. Thus, unstable lower hybrid waves may play a role in producing ion conies in the auroral zone, and in heating ions in the solar plasma.
