| 英文摘要 | Dispersive magnetohydrodynamic (MHD) waves with short-wavelength modification have an important role in transforming energy from waves into particles. In this paper, based on the two-fluid mode, a dispersion equation, including the short-wavelength effect, and its exact solution are presented. The outcome is responsible for the short-wavelength modification versions of the three ideal MHD modes (i.e. the fast, slow and Alfv,n). The results show that the fast and Alfv,n modes are modified considerably by the shortwavelength effect mainly in the quasi-parallel and quasi-perpendicular propagation directions, respectively, while the slow mode can be affected by the short-wavelength effect in all propagation directions. On the other hand, the dispersive modification occurs primarily in the finite-beta regime of 0:001 < beta < 1 for the fast mode and in the high-beta regime of 0:1 < beta < 10 for the slow mode. For the Alfv,n mode, the dispersive modification occurs from the low-beta regime of beta < 0:001 through the high-beta regime of beta > 1. |
