摘要
A simple collisional three-component plasma model consisting of electrons, ions, and neutrals with arbitrary collision frequencies and dynamic time scales is considered. For the partially ionized plasma with a strong collisional coupling of neutrals with ions, magnetosonic and Alfv,n waves modified by neutrals are obtained. It is shown that the magnetic diffusivity appears for magnetosonic waves as a result of the ion transverse collision current connected with the field E (1aSyen) and for Alfv,n waves because both the ion transverse collision current and the electron longitudinal collision current are connected with E (1z) at the angular propagation of perturbations relative to the background magnetic field. <br xmlns:set="http://exslt.org/sets">The model can be applied to different parts of the solar atmosphere and prominences.
