英文摘要A Sagdeev equation is provided for the solitary kinetic Alfven waves (SKAWs) in a low-beta (m(e)/m(i)<>alpha > 1), three-component (electrons, protons, and heavy ions) plasma. Then we get the numerical solution of the equation. It is found that the density humps of SKAWs can exist in the sub-Alfvenic region. The heavy ion density amplitude and the width of the SKAWs rise with the increase in the initial density of heavy ions n(b0) in such bi-ion plasmas. The perturbed electromagnetic fields E-z, E-x, and B-y are also studied further to discuss the effects of heavy ions on them. Also, numerical outcomes have been offered for cases with several different parameters to illustrate these results. (C) 2005 American Institute of Physics.
