... Nonlinear Ion Acoustic Waves in a Magnetic Plasma . ... These waves are described   by well known and sufficiently complicated nonlinear system of the three equations for the three desired function - the ions flow velocity, the electron (ion) density and the electrical field potential. ... As a result we find for all three desired functions quasi-monochromatic wave motions with a   general phase. In the frame of these motions explicit approximate formulae for all desired functions are constructed. ...
