Abstract:

A class of the nonlinear disturbed Schrdinger coupled system was studied. With the help of  the functional mapping method and the technique to relate the exact and approximate solutions, the corresponding typical coupled system was considered. With the aid of  the variational iteration theory and approximate method, the shock wave asymptotic solutions of the disturbed Schrdinger coupled system were found. Unceasingly differential and integral operations of this approximate solution can  obtain approximations of dependent physical quantities.

Key words: Schrdinger system, solitary wave, asymptotic solution
