The corresponding solution for a class of disturbed KdV equation is considered using the analytic method. From the generalized variational iteration theory, the problem of solving soliton for the corresponding equation translates into the problem of variational iteration. And then the approximate solution of the soliton for the equation is obtained. 相似文献

A Variational Iteration Solving Method for a Class of Generalized Boussinesq Equations 总被引:2,自引:0,他引:2 下载免费PDF全文
We study a generalized nonlinear Boussinesq equation by introducing a proper functional and constructing the variational iteration sequence with suitable initial approximation. The approximate solution is obtained for the solitary wave of the Boussinesq equation with the variational iteration method. 相似文献

Variational iteration method for solving perturbed mechanism of western boundary undercurrents in the Pacific 总被引:9,自引:0,他引:9 下载免费PDF全文
A class of perturbed mechanisms for the western boundary
undercurrents in the Pacific is considered. The model of generalized
governing equations is studied. Employing the method of variational
iteration, an approximate solution of corresponding model is
obtained. It is proved from the results that the solution for the
variational iteration method can be used for analysing operation of
the perturbed mechanism of western boundary undercurrents in the
Pacific. 相似文献
