【Abstract】 Some explicit analytical solutions of nonlinear coupled scalar field equations are presented by means of direct method and hypothesis method. To the soliton solutions of the equations in some literatures, a more general form is given and the span of their parameters is extended. The results in this paper are the extension and improvement of the known results.更多还原
