【Abstract】 By introducing a transformation and selecting the appropriate trial functions,a concise method ispresented to construct the sech2-type solitary wave solutions of nonlinear wave equations.The effectiveness of thismethod by applications to three equations with physical interest as particular examples was got.The technique usedherein can also be applied to seek the sech2-type solitary wave solutions to other nonlinear wave equations.更多还原
