摘要
By introducing a transformation containing two unknown functions and selecting appropriate trial functions, we develop a simple and unified approach to construct the bell-type solitary wave solutions of nonlinear evolution equations (NEEs). We demonstrate the effectiveness of our approach by applications to some physically significant equations as particular examples. The procedure used herein can also be applied to seek the bell-type solitary wave solutions of other NEEs.
