【Abstract】 By using the extended F-expansion method recently proposed,a number of periodic wave solutions to the nonlinear equation with variable are obtained,which are expressed by Jacobi elliptic functions.When the module approaches 1 or 0,the hyperbolic function solution(including the solitary wave solutions) and triangle function solutions are obtained.更多还原
