Some new exact Jacobian elliptic function solutions of three kinds of nonlinear evolution equations
三类非线性演化方程新的Jacobi椭圆函数精确解

By using the modified mapping method, we find some new exact solutions of the nonlinear Klein-Gordon equation, mKdV equation and the generalized Boussinesq equation. The solutions obtained in this paper include Jacobian elliptic function solutions, combined Jacobian elliptic function solutions, soliton-like solutions and triangular function solutions.
