摘　　要：基于辅助方程提出一种求解非线性演化方程的新方法,该方法简单易行且具有一定的普适性,根据不同的参数可给出各种形式的精确解,从而有助于探索非线性方程的新解及其性质。并以mKdV方程为例,得到了其多组精确解,包括Jacobi椭圆函数解及Weierstrass椭圆函数解等,除涵盖了以往结果,还给出一些新解。A new algebra method for constructing exact solutions of nonlinear evolution equations is proposed based on the auxiliary equation. The method is simple and universal. It can give various types of exact solutions according to different parameters, which are helpful to seek more new exact solutions and explore properties of nonlinear evolution equations. Many kinds of explicit solutions including Jacobi and Weierstrass elliptic function solutions are obtained, some of which are new
