| 摘 要： | 本文通过引入动力系统，将改进的Euler方法应用于非线性方程求根问题，给出非线性方程求根的预估-再校正迭代格式，证明了该格式至少二阶收敛并可以调节参数达到超收敛。最后给出数值实验，数值结果验证了算法的有效性。

| Abstract: | By Introducing the dynamic system,Improving Euler Methods are used to solve the roots of nonlinear equation, We deduce the Predict-Recorrect for solving roots of nonlinear equations to prove the quadratic convergence under weak conditions.In the end,we give the numerical experiments,and the numerical results imply the efficiency of the Predict -Recorrect Iterative methods. |
