摘要
利用x2=g(x)进行迭代,从而求出非线性方程f(x)=0的根x*,是继用x=g(x)的简单迭代法的延拓,讨论抛物线迭代法的具体方法和步骤,给出收敛性定理.
Using x^2 = g（x） to go for alternative, and to solving root x^＊ of nonlinear equation f（x） = 0 is a continuation of using x= g（x） briefness alternative manner. Talking over concrete method and steps of parabola alternative manner and give astringency theorem.
