| 摘 要： | 采用二分法预报、改进的Aitken迭代校正的方法，构造了一种非线性方程求根的一种新算法。新算法在迭代过程中不用计算导数，且二阶收敛。数值试验表明，该算法具有较高的精度和较大的初值选择范围。

| Abstract: | Based on the improved Atiken iterative method and dimidiate method,a new algorithm of searching the root of nonlinear equation is given,the simulation results show that if using the new algorithm,the convergence speed is faster than the improved Atiken iterative method.Besides,the selective range of the initial value is broaden. |
