In this paper we suggest and analyze a new iterative method for solving nonlinear equation f（x） =0 by rewriting the given nonlinear equation as a coupled system of equations and using the Taylor series. It is shown that this iterative method with fourth - order is more efficient than Newton＇ s methods and He＇ s method by some numerical results.%通过泰勒级数将非线性方程f（x）=0改写为耦合系统，给出并证明求解非线性方程的一种新的四阶迭代方法。数值例子表明，此四阶迭代法比牛顿迭代法和何给出的迭代方法有效。
