中文摘要：
重新构造L-M迭代参数，来求解非线性方程组P（x）=0．在算法中，当试探步不成功时，采取新的非精确线搜索技术获得下一个迭代点．在适当假设条件下，证明了该算法具有全局收敛性．数值实验表明该算法是有效的．
英文摘要：
The author provides a new L-M iterative parameter, is a real parameter for solving a system of singular nonlinear equations F（x） = 0. The algorithm performs a new inexact line search to find a new itera tion point if a trial step is not accepted. Global convergence of this new method are proved under mild conditions. Some numerical results are reported, which shows that the algorithm is quite effec tive.
