如何处理N─R迭代过程中的收敛问题

How to Deal with the Convergence Problem in the Process of N-R Iteration

本文就电子线路ＣＡＤ中的非线性直流分析所采用的改善Ｎ－Ｒ迭代法，从其必要性到具体的算法作一分析，并指出各种方法适用范围。

With regard to the method of improving N-Riteration used in the analysis of non-lin-ear DC in the electric circuit CAD,this paper,for one thing,analyzes its necessity and detailedcalculation;and for another.points out the range of applications of each method.
