ON RELATIONS BETWEEN THE MODIFIED-ITERATIVE METHOD AND CHIEN’S PERTURBATION SOLUTION

摘要

In this paper.we gave analytical formulas of characteristic relation of circular plale insolving high-order solutions of modified-iterative method,which reduces the calculatingquantities of the method.Having deduced the relations between the modified-iterativemethod and Chien’s perturbation solution.we obtained the conclusion that the convergentregions of the two methode are the same.
