摘　　要：在基本迭代法的收敛定理及局部收敛定理的基础上,给出了局部收敛性的一个必要条件, 同时也对局部收敛定理加以推广,从而对局部收敛性有了一个更加深刻的了解。Based on the convergence theorem of fundamental iterative method and the local convergence theorem,a necessary condition of the local astringency is gived and the local convergence theorem is extended in the meantime in this paper. Whereby the local astringency is poignantly maked out.
