摘　　要：本文提出一种简单有效的误差预报方法,该方法与传统的近似计算方法有很大不同,它是以误差分析为切入点,再由此确立各误差之间的关系,建立数学模型,用误差来预报误差,从而达到减小误差范围,提高计算精度的目的。In this paper,an idea of error prediction for improving computational accuracy is put forward and elementory study has been done.This idea is quite different from the traditional approximate numerical computional scheme.The first step of this idea is error analysis,then the mathematical model based on the relations among the errors is established,and a preciser error can be predicted from the known ones through this model,so the error range of computed result will be reduced and the computational accuracy improved.

关 键 词：误差分析 误差预报 计算精度
