摘要:
微分法计算误差是一种近似算法,存在方法上的误差。本文剖析了方法误差的实质;对机械制造中常见的几种函数的方法相对误差作了分析,并获得其基本观律;对微分法在机械制造中的准确性作了基本的概括;最后提出误差中心移正法,可显著提高微分法的准确性和适用性。
Abstract:
Differentiation as an approximate method for error evaluation has an error in method itself. In this article the essential parameters of the error in method and the relative error in method of several common functions in machine manufacturing are analysed as well as some basic formulas are achieved. It reveals the accuracy of differentiation in machine manufacturing fundamentally and shows the method for shifting the distribution center of error, which significantly increases the accuracy and applicability of the differentiation method.
