摘要
本文根据产生误差的原因,提出了将测量误差分解成一系列误差项的方法。这些误差项的估计值都可以用理论和实验方法加以确定。文中按产生误差的原因,将目前广为应用的基本误差,附加误差,方法误差等概念汇集在一起,给以确切的定义。本文的分解方法有着理论上的严密性及清晰的条理性,可以减少误差分析中误差项的遗漏和重复。用这样分解的误差项有着简单的相关性,便于误差综合。
This paper introduces a method of dividing measuring error intosome terms in accordance with the reasons causing the error.The evaluatingvalue of the error terms can be determined by experiments or theoretically.This paper studies the relationship of basic error and accessory errors and me-thod error which are used widely,and gives the exact definitions to them.Onthe theory,this method of dividing measuring error has rigorous and clear re-gularity.It reduces the remainder and redundant of errors.Furthermore,the error terms divided by this method have simple interrelations,thereforethey are of benefit to synthesis.They can be recounted as following:A.The errors of measuring device:a.The errors caused by gauges and ins-truments which make up the measuring device,b.The accessory errors of themeasuring device caused by deviations of all operatiug condition parameters torated value.c.The method errors of the measuring device caused by basicdeviations of structural parameters.B.The instable errors of measured object:a.The errors caused by theiustablity of the measured object's basic error in time.b.The variant valueof accessory errors caused by the variantions of operating condition of themeasured object.
