测量结果或测量装置误差分析的建议方法

A Suggestive Method to Analyse the Error of Measuring Result or Measuring Instrument

本文对测量结果或测量装置的误差分析提出建议方法:1.按误差产生原因将误差Δy 分解成一系列误差项Δz_t=C_(θt)Δθ_t。2.估计出各误差项Δz_t 的极限值[Δz_t]并按平方相加法则由[Δz_t]综合出误差Δy 的极限值[Δy]。3.按[Δy]的数值大小对测量装置或测量数据进行准确度分级。这方法有着理论上的严密性和清晰的条理性,不包含难以实现的人为假设,因此便于实行。

This paper introduces a suggestive method to analyse the error of measuring instrument.It can be recounted as following:1:In accordance with the reasons causing the error,we divide the error △y into some terms:A△z_(?)=C_θt△θ_t(t=1-ω).2:We estimate the limiting error[△z_(?)]of theevery term error △Z_(?) for all terms.Then the limiting error[△y]of △y issynthesized by all[△z_(?)] in the usage sguare additional law.3:Finally,the ac-curacy of the measuring result or the measuring instrument is classified acco-rding to the value of[△y].This method has rigorous and clear regularity onthe theory.It does not contain any personal supposition which is difficult torealize.Therefore,it is convenient for execution.
