摘 要：測(cè)量的目的就是為了得到更準(zhǔn)確的測(cè)量值，但在實(shí)際測(cè)量時(shí)，由于受多方面因素的影響，使得測(cè)量值與實(shí)際值之間必定存在誤差，該誤差即為測(cè)量準(zhǔn)確度。本文從誤差產(chǎn)生的原因、誤差的性質(zhì)特點(diǎn)，著重從減小系統(tǒng)誤差的角度分析討論提高測(cè)量準(zhǔn)確度的方法與步驟。

Analysis of methods to improve measurement accuracy

Song Yuexiao，Wang Ransheng

Abstract：The purpose of measurement is to get more accurate measurement values. Due to the influence of many factors， there must be an error between the measured value and the actual value in the actual measurement， which is called the measurement accuracy. The paper proposes methods and steps to improve the measurement accuracy from the causes and the characteristics of errors as to reduce the systematic errors.

Key words：measurement accuracy， measurement precision， systematic error， random error， gross error， residual error， arithmetic mean
