摘 要：測量的目的就是為了得到更準(zhǔn)確的測量值，但在實(shí)際測量時，由于受多方面因素的影響，使得測量值與實(shí)際值之間必定存在誤差，該誤差即為測量準(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量準(zhǔn)確度的方法與步驟。
關(guān)鍵詞：測量準(zhǔn)確度 測量精密度 系統(tǒng)誤差 隨機(jī)誤差 粗大誤差 剩余誤差 算術(shù)平均值

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
