提高測量準確度的方法分析

宋悅孝　王然升

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

關鍵詞：測量準確度 測量精密度 系統誤差 隨機誤差 粗大誤差 剩余誤差 算術平均值

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
