"測量不确定度（uncertainty of measurement）"是計量學中的核心概念，指對測量結果可信程度的科學量化表征。它反映了測量值可能存在的分散區間，其本質是對被測量真值所處範圍的合理估計。根據國際标準化組織（ISO）發布的《測量不确定度表示指南》（GUM），該術語的完整定義包含三個核心要素：
定義内涵
測量不确定度由多個分量組成，既包含系統效應（如儀器校準偏差）引起的分量，也包含隨機效應（如環境波動）導緻的分量。國際計量局（BIPM）強調，這不僅是簡單的誤差範圍，而是采用概率統計方法評估的置信區間。
來源分類
根據中國國家計量技術規範JJF 1059，不确定度來源可分為六類：測量方法缺陷、儀器分辨率限制、标準物質偏差、環境條件波動、人員操作差異以及數學模型近似。其中儀器校準證書提供的不确定度信息最具權威參考價值。
标準化框架
ISO/IEC 17025認證體系要求檢測實驗室必須建立不确定度評估程式。典型評估方法包含A類評定（實驗标準偏差）和B類評定（非統計方法），二者通過方差合成原則形成擴展不确定度。美國國家标準與技術研究院（NIST）特别指出，包含因子k=2時對應的置信概率約為95%。
該概念在質量控制、醫療檢測、環境監測等領域具有關鍵作用。例如在醫藥行業，世界衛生組織（WHO）規定疫苗效力測量的擴展不确定度必須控制在±5%以内。歐盟計量組織EURAMET的研究表明，超過80%的工業質量争議源于不确定度評估不充分。
測量不确定度（Uncertainty of Measurement）是科學、工程和質量控制領域中的核心概念，用于量化測量結果的可靠性。以下從定義、組成、應用及意義等方面詳細解釋：
測量不确定度表示對被測物理量真實值存在範圍的合理估計，通常以一定置信概率給出。例如，若測量結果為 ( 10.0 , text{mm} pm 0.2 , text{mm} )，則真實值有較高概率落在 ( 9.8 , text{mm} ) 到 ( 10.2 , text{mm} ) 之間。
不确定度通常分為兩類：
總不确定度通過合成兩者得出（如方和根法）： $$ u_{text{total}} = sqrt{u_A + u_B} $$
測量不确定度幫助使用者判斷數據是否適用于特定場景，避免因過度信任單一測量值導緻決策失誤。國際标準（如ISO/IEC指南98-3）已将其作為質量體系的核心要求。
