是英語名詞的複數形式,音標為美式[ʌnˈsɜːrtnti]/英式[ʌnˈsɜːtnti],核心釋義為“不確定性”或“不確定因素”。該詞源自前綴(否定)與詞根(確定)的組合,通過後綴構成複數形式,專指難以預測或量化模糊的變數狀態。
該詞自20世紀起廣泛套用於數學、統計學及社會科學領域,尤其在經濟分析、風險評估和政策制定中成為關鍵術語。其專業用法包括“參數不確定”(parameter uncertainties)、“系統誤差”(systematic uncertainties)等科學測量概念,以及“經濟不確定性”(economic uncertainties)等社會經濟指標。在量子物理領域衍生出“測不準原理”(uncertainty principle),在工程學中形成“不確定性分析”(uncertainty analysis)等專業術語。作為《劍橋詞典》《牛津詞典》等權威辭書收錄的基礎辭彙,其複數形式獨立構成詞條,被同義詞替代使用。
