Changsha University of Science ＆ Technology , Changsha , Hunan 410007, China Abstract:According to the method for analysis of acid valence of edible oil and study on uncertainty in measurement coming from analysis procedure, a mathematical model of the result was founded. The independent uncertainty, standard uncertainty and expanded uncertainty were obtained. The method established in this paper can be used to evaluate uncertainty in measurement of acid valence of edible oil.[著者文摘]
