摘　　要：在土壤总氰化物的测定中,异烟酸-吡唑啉酮分光光度法是普遍使用的一种方法,文章以此方法为基础开展数据分析,开展不确定度评定。通过分析土壤中总氰化物测定的全过程,用测定不确定度评定与表示的方法,建立不确定度的数学模型,得出有效准确的数学表达式,找出每项不确定度分量的来源,确定扩展不确定度结果,体现准确性和可靠性。The isonicotinic acid-pyrazolone spectrophotometric method is widely used in the determination of total cyanide in soil.This study was based on this method to conduct data analysis and perform uncertainty evaluation.The entire process of total cyanide determination in soil was analyzed,and a mathematical model for uncertainty was established using methods for evaluating and expressing measurement uncertainty.An effective and accurate mathematical expression was developed,identifying the sources of each uncertainty component and determining the expanded uncertainty results,thus reflecting accuracy and reliability.
