摘　　要：对水中氰化物测定中的不确定度进行分析,根据建立的数学模型,找出影响不确定度的因素,运用测定不确定度评定与表示的理论,建立了有效的数学式。根据数学式,通过实验测定标准样品中氰化物的扩展不确定度结果,如实反映测定的客观性和准确性。In this paper,the uncertainty of cyanide in water is analysed,and according to the established mathematical model,the factors that affect the uncertainty are identified.Using the theory of evaluation and determination of uncertainty an effective mathe matical expression is set up.According to which the uncertainty of cyanide expansion in the standard samples is determined by tests,which accurately reflects the objectivity and accuracy of the determination.
