摘　　要：火花源发射光谱仪测定钢筋中钒、铌含量,测量不确定度主要来源于样品测定重复性、类型标样、工作曲线、高低标校正、环境的温度、仪器稳定性及仪器分辨力。依据JJF1059-1999对测量结果的不确定度进行了评定和表述,对各个不确定度分量进行了计算和合成。The uncertainty in the measurement of V and Nb contents in HRB 500 steel bar by spark emission spectrometry was evaluated. The uncertainty originated from measurement repeatability, reference materials, standard curve, calibration, enviromental temperature and stability and resolution of apparatus. The components of uncertainty were calculated and combined. The mathematical formula for calculating the uncertainty were given.
