摘　　要：对Saltzman法测定环境空气中二氧化氮含量的不确定度进行评定,通过对测量过程重复性、所用的计量玻璃量器、标准溶液的浓度、标准曲线的绘制、采样体积和吸收液体积等影响测定结果的不确定度分量进行分析,找出影响测量结果的关键因素,对进一步优化测试方法,提高实验的准确度有重要意义。The uncertainty of nitrogen dioxide content in ambient air detected by Saltzman method was evamateo. Refolding process by measuring, using the measurement container, the concentration of standard solution, drawing standard curve, the sampling volume and the absorption solution volume of uncertainty affecting the measurement results of component analysis to indentify the key factors affected the measurement results. It would provide a significance of guidance to further optimize the detection method and improve the accuracy of tests.
