平行双样对大气二氧化硫采样样品进行质量控制的应用研究

Application study of parallel double sample in quality control for air SO 2 collected

通过对大气二氧化硫采样平行双样相对偏差变化规律的分析，证明了用平行双样控制大气二氧化硫采样样品的质量是可行的，并确定了平行双样相对偏差的控制指标。

The changes law of velative deviation in parallel double sample for air SO 2 collected was analysed in this paper It is feasible that parallel double sample controls the quality of air SO 2 collected The control target of relative deviation in parallel double sample was defined It was proved dependable basis for the quality control of air SO 2 collected
