摘要
可吸入颗粒物污染是大气中常见的污染因子之一,其测定方法主要为β-射线法。为确保该方法测定结果的可信度,本文对BAM-1020型β-射线自动测尘仪校准的不确定度进行了分析,找出了影响不确定度的因素,并对不确定度进行了评定,评定结果如实反映了测量的置信度和准确度。
PM10 was one of the main pollution factors in air pollution and was usually measured by using β- ray method. The measuring uncertainty of BAM - 1020 β - ray auto - measuring dust instrument was assessed. The factors affecting the uncertainty were evaluated and the results could accurately reflect the measurement confidence and accuracy.
