摘　　要：本文对靛蓝二磺酸钠分光光度法测定某工作场所空气中臭氧浓度的不确定度进行了评定。结果表明,臭氧浓度的扩展不确定度为U=0.16 mg/m^(3),影响臭氧浓度测定不确定度的主要因素是样品采集时所引入的不确定度。In this paper,the uncertainty of the determination of ozone concentration in the air of a workplace by spectrophotometry with sodium indigo disulfonate was evaluated.The results show that the expanded uncertainty of ozone concentration is U=0.16 mg/m^(3),and the main factor affecting the uncertainty of ozone concentration measurement is the uncertainty introduced during sample collection.
