摘　　要：针对臭气浓度的标准分析方法——三点比较式臭袋法,在分析过程中引入"无法辨别"选项,并建议稀释倍数由标准限值确定。经实际案例验证,采用改进后的方法,分析结果更接近现场的真实状况,从而提高了嗅辨结果的准确性,并减轻了嗅辨员的嗅觉疲劳。Aiming at standard odor concentration analysis method, triangle comparative odor bag method, the ＂incapable discrimination＂ item was quoted. It is advised that the dilution times should be determined by standard limit value. The optimized method was verified by actual cases that the results were closer to the real conditions on-site. The accuracy of olfactory debate was improved and olfactory tiring was avoided.
