【摘要】 为探讨撞击法监测室内空气微生物的稳定性 ,使用 JWL - B型多功能空气微生物监测仪对招待所、文化娱乐场所、理发美容室中 11个场所分别进行 2 min、 4min监测 ,结果显示 :在同一个环境下采样时间不论 2 min还是 4min,其测定值差异无显著性 (t=1.85 4,P>0 .0 5 ) ,说明用撞击法监测室内空气微生物在所测定的时间内有较好的稳定性更多还原

【Abstract】 To explore the stability of impact assay for determination of microorganism in indoor air,the compa- risons of continued sampling times of 2-minute and 4-minute for monitoring on microorganism of indoor air were carried out with JWL-ⅡB multi-functiom air microorganison monitor in 11 hotels, public places of entertainment, barbar shops and beauty shops The results showed that, under a same environmental condition, there was no significant differences between the data obtained by 2-minute monitoring and 4-minute monitoring (t=1854, P>005) It indicated that impact assay presented very good stability in detecting the microorganism of indoor air within certain detecting duration更多还原
