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 ) 。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
