目的 研究低温环境下紫外线照射进行空气消毒的有效时间。方法 确定门诊流产室（Ⅱ类环境）和门诊外科诊室（Ⅲ类环境）各2间为本研究对象，在室温＜20℃，相对湿度＜60％环境条件下，分为30、60、90、120 min 4个试验时间段，每个时间段实验样本30个。按卫生部2002年版消毒技术规范要求进行实验。结果 试验数据显示，低温条件（室温＜20℃）下，Ⅲ类环境消毒30 min与消毒60 min检出菌落数比较，差异有统计学意义(t=2.603,P＜0.05),Ⅱ类环境消毒120 min后检出菌落数大于消毒90 min，差异有统计学意义(t=0.373,P＜0.05)外，其他各消毒时间段Ⅱ、Ⅲ类环境空气中细菌检出数比较，差异无统计学意义(x2 =0.517,P＞0.05),各时间段细菌监测合格数比较，差异无统计学意义(P＞0.05)。结论 紫外线在低温环境下（室内温度＜20℃）进行空气消毒的有效消毒时间是30 ～60 min。

Objective To research for the effective time of ultraviolet germicidal irradiation for air disinfection in a low temperature. Methods A clinic abortion rooms (type Ⅱ environment) and a clinic surgery diagnosis rooms(type Ⅲ environment) were selected randomly for our experiment and sampled in them after 30 min, 60 min, 90 min and 120 min disinfection, both in the temperature below 20 ℃ and of the relative humidity below 60％. Every sampling involved 30 air samples and all the experiment procedures were in accordance with the technical standard for disinfection established by Ministry of Health in 2002. Results As our data showed, in a low temperature (ambient temperature ＜ 20 ℃), there was difference in colony count after 30 min and 60 min disinfection in the type Ⅲ environment (t = 2. 603, P ＜ 0. 05), and there was difference in colony count after 90 min and 120 min disinfection in the type Ⅱ (t = 0. 373, P ＜ 0. 05), there was no statistically different in other time between the two groups, did the colony count of air bacterial have clear statistical difference (X2 = 0. 517, P ＞ 0. 05), the eligible count in each time was similar (P ＞ 0. 05).Conclusions The effective time of ultraviolet germicidal irradiation for air disinfection in a low temperature (ambient temperature ＜ 20 ℃) is about 30 to 60 minutes.
