为了解环境因素对紫外线灯输出强度的影响。我们对本医院11支紫外线灯进行了调查。紫外线灯输出强度用军事医学科学院微生物流行病研究所提供的微型紫外线强度计,在灯管垂直1 m处测量。开灯后5分钟读数,同时记录环境温度和相对湿度。每日测量一次,共测量23次。调查结果,紫外线灯管表面附着的灰尘经用酒精棉球擦拭后平均可提高输出强度6.29μW/cm~2,其95％的可信区间为5.13
To understand the environmental factors on the UV lamp output intensity. We conducted a survey of 11 UV lamps in our hospital. UV lamp output intensity Micro-UV intensity meter provided by the Institute of Microbiology and Epidemiology, Academy of Military Medical Sciences was measured at 1 m vertical to the lamp. Five minutes after turning on the lights, record the ambient temperature and relative humidity. A daily measurement, a total of 23 measurements. The survey results show that the dust attached to the surface of the UV lamp can increase the output intensity by an average of 6.29μW / cm ~ 2 after wiping with alcohol cotton balls, and the 95% confidence interval is 5.13
