目的　为了更好的了解各种因素对紫外线杀菌效果的影响，我们在净化间进行了紫外线对不同标准菌的消毒实验。方法　在不同条件下使用强度为100 μW*cm-2*s-1的紫外线灯对净化间喷雾的标准菌进行照射。结果　温度、湿度、紫外线强度、照射方式和电扇吹风与否、以及不同微生物对紫外线的消毒效果均有显著影响，温度对紫外线杀灭率影响最大；在相同条件下紫外线杀灭白色葡萄球菌的效果最好，大肠杆菌其次，枯草杆菌最差。结论　用高强度低臭氧紫外线灯进行空气消毒的方法是可靠、安全、实用和可行的。

Objective　To investigate the effect of various fa ctors on disinfection efficacy of ultraviolet ray. Methods　The germicidal exper iment was carried out in a purified chamber. Standard bacteria sprayed in the p urified chamber was irradiated by using an 100 μw*cm-2*s-1ultrav iolet lamp under different c onditions. Results　The disinfection efficacy showed correlation with tempe rature, humidity, intensity, way of radiation, electric fan running or not and different microorganisms, among which temperature showed the strongest effect on killing rate. Under the same condition, the efficacy of ultraviolet l amp in killing staphylococcus albus is superior to that in killing escheri chia coli, and the efficacy of killing the spore of bacillus subtilis is the l owest. Conclusions　The way of air disinfection by a high intensity and low ozone ultraviolet lamp irradiation is reliable, safe, practical and feasi ble.
