Abstract: Abstract: Objective To study the disinfection effect of high-energy xenon light transfer window in the air and object surface bacteria． Method The bacterial suspensions were prepared from the standard strains of Staphylococcus aureus，Bacillus subtilis and Escherichia coli and to simulate the surface bacteria on coated blood plate． The air drop bacteria were cultured on common nutrient agar plate． The experimental group was irradiated separately by xenon light transmission windows and ultraviolet irradiation in 3 min，and then was placed in a constant temperature of 37 ℃ with control group for incubating for 24—48 h，then calculated the killing rate．Ｒesult The average killing rate reached to 93. 2% after irradiation by the xenon light on the bacteria suspension coating liquid blood plate; the average killing rate reached to 99. 1% in air bacteria after irradiation by the xenon light irradiation in 3min． The killing rate of two kinds of plate after 3 min ultraviolet irradiation was less than 50%． Conclusion Xenon light transfer window could efficiently and quickly kill the bacteria on the object surface and in the air，average killing rate could reach to 95%，xenon light transmission window would be the replacement of the routine transfer window．

摘要： 摘要: 目的研究高能氙光传递窗对空气中和物品表面细菌的消毒效果。方法分别用标准菌株金黄色葡萄球菌、枯草芽孢杆菌和大肠埃希菌制备细菌悬液并涂布血平板，模拟物品表面细菌; 用普通营养琼脂平板培养空气落下菌。将两种平板经氙光传递窗和紫外线分别照射3 min 后，与对照组均放置于37℃恒温培养箱24—48 h，计算杀菌率。结果涂布于血平板的细菌悬液，经氙光照射3 min 后，平均杀菌率达到93. 2%; 空气落下菌经氙光照射3 min后，平均杀菌率达到99. 1%。两种平板经紫外线照射3 min 后的杀菌率不到50%。结论氙光传递窗能够高效、快速杀灭物品表面和空气中的细菌，平均杀菌率达到95%以上，氙光传递窗有可能成为常规传递窗的替代品。
