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．
