Abstract: We simulated the air distribution at the statuses of empty, transverse and verti cal arrangement of animal cage in SPF animal room. We also analyzed the idiograp hic characters of those kinds of air distribution and compared the good and bad among them. The author simulated and analyzed the relation between the air distr ibution and contamination distribution in the animal room. They reached the conc lusion and gave some advises about how to optimize the air distribution in the l aboratory animal room.
