摘　　要：Effects of hypoxia on learning-memory function and swimming capability of rat were studied and the ergonomics under hypoxic condition was also evaluated from the biological point of view.Three modes of hypoxia were designed and plots of oxygen concentration versus time for each group in hypoxic environment were produced.Results showed that the effects of hypoxia on learning-memory function and swimming capability were related with the time and strength of hypoxia.It had nothing to do with the individual difference of rat models.10% O2 long-term intermittent anamorphosis hypoxia could improve the swimming capability of rat model significantly.Stimulating with proper level of hypoxia,carbon dioxide could improve ergonomics in airtight hypoxia environment.Under hypoxia condition,from the ergonomic point of view,6% O2 is the important threshold and might belong in critical region.Effects of hypoxia on learning-memory function and swimming capability of rat were studied and the ergonomics under hypoxic condition was also evaluated from the biological point of view.Three modes of hypoxia were designed and plots of oxygen concentration versus time for each group in hypoxic environment were produced.Results showed that the effects of hypoxia on learning-memory function and swimming capability were related with the time and strength of hypoxia.It had nothing to do with the individual difference of rat models.10% O2 long-term intermittent anamorphosis hypoxia could improve the swimming capability of rat model significantly.Stimulating with proper level of hypoxia,carbon dioxide could improve ergonomics in airtight hypoxia environment.Under hypoxia condition,from the ergonomic point of view,6% O2 is the important threshold and might belong in critical region.
