摘　　要：在救生舱内长时间等待救援过程中,避难人员能够适应的的氧气体积分数存在一个较宽的范围,如果氧分压过低会引起各种缺氧反应,精神效能受到影响;氧分压过高则不能保证正常新陈代谢,会导致氧中毒等现象。通过测试不同环境温度下受试人员心率与氧气体积分数的关系,得到人体氧含量生理舒适度的范围。同时参照ASHRAE七级标度法,设计了新的非对称五标度舒适度评价体系,采用调查问卷方式得到受试人员对氧含量的舒适度投票,通过两种方法确定了人体在救生舱内长时间生存时氧气体积分数的上、下限分别为18.5%和22.5%。通过对舒适度曲线的拟合,得到人体舒适度感觉与环境中氧气体积分数的依变关系。In the process of long waiting for rescue in refuge chamber,evacuation personnel can adapt to a wide range of oxygen volume fraction. If the oxygen partial pressure is too low,all kinds of hypoxic reactions can be caused,such as the influence on mental efficiency. And the high oxygen partial pressure,which can lead to oxygen toxicity,can not guarantee people's normal metabolism. Based on the tests that the relationship of heart rate and oxygen volume fraction at different ambient temperatures,the physiological comfort range of oxygen content in human body was obtained.And refer to the ASHRAE seven-point scale method,a new asymmetric five scale comfort degree evaluation system was designed. Meanwhile by the form of the questionnaire,votes of the comfort degree of oxygen content in refuge chamber were got from the subjects. By the above-mentioned two methods,the upper and lower oxygen volume fractions respectively are 18. 5% and 22. 5% during long-time survival in refuge chamber. Finally through the comfort curve fitting,the relationship between the human body sensory comfort and oxygen volume fraction was obtained.
