室内缺氧程度对数评价方法

Logarithmic Evaluation Index of Indoor Hypoxia Degree

在高海拔地区,影响人体舒适度的因素除了声、光、热和空气品质外,空气中的氧气浓度也是影响人体舒适度的重要因素。为了评价供氧室的供氧效果,采用分贝概念评价室内缺氧程度,提出了评价室内缺氧程度的对数指标I_(d O2),并在青藏铁路沿线站点进行问卷调查,分析了I_(d O2)与高原反应风险关系。

In high altitude areas,besides sound,light,thermal environment and air quality,oxygen concentration in the air is also an important factor affecting human comfort.In order to evaluate the oxygen supply effect of oxygen enriched chamber,the method of using dB concept to evaluate the indoor hypoxia degree,and the logarithmic index I_(d O2)was put forward.In addition,a questionnaire survey at stations along the Qinghai-Tibet Railway was conducted to analyze the relationship between I_(d O2)and the risk of altitude reaction.
