地下设施在通风不良的情况下,由于人的呼吸、衣服的吸附和烟尘可以引起空气中离子数急剧减少。已有许多实验证明,轻阴离子对改善人体机能状态,减少疲劳和提高工作效率能够起良好的积极作用,而阳离子与它相反会起不良的消极作用。本试验目的是通过地下环境空气离子的检测和观察吸入负离子对人体生理功能的影响,为探索地下环境空气离子的分布和人工负离子发生器用于地下环境对人体保健作用提供依据。 Underground facilities In the case of poor ventilation, due to human breathing, clothing adsorption and smoke can cause a sharp reduction in the number of ions in the air. Many experiments have shown that light anions can play a positive role in improving human functional status, reducing fatigue and improving work efficiency, whereas cations, in contrast, can have an adverse negative effect. The purpose of this experiment is to detect and observe the influence of inhaled anions on the physiological functions of the human body by measuring the air ions in the underground environment and provide the basis for exploring the distribution of air ions in the underground environment and the health effects of the artificial anion generator for the underground environment.
