避难硐室内人的呼吸生理学基础在单纯居留人员的地下避难硐室中,如果人员众多而空间有限,人体的呼吸,特别是有生产任务的人员的呼吸对空气成分影响很大。例如,在地下工程中,劳动时人体呼出的废气中氧含量只占16．4%,氮仍占79%左右,而二氧化碳却增加到4．1%以上,并充满着水蒸气。人体呼吸量、耗氧量及其中 Evacuation Cave Indoor Respiratory Physiology Basis In the underground evacuation chamber of a single resident, if the space is limited due to the large number of personnel, the respiration of the human body, especially those with production tasks, has a great influence on the air composition. For example, in underground works, the oxygen content of exhaled gases exhaled by the human body during work only accounts for 16.4%, nitrogen still accounts for about 79%, and carbon dioxide has increased to 4.1% and is full of water vapor. Body breathing, oxygen consumption and among them
