我们通常指的煤气,实际上就是煤炭没有燃燒完全所产生的一氧化碳气,它是一种无色、无臭、无味(混有杂质的可能有臭味)的气体,所以容易令人疏忽。它能危害人,主要是因为它能妨碍人对于氧气的摄取,造成医学上所說的“缺氧証”。人活着,需要不时地把外面的空气吸到肺里,这样才能保証生活必不可少的氧气的供給。全身各个細胞都必須有氧才能燃燒养枓,发放能量,进行新陈代謝,維持每个細胞与整个人体的正常生活活动。一个人在平靜的时候,每小时差不多要呼吸130升氧气。打一个比方说:人身体上的血管就象交通运输线,血液就象交通工具,氧气就象各种物資,氧气涵过肺胞透入血中,与紅血球中的血紅素結合,然后这些运載氧分子的“紅血素”列車,便 The gas we normally refer to is actually the carbon monoxide gas produced by the unburned coal. It is a colorless, odorless, odorless (odorous, odorous) gas that can be easily neglected. It can harm people, mainly because it can hinder people’s intake of oxygen, resulting in medically called “hypoxia card.” People are alive and need to breathe the outside air into the lungs from time to time, so as to ensure the supply of essential oxygen to life. All cells in the body must be aerobic to burn Yang, energy distribution, metabolism, to maintain the normal life activities of each cell and the entire human body. When you are calm, you breathe about 130 liters of oxygen every hour. For example, a human body’s blood vessels are like transportation lines. Blood is like a means of transportation. Oxygen is like any kind of material. Oxygen passes through the lungs and penetrates the blood and binds to the heme in red blood cells. Carry oxygen molecules “red blood” train, then
