1.绪言空气不仅是人呼吸不可缺少的,而且是具有一定助燃能力的气体。在工业上,空气作为不会爆炸的气体具有很多用途。很早以前,为了传递能量,供应呼吸,帮助燃烧等,人们就把空气压缩而加以利用了。在欧洲的煤矿里,由于狭小的坑道内发生一种可燃性甲烷气体,它是一种引火源,最怕遇到感应生电事故,因此,作为能源的压缩空气已处在比电气更受欢迎的时代。而且,从起动与搬运凿岩机(风镐)用的空气机车和空气发电灯中排出的空气,不

Moreover, the air discharged from the air locomotive and the air power light for starting and transporting rock drills (picks) does not
