据英国《每日邮报》报道,作为一名宇航员会有很多事情需要担心,例如在执行任务时的安全性,狭小的空间易导致幽闭、恐惧症状和冒险旅途中的孤独寂寞。但是现在他们又有一件事情需要担心,那就是肠胃气胀。人类产生两种可燃气体——氢和甲烷,这些气体聚集在封闭空间时就能点燃,这对生活在狭小太空船里的宇航员构成威胁。 According to the British “Daily Mail” reported that as an astronaut there are many things to worry about, such as the safety of the mission, narrow space can easily lead to claustrophobia, fear symptoms and adventure loneliness. But now they have one more thing to worry about, that is flatulence. Humans produce two kinds of combustible gases, hydrogen and methane, which can ignite when they accumulate in confined spaces, posing a threat to astronauts living in small spacecraft.
