breather mask 中文意思是什麼
breather mask
解釋
呼吸面罩-
Consider a space station where air must be manufactured at great cost : charging each breather per liter of air may be fair, but wearing the metered gas mask all day and all night is intolerable even if everyone can afford to pay the air bill
設想在一個需要昂貴費用製造空氣的太空站里:向呼吸者收取每升空氣的費用是合理的,但是如果必須整日整夜地配戴計量呼吸量的面具,那將是無法忍受的,即使能夠支付空氣賬單。
