名词 n.
  1. The quality of being respirable; respirability. uncountable
    — The usual method of testing the respirableness of air suspected to be contaminated with carbon dioxide is to lower a lighted candle into it; if the candle goes out the atmosphere is poisonous; if it continues to burn, however, the air is not necessarily harmless, as a candle will burn in an atmosphere that is dangerous to life.

词源

From respirable + -ness.
