英[hɒt'eə] 美[hɒt'eə]
  • adj.热空气的
名词 hot air:
  1. air that has been heated and tends to rise

  2. loud and confused and empty talk

    用作形容词 (adj.)
    1. As the hot air exiting the supercharger encounters the cooler pipes, it also cools down.
      当热空气离开机械增压机进入冷却管,就能降低空气的温度。
    2. And if you happen to be wearing a robe, all that movement of the warm air creates a breeze that sucks up cooler air from the bottom of the robe and pushes it out the top.
      所以如果你碰巧穿着个长袍,热空气的运动就形成了一股小气流,把冷空气从袍子外面吸进来,再把它们慢慢推到顶部。
