The temperature is sensed by a thermocouple located in the vapour space.
该温度由位于蒸气空间的热电偶所测出。
Just a fortnight ago, astronomers using the Hubble space telescope identified water vapour in the atmosphere of an exoplanet, albeit a gaseous exoplanet some 150 light years away.
就在两周前,天文学家使用哈勃太空望远镜,在一颗外星行星的大气中确定了水蒸气的存在,尽管该行星离我们有大约150光年。
The next logical step would be a space telescope capable of picking up the chemical signatures of life, including the presence of oxygen, water vapour and carbon dioxide.
理论上讲下一步应该是发射能够观测化学信号的望远镜,以为生命的存在提供依据。有价值的信号包括氧气、水蒸汽和二氧化碳。
