The air tank contains high-pressure purified air and is exactly like the tank used by a SCUBA diver.

空气瓶内装有纯净高压空气，很像 SCUBA 潜水员用的气瓶。

The main factors that affect the pressure and temperature of the chambers can be summarized as air pressure and L/D.

影响腔室压力和温度的主要因素可以概括为气压和长度直径比。

Air temperature and vapor pressure deficit were the key factors affecting transpiration.

气温和蒸气压不足是影响蒸腾作用的关键因素。

More severe cases may be treated with a CPAP machine, so named because they maintain constant positive air pressure to the wind pipe to help users breathe easy at night.

严重一点的患者可能就得用CPAP机来治疗了，人们给它取这个名字是因为它能够给气管提供稳定的空气压力，借以帮助患者在夜间呼吸。

"One of the interesting things about speech - and singing - is we go through a very complicated process so that we have an even air pressure in our lungs," Lieberman says.

“一个有趣的有关说话和唱歌的事情，是我们通过一个非常复杂的过程，使得我们我们肺里的气压保持大体均衡，”利伯曼说。
