air pressure

air pressure的音标是[ˈeəpreɪʃəs]；基本翻译是“气压”；速记技巧是：air“空气”+ pressure“压力”。

Air pressure的英文词源可以追溯到拉丁语中的“aere”和“pulsare”，意为“空气”和“推动”。这个词在英语中经历了许多变化形式，包括“atmospheric pressure”、“barometric pressure”、“air pressure”等。

英文小作文：

Air pressure is a crucial factor in our daily lives and in space exploration. It affects our environment, our health, and even our ability to perform certain tasks. Atmospheric pressure changes with altitude, weather, and other factors, making it necessary to monitor and adjust air pressure constantly. In space, air pressure is maintained by artificial means, such as air pumps and regulators, ensuring that astronauts can work and live in a safe and comfortable environment. On the other hand, underwater, air pressure is necessary to protect divers from the extreme low air pressure of the sea depths. Understanding and managing air pressure is crucial for our daily lives and for future space exploration missions.
