1·Atmospheric pressure then pushes the piston back down the cylinder, and if anything (such as a pump) is attached to the piston, some useful work can be done.
于是，气压就会再次将活塞推至汽缸底部。而假如有诸如水泵这样的物体与活塞连接，就可以在活塞的带动下完成一些工作。
2·It's a day of nice atmospheric pressure.
那天气压很好。
3·At night the lit glass glows to indicate local weather conditions: green when weather is fair and red when atmospheric pressure drops, warning passing yachtsmen of possible stormy conditions.
到了晚上，发光的玻璃亮起，来指示当地的天气情况：天气晴朗时显示绿色，气压下降时显示红色，以此来警告通过的游艇可能会出现暴风雨的情况。
4·It has been verified by examples that the gravity used with Bouguer correction is enough accurate for atmospheric pressure measurement.
实例验证证明用布格修正法获得的重力值可以满足气压测量的准确度要求。
5·Atmospheric pressure altimeter is an important kind of aeronautical instruments, the main function of which is to offer carrier exact altitudinal information.
气压高度表是一种重要的航空仪表，其主要作用是向载体提供准确的高度数据。
