通过把铈铝玻璃放置在25吉帕压力下——大约250000倍的标准大气压——这个研究小组制成了单晶体。
The Xoom also features a gyroscope as well as a barometer for measuring the atmospheric pressure while the HP PalmPad has a gyro.
Xoom还提供陀螺仪，和测量大气压的晴雨表，当然HPPalmPad上也有陀螺仪。
The atmospheric pressure and low temperatures found in the deep ocean environment should keep the liquid CO2 negatively buoyant , meaning it will sink rather than float.
大气压力和已经被发现的深海里的低温环境应该会保持CO2有负浮力，也就是它会在水里下沉而不是上浮。
At this altitude, atmospheric pressure is considerably less than at sea level, so the carbonated bubbles in beer escape more rapidly.
在这个海拔上，大气压远远低于海平面，所以啤酒里的气泡会被更快地释放出来。
To get a feel for what this would mean, bear in mind that the amount of oxygen in a given volume of air changes with atmospheric pressure, and the local pressure changes with the weather.
要了解这将意味着什么？给定体积的空气中的含氧量是随着大气压变化而变化的，而当地的气压又是随天气变化的。
During the ascent the balloon is constantly widening because of the decrease of atmospheric pressure, and at a certain height it will inevitably burst.
在上升的过程中，随着气压的降低，气球不断膨胀，到一定的高度，气球就会爆破。
And first of all, there's just atmospheric pressure.
首先，这里有大气压。
Atmospheric pressure decreases with increase in altitude and so does the density of the atmosphere.
大气压力随高度增加而降低，大气密度也随着高度增加而降低。
This decreases the quantity of air in that area, and therefore decreases the atmospheric pressure.
这使得该地区的空气质量减小，因此减少了大气压强。
Atmospheric pressure is the weight of all that air against the surface of the earth.
大气压就是压在地球表面上的所有空气的重量。
If we did not have atmospheric pressure.
假如我们没有大气压力。
Suwon in atmospheric pressure of water (or water) through the pipe network under pressure to the water pipes into the inside.
水原的水在大气压力（或水压）的作用下通过管网压到了进水管内。
There, the cooled air sinks, raising atmospheric pressure and suppressing rain along most of the Pacific coast, making it one of the driest regions in the world.
在那里，冷空气下沉，提高大气压力和抑制大部分沿太平洋海岸的雨，使它成为世界上最干旱的地区。
Altimeter SETTING, the adjustment of the altimeter to account for local variations in atmospheric pressure.
高度表设定，根据当地大气压力变化而对高度表所做的调整。
As altitude increases, atmospheric pressure decreases, thus exerting less "push" on the water entering the pump suction.
当海拔高度增加，大气压力减少，从而减少了作用于进入水泵的水的压力。
Pumps do not actually suck ; rather , pumps create a partial vacuum into which atmospheric pressure pushes water via the suction pipework.
水泵并不是实际的吸：更确切的说，水泵产生非完全的真空，然后大气压力将水通过吸管推进水泵中。
Pumps do not actually suck ; rather , pumps create a partial vacuum into which atmospheric pressure pushes water via the suction pipework.
水泵并不是实际的吸：更确切的说，水泵产生非完全的真空，然后大气压力将水通过吸管推进水泵中。
