海拔每上升1000米大气压力- - -也就是空气密度- - -会降低大概11%(虽然精确的公式比这要更复杂。)
Every 1000 metres increase in altitude reduces atmospheric pressure - and hence the density of the air - by about 11 per cent (though the precise formula is more complicated than this).
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。
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.
我们从大气压力(地球表面的空气压力)的一立方英寸氢气开始。
We will start with a cubic inch of hydrogen at atmosphere pressure (or the air pressure at the earth's surface).
随着海拔的增加(高于海平面)，大气压力减小，导致吸入柴油机气缸内的空气量减少。
With the increase of altitude (above sea level), atmospheric pressure decreases, which leads to a reduction of the air amount inhaled into the cylinder of diesel engines.
冷暖空气并列排着，大气压力随高度的减少冷空气要比热空气来得快，因为冷空气压缩得更多。
Where warm and cool air lie side by side, atmospheric pressure decreases with height more rapidly in the cool than in the warm air, because the cool air is more compressed.
这股推动着我们的空气的质量被称为大气压力，或空气压力。
The weight of the air pushing on us is known as atmospheric pressure, or air pressure.
承受的压力比大气压力大的空气。
大气指的是包围着地球的全部空气，大气压力是靠近地球表面的全部空气的重量。
The atmosphere is all the air surrounding the earth. Atmospheric pressure is the weight of all that air against the surface of the earth.
有些矿井利用大气压力差引起空气自然流动，有些矿井则必须用扇风机把空气压人井内。
In some cases the difference in atmospheric pressure causes the air to circulate naturally; in others a fan must be used to pump air into the mine.
当供应压力等于大气压力时，空气进口必需处于全开位置。
Air inlet must be fully open when supply pressure is atmospheric.
当供应压力等于大气压力时，空气进口必需处于全开位置。
Air inlet must be fully open when supply pressure is atmospheric.
