本文研究了一种利用大气压力与海平面高度的关系，使用单片机实现气压高度测量的系统。
An air pressure altitude measurement system which took advantage of the relationship between air pressure and altitude above sea-level was studied and realized by MCU.
或者，如果天气晴朗，你可以测量气压计的高度，然后把它立于地面，再测量它的影子的长度。
Or if the sun is shining you could measure the height of the barometer, then set it on end and measure the length of its shadow.
测量气压是以汞柱高度为计算单位。
The atmospheric pressure is measured and calculated by the height of the mercury .
但是该装置利用气压计来测量高度。
气压式高度表测量气压是参照海平面的，透过一连串的真空膜盒、齿轮和弹簧来移动刻度盘上的指针。
The mechanical pressure altimeter measures atmospheric pressure relative to sea level through a series of bellows, gears, and springs, which move Pointers on a dial.
