1.高原:凡海拔在500米以上,顶面平缓,起伏较小,比较辽阔的高地称高原。我国有四大高原计青藏高原、内蒙古高原、黄土高原和云贵高原。这四大高原海拔都在一千米以上,但具有医学意义的一般指海拔在3000米以上地区。2.海拨高度:以海平面为基线,向上所测某地的高度称海拔高度,也称绝对高度。3.大气压:由地球大气的重量而产生的压强。其压力大小与海拔高度和温度等条件有关。在海平面上0℃时这个压力为760毫米汞柱(101.308kPa),称为标准大气压。随海拔
1. Plateau: Where the altitude above 500 meters, the top surface is gentle, less undulating, more extensive plateau called plateau. China has four plateaus Qinghai-Tibet Plateau, Inner Mongolia Plateau, Loess Plateau and Yunnan-Guizhou Plateau. The altitude of these four plateaus is more than one kilometer, but the general medical meaning refers to the altitude above 3000 meters. 2. Altitude: The sea level as the baseline, up to a certain height measured altitude, also known as absolute height. 3. Atmospheric pressure: the pressure generated by the weight of the Earth’s atmosphere. The pressure is related to the altitude and temperature conditions. This pressure is 760 mmHg (101.308 kPa) at sea level at 0 ° C and is called the standard atmospheric pressure. With altitude
