A barometric altimeter indicates height above sea level or some other selected elevation . 气压高度表用以指示海平面或另外某个被选定高度以上的高度。
For altitudes in excess of 350, 000 feet the air density is less than 10 -7 of that at sealevel . 在高度高于350000英尺时，空气密度仅为海平面高度的107。
Eustatic cycle is the interval of time during which a eustatic rise and fall of sea level takes place . 全球性海面升降周期是发生一次海平面升和降的时间间隔。
For cartographical purposes heights are necessarily recorded above the geoid (sea-level) . 就制图的目的来说，所以需记录的高程是高出大地水准面（海平面）的高程。
for the overpressure, here p is the overpressure at altitude and is that at sea-level. 关于超压力，此处P是指在高处的超压力；是海平面上的超压力。
Coconut palms grew in spots on the circle of sand, and there were many gaps where the sand was too close to sea level for coconut . 在环形的沙滩上，零零星星地长着一些椰子树。不少地方地势太低，接近海平面，不适合椰树生长，形成一处处空地。
The beginning and the end of each significant depositional pattern is directly related to changes in position of sea level with respect to river deltas . 每一种有意义的沉积形式的开始和结尾，都与对应于河流三角洲的海平面位置的变化有直接的关系。
Elevation of station : 55m above mean sea level 气象站的高度：高于平均海平面55米
Elevation of station : 15m above mean sea level 气象站的高度：高于平均海平面15米
