absolute altitude

ABSOLUTE ALTITUDE , The actual distance the aircraft is above the ground.

绝对高度, 飞机离地面的实际距离.

Soil distribution from the foot to the top were: mountain red soil, mountain yellow soil, mountain yellow-brown soil and mountain meadow soil. Above the 1100 m of absolute altitude of the intermountain basin is bog soil.

The research of protective physiology on oxygen equipment of aviation is summed up as altitude higher absolute pressure protection, altitude lower absolute pressure protection and protective physiology studies on the airborne molecular sieve oxygen generating system.

将我国航空供氧装备生理研究归结为：高空高总压供氧防护高空低总压供氧简化装备防护和机载分子筛制氧防护生理研究三大部分。
