高空的主要特點就是氣壓低、溫度低。當達到某种高度時,稀薄的空氣及寒冷的環境就不足維持人類的生存;今日飛機的活動範圍雖然仍在變溫層內,但最高限度已達到15,000公尺,由於航空事業發展迅速,短期內必將超過此種限度,人类在高空中的活动範圍擴大了,高空環境也給人類带來了更嚴格,更複雜的生活條件,為生存而待解決的問题也就更多了。
The main features of high altitude is low pressure, low temperature. When a certain altitude is reached, lean air and cold environments are not enough to sustain humankind. Although the range of aircraft today is still within the variable temperature zone, the ceiling has reached 15,000 meters. Due to the rapid development of the aviation industry, short-term It is bound to exceed this limit. The scope of human activities in the sky has been widened. The upper-air environment has also brought more stringent and complicated living conditions to mankind. And there are also more problems to be solved for survival.
