In reality , many human constructs can be seen from earth orbit 而实际上,在近地轨道上很多人工建筑物都可以被看到。
Low earth orbit 近地轨道
S [ ace debris are the general domination of all man - made objects including fragments and elements thereof , in earth orbit or re - entering the atmosphere , that are non - functional 摘要空间碎片是散布在近地轨道和同步轨道上的非功能性人造物体包括其碎片和零件的总称。
In this paper , author mainly completed works as followed . first , summarized oversea collision early warning theories and orbit maneuver methods and analysed the low earth debris environment 作者在论文中主要完成了以下内容: 1 )综述了国外碰撞预警理论和规避方法,分析了近地轨道碎片环境。
Surface materials of the space inflatable structures would be influenced by vacuum thermo - cycling and vacuum ultraviolet ( vuv ) when the spacecrafts operated in low earth orbit 在低地球轨道飞行的航天器,真空热循环与真空紫外辐照等近地轨道空间环境成为影响空间充气展开结构材料的重要因素。
