The unique radio astronomical technique of space very long baseline interferometry ( svlbi ) is an extension of the ground - based vlbi into the space 空间甚长基线干涉测量技术svlbi ( spaceverylongbaselineinterferometry )是地面vlbi测量在空间的延伸。
Without the target ' s maneuver to make itself easier to kill , a ground - based shot would likely have to be made from the side ? or “ out of plane , ” in space navigation parlance 如果目标不作如此机动,而让它容易被击中的话,地面攻击将很可能从侧面飞来。
To take action against space junk , nasa engineers in 1996 explored the idea of using a ground - based laser to deflect it out of a spacecraft ' s path 为了预防太空废弃物造成损害, nasa的工程师在1996年想出了一个点子,利用地面雷射使太空废弃物转向,以避开太空船。
Then both kapton film and protective coating were exposured on the ground - based simulation facilities for ao to study the erosion behavior of kapton and protective film 然后在原子氧( atomicoxygen , ao )侵蚀地面模拟设备中对kapton薄膜以及防护膜进行原子氧侵蚀试验。
" over the horizon " technologies - these facilitate ground - based methods of harassment ( eg the alaskan haarp project which bounces signals off the ionosphere ) “视距外”技术-这些促进了以地面为基础的折磨方法(例如阿拉斯加高频活跃极光研究计划,它反射信号到电离层) 。
