轨道高度 meaning in Chinese
orbit altitude
orbital altitude
orbital height
Examples
- The attack is believe to have occurred as the weather satellite flew at 530 mi . altitude 4 deg . west of xichang located in sichuan province
据信该卫星是在530英里轨道高度，西昌以西4度的地点飞行。 - Typically objects at an orbital altitude of 200 kilometers decay in several days , those at 400 kilometers in several months , and those at 1 , 000 kilometers in about 2 , 000 years
一般来说，物体在轨道高度200公里时会在几天之内焚毁，在400公里处需要几个月，而在1000公里高处的物体约需2000年。 - However , there exist the so - called van allen radiation belts at this hight . the solar cells would work there for only several days , even for ‘ radiation hardness ’ si solar cells
但是,在这个轨道高度上存在所谓vanallen辐射带,在这里即使是“抗辐射”的si太阳电池也只能正常工作几天时间。 - The award will go to the team that first takes three people to a 100 - kilometer suborbital altitude , returns to earth , and repeats the feat within 14 days after replacing less than 10 percent of the dry weight of the vehicle
得奖的团体，首先必须载送三名人员进入100公里的次轨道高度，再返回地球，接著在14天之内重复上述动作，而载具的更新不能超过净重的10 % 。 - The advantages of using leo satellite are as following : on the one hand the satellite orbit is low , so the transmission delay is short , the power loss is small ; on the other hand the development of cell communication , multi - access , frequency multiplex and etc also provide a technique guarantee to the leo satellite - mobile - telecommunication . so the leo system is considered to be a satellite - mobile - communication system with a great future
低轨道卫星是一种运行于1000公里左右的高空中的人造卫星，利用leo卫星实现个人通信的优点在于：一方面卫星的轨道高度低，使得传输延时短、路径损耗小，多个卫星组成的星座可实现真正的全球覆盖，频率复用更有效：另一方面蜂窝通信、多址、点波束、频率复用等技术的发展也为低轨道卫星移动通信提供了技术保障。
