人民教育出版社 1997年出版的高中《物理》第三册 (选修本 )第 96面关于通信卫星轨道的叙述中有这样一段话 :“通信卫星的轨道一般都采用‘地球静止轨道’,也称‘地球同步轨道’.即卫星转动的周期与地球自转的周期相同 ,相对于地球静止 .”这段话容易让人理解为 :地球同步轨道? In the narration of the 96th aspect of the third book (edition) of high school “Physics” published by the People’s Education Press in 1997, there is a paragraph in the narrative of the communication satellite orbit: “The orbits of communication satellites generally use the “geostationary orbit”, also known as ’Earth geosynchronous orbit’. That is, the cycle of a satellite’s rotation is the same as that of the earth’s rotation, and it is relative to the earth’s motion." This passage can be easily understood as: geosynchronous orbit?
