本文给出了近地卫星平面内轨道维持的一种方法。
A method for low orbit being maintained in the satellite orbit plane is given in this gaper.
为了保证冻结轨道的冻结特性,平面内轨道控制需要对半长轴、偏心率和近地点幅角都控制。
In order to guarantee the characteristics of frozen orbit, in-plane orbit control needs to adjust the semi-major axis, eccentricity, argument of perigee simultaneously.
在每个轨道内,天体之间的碰撞产生了巨大的热量和能量。
Within each orbit, collisions between planetesimals generated immense heat and energy.
So what that means is that we're limited in any atom to having two electrons per orbital, right, because for any orbital we can either have a spin up electron, a spin down electron, or both.
这意味着在一个原子内,每个轨道上可以有两个电子,对吧,因为对任何轨道,我们可以有自旋向上或者自选向下或者两者都有。
