根据现行的政府轨道碎片缓减标准做法,航天器发射实体需要做什么?
What is a space vehicle launching entity required to do according to the current Government Orbital Debris Mitigation Standard Practices?
把你的个人卫星发射到轨道上,可能听起来像是科幻小说里的情节。
Having your personal satellite launched into orbit might sound like an idea straight out of science fiction.
它们可以到达更远的轨道;美国国家航空航天局计划在其未来的大部分发射任务(尤其是去月球和火星的)中携带立方体卫星。
They can attain more distant orbits; NASA plans for most of its future earth escaping payloads (to the moon and Mars especially) to carry CubeSats.
So we can actually pop an electron or eject an electron from any single orbital that is occupied within the atom.
任何一个被占据轨道,打出一个电子,或者说发射出一个电子。
It makes sense that it's going to come out of the highest occupied atomic orbital, because that's going to be the lowest amount of energy that's required to actually eject an electron.
从最高占据轨道上,去掉一个电子是合理的,因为这样是发射一个电子,所损失的最低能量。
So, for example, it's not just the 2 p that we could actually take an electron from, we could also think about ejecting an electron from the 2 s orbital.
比如,我们不只可以从,2,p,轨道上,打出一个电子,还能考虑从,2,s,轨道上,发射出一个电子。
