At infinity, there's no stored potential energy, and it drops off more and more negative as one over r.
在无限远处,没有储存的势能,并且它向负方向减少,当距离超过R时。
We are mainly engaged in the r&d, manufacturing, marketing and service of new coatings which are green, environmental protection, low carbon energy saving.
主要从事绿色、环保、低碳节能等新型涂料的研发、制造、营销、服务。
It is not as much a coincidence as you think, of course. But if something is in orbit, this is the orbital speed at radius r, then always is its total energy is half the potential energy.
但并不是巧合,当然,但如果某物在轨道里,这是在半径r的速度,则总是它的总能量,是势能的一半。

OK, so R minimum, the minimum separation occurs when the energy is at its minimum.
好的,所以R处是最小值,间距最小值出现在,当能量为最小的时候。
