If you were here, and you go back to infinity, you reach exactly that speed, so if you fall in from infinity that is exactly the speed at which you reach the neutron star.
然后回到无穷大，你达到那个速度，如果你从无穷远处，以这个速度落到，中子星上，很明显。
That means you can get the speed of the neutron star, you can get the radius of the orbit, and you can get the period, just like we discussed before.
中子星的速率,得到轨道的半径，得到周期的大小，如之前讨论过的那样，现在取一个光学的。
You always lose your m, and so you find that the speed at which it reaches the neutron star M R M neutron star times G divided by R neutron star.
你们发现，它到达中子星的速度,等于二次根号,乘以G，is，the，square，root，of，two,除以中子星的半径,你们应记住这等式。
