They are the radius of the orbit, the energy of the system and the velocity of the electron, and I am just going to present you the solutions.
它们是轨道的半径，系统的能量以及电子的速度，我接下来给你们展示解法。
And out of this information you get the radius, the velocity and the period, assuming that you are on Earth in the plane of the orbit of the stars.

So, in principle, you can determine for each one of those stars the velocity in orbit, the radius of their orbit and, of course, the period of the binary system.
所以从原则上来说，你们可以决定任何,恒星在轨道中的速度，轨道的半径以及，当然，二元体系的周期。
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.

The radius of the Earth's orbit is about 400 times the radius of the Moon's orbit.
地球的轨道半径大约是月球轨道半径的400倍。
- not the radius of the donor — you know the radius of the orbit, and you know the period.
而是轨道的半径-，你知道了周期，现在情况是。
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。
R This is the radius of the orbit in which the electron travels.
是距离，So，，this，distance，here，is，R。,这是轨道的半径,就是电子运动的地方。
Let's look first of all at the radius of the orbit.
首先是轨道半径。
The sun will then become what's called a red giant, and its radius will reach just past the orbit of Venus.
太阳就变成了所谓哦红巨星，它的半径将会达到以前金星的运行轨道。
This is the kinetic energy for something in orbit at this radius, and this is the potential energy.
这是在轨道内这个，半径的物体的动能，这是势能。
Out of that pops its velocity in orbit and out of it pops its radius.
然后是轨道上的速度,然后是半径。
So this is our circular orbit X with radius r, and at location X, at 12:00, that is where I fire my rocket.
这是我们的圆形轨道,半径为r，在点，12点的位置,是我发射火箭的位置。
One astronomical unit is equal to the average radius of the Earth's orBit, aBout 93, 000, 000 miles.
一个天文单位等于地球轨道的平均半径，大约是93，000，000英里。
The acceleration may in turn be obtained from the velocity of the satellite and the radius of the orbit.
这个加速度又可根据卫星的速度和它的轨道半径来求得。
