1·One problem with the collision hypothesis is the question of how a satellite formed in this way could have settled into the nearly circular orbit that the Moon has today.
碰撞假说的一个问题是，以这种方式形成的卫星是如何在月球现在的近乎圆形的轨道上运行的。
2·You've got negative charge in motion, and it's in a circular orbit.
负电荷在运动，它们处在一个环形的轨道中。
3·Thee earth moves in an approximately circular orbit around the sun.
地球在一个近似正圆的轨道上绕着太阳运行。
4·That also means that the period t must be larger than the period in your circular orbit.
这也意味着，周期T比圆形，轨道的周期大。
5·As an example, say you have an item that you want to move in a circular orbit around the screen.
例如，假设想要有一个在屏幕中沿着圆形轨迹运动的项。
6·There might be a distant object in a more stable, more circular orbit that has gone unnoticed so far.
也许有这么一个遥远的天体具有一个更加稳定的更加圆润的轨道而至今未被我们发现。
7·And therefore, the total energy now is larger than the total energy that I had in my circular orbit.
因此，现在的，总能量比，在圆形轨道中要大。
8·Chaotic attitude motion of a magnetic rigid spacecraft in a circular orbit of the earth is treated.
研究在地球万有引力场和磁场中的磁性刚体航天器在圆轨道上的混沌姿态运动。
9·However, this algorithm does not apply for circular orbit cone-beam scan with line-focus X-ray source.
但是，这种算法不能满足线X射线源圆轨道锥束扫描的情况。
10·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。
