同时本文在二群失稳模式的假设下，得出了机组电磁功率与转子相对惯性中心角的变化曲线为一正弦曲线。

Meanwhile, under two-group instability modes, it is discovered that the curves between electric power of generator unit and rotator's angle in relative to center of inertia is a sine curve.

反思的动机方面似乎有许多问题尚未被探索——例如，与教师可能进行的习惯性反思相对的，受外部激励的反思的价值。

There appear to be many unexplored matters about the motivation to reflect—for example, the value of externally motivated reflection as opposed to that of teachers who might reflect by habit.

有了这些适当的简化，我们现在就可以把你的男朋友看作是一个惯性系，由之我们能够计算这些相对性事件的结果。

With these simplifications in place, we can now treat your boyfriend as an inertial system, from which we can calculate the consequences of relativistic events.

If I am an inertial observer, another person moving relative to me at constant velocity will also be an inertial observer.

如果我是惯性观察者,那另一个相对于我做匀速运动的人,也是一个惯性观察者

There's infinite number of them, but they're all moving relative to each other at constant velocity.

有无数个惯性观察者,但是他们都在相对于彼此,做匀速运动

So the Earth is an inertial frame of reference, if you go in a train relative to the Earth at constant velocity, you're also inertial.

所以,地球是一个惯性参考系,如果你坐在相对于地球匀速运动的火车里,你也处于惯性状态
