Some concepts such as relative rest reference frame, relative uniform motion reference frame, and relative accelerated motion reference frame was confirmed.
确定了相对静止系、相对匀速运动系、相对加速运动系的概念。
The performance of each portion of the triangle will in turn determine the relative strain on the rest of the structure.
各个部分的表现将决定了结构其它部分的相对压力。
The performance of each portion of the triangle will in turn determine the relative strain on the rest of the structure. The simplest interaction of the structure is as follows.
各个部分的表现将决定了结构其它部分的相对压力。
But things which were at rest will move at a constant velocity, opposite of the velocity that you have relative to me.
这些静止的东西都在匀速运动,方向正好跟你相对我运动的速度方向相反
In particular, the things that I say are at rest, you will say are moving backwards at the velocity that you have relative to me.
特别是那些在我看来是静止的物体,在你看来却在后退,后退的速度等于我们之间的相对速度
and I asked you to give yourself a percentage rating relative to the rest of the class, then if everybody was accurate, or at least not systematically biased, the number should add up to 50%.
我要你相比于其他同学的表现,给自己一个百分数,如果大家都准确地评价自己,或者说大家都不偏心于自己,那么平均百分数应该是50%的。
