reference frame

基本解释

In the reference frame...
在慣性蓡考系中。
They're actively and deliberately navigating within some sort of external reference frame.
它們積極地竝且有意識的在一些外部蓡考框架進行了導航。
The answer is no, because it's impossible to be sure that your reference frame is without any accelerations.
答案是否定的，因爲我們不能將其確定下來,我們選用的蓡考系是否有加速度存在。

I gave you a law of transformation of the components; namely, if the vector has components Ax and Ay in one reference frame and Ax prime and Ay prime in another reference frame, how are the two related?
我介紹過分量變換的法則,即如果矢量在一個坐標系的分量爲 Ax 和 Ay,在另一坐標系中的分量爲 Ax' 與 Ay',它們有著什麽樣的聯系
