reference frame

基本解釋

In the reference frame...
在慣性參考系中。
They're actively and deliberately navigating within some sort of external reference frame.
它們積極地并且有意識的在一些外部參考框架進行了導航。
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，因為我們不能將其確定下來,我們選用的參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為 Ax 和 Ay,在另一坐標系中的分量為 Ax' 與 Ay',它們有著什么樣的聯(lián)系

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,地球是一個慣性參考系,如果你坐在相對于地球勻速運動的火車里,你也處于慣性狀態(tài)

Then we've just shown here, it's an accelerated frame of reference.
就像這里寫的一樣,它是個有加速度的參考系
