inertial frame

基本解釋

The passengers are deluded into believing themselves to be in an inertial frame with no forces acting.
乘客誤以為自己處于慣性系中，且不受外力作用。
And therefore, in spite of these accelerations we will accept this hall as a reasonably good inertial frame of reference in which the First Law then should hold.
所以，幾乎可以忽略不計(jì),教室是一個(gè),很好的慣性參考系,第一定律在這兒是成立的。
In relative kinematical model research aspects, based on the two body model of the satellite in earth-centered inertial frame, the precision relative kinematical model of satellite is presented.
在相對(duì)運(yùn)動(dòng)模型研究方面，基于衛(wèi)星在地心慣性系下二體模型，推導(dǎo)了衛(wèi)星精確相對(duì)運(yùn)動(dòng)模型。

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(gè)慣性參考系,如果你坐在相對(duì)于地球勻速運(yùn)動(dòng)的火車(chē)?yán)?你也處于慣性狀態(tài)
