The tendency of a body in motion to continue in motion along a straight line is known as inertia. 運動(dòng)物體繼續作直線(xiàn)運動(dòng)的傾向叫慣性。
A mechanical movement includes a frame adapted to move only along a linear path of travel. 機械運動(dòng)包括一個(gè)適合于只沿著(zhù)直線(xiàn)運動(dòng)的框架。
The practical use of synchronous spindles however shows that the dynamics of the spindle and linear drives produce mistakes in the synchronisation. 但實(shí)際使用同步主軸，同步化過(guò)程顯示，軸的動(dòng)態(tài)運動(dòng)和線(xiàn)性運動(dòng)產(chǎn)生錯誤。
