本文运用一种简化理论——小角度近似法试图解释回转仪在转动中的一种奇怪行径:章动.本文突出物理实质,简化了较复杂的数学运算,给读者以明晰的概念.
In this paper, we use a simplified theory - a small angle approximation to try to explain the strange behavior of the gyroscope in rotation: nibbling. This article emphasizes the physical essence, simplifies the more complicated mathematical operations and gives readers a clear concept.
