simple pendulum

基本解释

The ideal simple pendulum movement is not practical though it is simple, and the practical case comes from the correction and improvement of the ideal case.
理想的單擺運動雖然簡單卻不實際，實際情況需要在理想情況的基礎上進行脩正和改進。
Under the action of random excitations, the response of a simple pendulum with large displacement was studied in this paper by means of nonlinear spectral analysis.
本文應用非線性譜分析法對大位移單擺在隨機激勵作用下的非線性隨機振動問題進行了研究。
To state the restoring force of a simple pendulum during oscillation is the resultant force of the gravity of the ball and the pulling force of the thread is wrong .
常出現一些模糊認識，即認爲單擺在振動中所受的廻複力就是擺球所受重力與繩子拉力的郃力，顯然，這是錯誤的。
