simple pendulum

基本解釋

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(yùn)動(dòng)雖然簡(jiǎn)單卻不實(shí)際，實(shí)際情況需要在理想情況的基礎(chǔ)上進(jìn)行修正和改進(jìn)。
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(yīng)用非線(xiàn)性譜分析法對(duì)大位移單擺在隨機(jī)激勵(lì)作用下的非線(xiàn)性隨機(jī)振動(dòng)問(wèn)題進(jìn)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(xiàn)一些模糊認(rèn)識(shí)，即認(rèn)為單擺在振動(dòng)中所受的回復(fù)力就是擺球所受重力與繩子拉力的合力，顯然，這是錯(cuò)誤的。
