【摘要】：從正弦激勵下線性二階系統(tǒng)的微分方程出發(fā),結(jié)合阻尼振子的受迫振動以及RLC串聯(lián)、并聯(lián)諧振電路等具體物理情境,剖析了品質(zhì)因數(shù)Q在頻率特性、能量轉(zhuǎn)換以及系統(tǒng)各物理參數(shù)等多個層次上的內(nèi)涵,進(jìn)而探討如何更好地為工科各專業(yè)學(xué)生講授品質(zhì)因數(shù)這一概念.
[Abstract]:Based on the differential equation of the linear second order system under sinusoidal excitation, combined with the forced vibration of the damped oscillator and the physical conditions such as RLC series and parallel resonant circuit, the characteristics of the quality factor Q in frequency are analyzed. This paper discusses how to better teach the concept of quality factor to the students of engineering major in terms of energy conversion and the connotation of various physical parameters of the system.
