发布时间：2018-07-16 11:33
【摘要】：从正弦激励下线性二阶系统的微分方程出发,结合阻尼振子的受迫振动以及RLC串联、并联谐振电路等具体物理情境,剖析了品质因数Q在频率特性、能量转换以及系统各物理参数等多个层次上的内涵,进而探讨如何更好地为工科各专业学生讲授品质因数这一概念.
[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.
