共振现象的相图及动力学特征

The Phase Graph and Dynamical Characteristic of the Resonance Phenomenon

共振是一种物理现象,当强迫力的频率等于物理系统的无阻尼自然(固有)频率时,系统会产生共振.该文研究了受迫振荡的耗散系统的相图变化,解释了动力学特征———共振.

Resonance ,as a kind of physics phenomenon,often takes place when the angular frequency of the driving force is equal to the 'intrinsic' angular frequency of the dissipative system′s forced vibration. By Changing relative parameters, we get some phase graph the dissipative system′s forced vibration and explain the dynamical characteristic-Resonance.
