一些谐振系统象许多物理系统一样,受高电平激励时,也呈现非线性特性。这种非线性导致谐振频率随激励功率而变化(幅——频效应)并造成相位和振幅响应失真,随着这些效应由此而产生是两个或多个稳定状态、谐波以及分谐波及滞后现象,最终形成可能稳定状态——无秩态。本文对高Q的和低Q的谐振器两种情况,研究了分谐波的产生阳无秩态的形成,苜先提出了这些非线性系统模式,然后给出了石英晶体谐振器(高Q系统)和锁相环(低Q系统)两种实际系统的测量结果。
Some resonant systems, like many physical systems, also exhibit non-linear behavior when excited by high levels. This non-linearity causes the resonant frequency to vary with the excitation power (amplitude-frequency effect) and distorts the phase and amplitude response, with these effects resulting from two or more steady states, harmonics and sub-harmonics And lag phenomenon, the final formation of a possible steady state - no state. In this paper, the formation of subharmonic positive stateless state is studied for two cases of high-Q and low-Q resonators. Alfonso proposed these non-linear system modes first, and then gave the crystal resonator of high Q System) and phase-locked loop (low-Q system) two actual system measurements.
