奇异振荡现象与多模振荡现象以及一类新型振荡器的研究

         

摘要

基于对电路起振问题的规范化分析,系统地阐释了相量分析的有效性与局限性,并且提出了用于判断(e)φr(ω)/(e)ω|ω=ω1符号的象限法.设计了六个电路,分别对它们解析并验证了多种振荡现象的存在与获得方式.首次提出了电路的奇异振荡现象,并证实了它作为一大类振荡现象的普遍性.首次提出并验证了单个电路中多模振荡现象的存在.另外,多个非常规的振荡器实例作为一类新型振荡器的存在,更是集中体现了对于传统振荡器理论基本要求的突破.据此,基本上可以建立起关于振荡现象和振荡器的新的、比较完整的阐释系统.%Grounded on the normalized method on the en-oscillation analysis for circuit,the availability and the limitations of the phasor method analysis is elucidated systematically,and moreover,the quadrantal technique for the judgement of the sign of (e)φr(ω)/(e)ω|ω=ω1is advanced.Six circuits are designed which aim to analyze and verify the oscillations of many kinds.It is the first time for the odd oscillation could be depicted,which could be experimentally proved as a main variety of oscillation.The multi-mode oscillation is also put forward theoretically as well as practically for the first time.Being examples of a new sort of oscillator,several unconventional oscillators can mark the breakthrough of the basic demand in traditional theory.Thus,a new-built,systematic comprehension about oscillation and oscillator is mainly demonstrated.
