| 摘 要： | 提出把LC振荡器等效成负阻振荡器的新观点，并以电容三点式振荡器为例，利用物理概念导出了该振荡器的振荡条件和振荡频率的准确公式，并将结果与相关讨论进行比较。由此推断：所有LC振荡器均可等效为负阻振荡器，从而可方便得到振荡条件和振荡频率。该方法的特点是物理概念清晰，数学过程简便。

| Abstract: | This paper put forward a new view that LC oscillator is equal to negative resistance Oscillator in effect .In addition ,the paper concluded accurate formulas of OSC condition and OSC frequency about LC oscillator by using physics notions and taking Three-point Capacitance Oscillator as an example .Comparing this result with relative discussion , the paper reached the conclusion that that all the LC oscillator are equal to Negative Resistance Oscillator in effect is the basis of getting OSC condition and OSC frequency .The characteristic of this method is that physics notionsare very clear and teaching process is very simple . |
