stable oscillation

In this paper, the stability condition of optical resonator is introduced, the power losses of stable resonator and the threshold condition of optical oscillation is discussed, and the formulation of the relationship between the gain coefficient of work substance and the losses factor is derived.

本文对光学谐振腔的稳定条件做了介绍，并讨论稳定谐振腔的功率损耗和光振荡的阈值条件，导出了工作物质的增益系数与损耗因子的关系式。

For stable operation of the magnetron, the preoscillation voltage should be lower than ehe threshold voltage, while the mode of this space charge oscillation should be the same as the π mode oscillation on the resonating cavities.

为了使磁控管能稳定工作，就要使预振电压低于门槛电压，并且使空间电荷振荡的模式与谐振腔上高频振荡的π模同步。

Through the principle of the equivalent model of the analysis combined with the basic principle of the voltage controlled oscillation FBAR using capacitive feedback oscillation, its oscillation frequency to a stable output.

通过对压控振荡的基本原理的分析结合FBAR的等效模型采用电容式反馈的原理起振，使其振荡频率能稳定的输出。
