我们考虑一个非线性谐振器与一个衰减时间相对较短的线性谐振器非线性耦合的动力学。在这种情况下，次级（线性）谐振器绝热地跟踪主（非线性）谐振器。该模型是由正在进行的纳米谐振器实验工作激发的，通过解析和数值分析表明，主谐振器的线性和非线性特性可以通过与次级谐振器的耦合而显著改变。这样的安排可以在应用中提供调谐谐振器特性的实用手段。
We conside the dynamics of a nonlinear resonator that is nonlinearly coupled to a linear resonator that has a relatively short decay time. In this case, the secondary (linear) resonator adiabatically tracks the primary (nonlinear) resonator. This model, which is motivated by ongoing experimental work in nano-resonators, is analyzed analytically and numerically to show that the linear and nonlinear characteristics of the primary resonator can be altered in a significant manner by the coupling to the secondary resonator. Such an arrangement may provide a practical means of tuning resonator characteristics in applications.
