Selecting the appropriate excitation frequency can well inhibit the conversion modeamplitude.
适当地选取激发频率，能很好地抑制转换模态幅值。

The bifurcation behavior of the coupled nonlinear normal mode is associated with detuning parameter and modeamplitude, but not with the nonlinear stiffness of uncoupling spring.
耦合非线性模态的分叉既与调谐参数有关又与模态振幅有关，但与非耦合弹簧的非线性刚度无关。

In digital scope, if the spike is high: In sample acquisition mode, it will be shown as random amplitude spikes.
