在一次实验中的某个精确时刻，谐振器可能同时处于其放大和收缩状态；一次单一测量迫使其“选择”处于何种状态。

At a precise moment during one trial, the resonator might be both in its expanded and its contracted state; a single measurement forces it to "choose" which state to be in.

因此，高斯束谐振系统对高频遗迹引力波的频率和传播方向具有良好的选择效应。

Therefore, GBRS have a useful selective effect with respect to the frequency and propagation direction of relic HFGWs.

分析工频铁磁谐振时，选择正确的非线性电感励磁特性类型至关重要。

It is vital to choose the right excitation characteristic of the nonlinear inductor when analyzing ferroresonance.
