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.

为了改善滤波器的性能，提高滤波器的选择性，提出了互补开环谐振器（COLR）。

To improve the performance and selectivity of filter, a complementary open-loop resonator(COLR) is proposed.
