resonator

The usage of Helmholtz resonator is restrained by the space, which is only available for rectangular resonator somewhile.

实际应用中，共腔的使用往往受到安装空间的限制，有时候只能安装矩形腔。

Finally, in the micropolis corners you can see ring resonators, which are a conventional (non photonic-crystal) way to achieve a resonant cavity for use in channel-drop filters, etcetera.

，光子微域的转角处，你可以看见环形谐电路，这是用传统的方式（非光子晶体方式）来表示用于滤波器等的谐腔。

The external inspirator is available to drive the resonator to produce traveling wave.Under resonant frequency the distortion of resonator reached a peak.

外激励的驱动方式可以使扁环型谐管产生有效的行波分量，谐频率下，谐管腔的综合变形量大。
