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.

最后，在光微域的转角处，你可以看见环形谐振路，是用传统的方式（非光晶体方式）来表示用于等的谐振腔。

Abstract: A network model was developed to analyze a piezoelectric source driving a resonantor to investigate the coupling of the piezoelectric loudspeaker with a thermoacoustic resonantor.

为了研究压驱动与热声谐振腔间的耦合特性，建立了压驱动系统的网络模拟模型。
