closed resonator meaning in English

闭合共振器
闭合谐振腔

Second , this thesis analyses the scenario of a closed resonator fiber gyro , as well as the theory
本文还讨论了一种闭环谐振式光纤陀螺的方案，并做了原理分析。
With frequencies arising , close resonators have limitations on lowing quality factor 、 reducing the size of resonator and modes denseness etc . within microwave frequencies , electromagnetism open resonator technologies are widely used in electrical dielectric parameter measurement of low loss dielectric material
随着频率的升高,封闭的谐振腔存在品质因数降低、腔体尺寸减小、模式密集等局限性,所以在毫米波频段,测量低损耗材料电介质参数最常采用的是电磁开腔技术。
