高温超导谐振器技术及其应用研究综述

目前，用超导临界温度比较高、微波表面电阻Rs较小、超导性能稳定的高温超导薄膜制成的高温超导谐振器已在工程上得到广泛应用。高温超导谐振器较其他谐振器具有Q值高、噪声小、损耗低等优点。它不仅可作为高性能微波器件使用，还可用来开展超导薄膜或介质衬底材料的微波性能研究，在航天领域有望用于空间原子钟。文章对高温超导谐振器的原理、结构、各领域应用及国内外研究情况进行综述，并给出我国发展此项技术的建议。

The application of high-temperature superconductor microwave resonators

Since the discovery of high-temperature superconductors with superconducting transition temperature higher than the boiling point of liquid nitrogen,studies have been focused to obtain them,which usually feature high superconducting critical temperature,low Rs and stable performance.They see considerable applications in engineering areas.The high-temperature superconducting resonator is an example.Compared with the normal resonators,the high-temperature superconducting resonator has high Q,small size,light weight,low noise,and other good qualities.It not only can be used in microwave devices,but also can be used to study the microwave properties of superconducting film or dielectric substrate material.
