resonating body meaning in Chinese

共鸣箱

The development of filters , resonators and other telecommunication technology required better dielectric materials . the dielectric materials , used as the resonate body , should be high in dielectric constant , low in dielectric loss and a near zero temperature coefficient of dielectric constant in high frequency band , also could be sintered in a relative low temperature so as to reduce production cost , and what ’ s more , the miniaturization and reliability of materials are also the main aspects in the research work of high frequency band dielectric materials
随着滤波器、谐振器等器件以及通信技术的发展,人们对电介质材料的要求越来越高,要求作为介质谐振腔的电介质材料在高频段下具有高介电常数,低介电损耗,接近于零的介电常数温度系数,还要求高频电介质材料能够在较低的烧结温度下烧成,以降低实际生产的成本,此外,材料的小型化,高可靠性也是高技术高频介质材料的重要研究方向。
