部分填充介质的谐振腔用于量子频标、微波振荡器,微波滤波器中。使用小损耗的介质能制出品质因数高及尺寸远小于空腔谐振器的微波谐振腔。本文列举了内部体积分成为半径 R_1>R_2>R_3的三个同心区域的圆柱谐振腔的计算结果(图1)。R_2与 R_3之间的 The partially filled resonator is used in quantum frequency scales, microwave oscillators and microwave filters. The use of small loss of medium can produce a high quality factor and size is much smaller than the cavity resonator microwave resonator. In this paper, the calculation results of cylindrical cavity with internal volume divided into three concentric regions with radius R_1> R_2> R_3 are listed (Fig. 1). Between R_2 and R_3
