摘　　要：对SrTiO3晶体环在不同几何尺寸蓝宝石谐振腔下的温漂补偿效果及其对蓝宝石谐振腔无载Q值的影响进行了仿真和数值计算，总结出不同尺寸蓝宝石谐振腔温度系数和无载Q值的变化规律。讨论了零腔频漂移补偿点的存在范围。最后通过对填充因子η’随几何尺寸变化的计算和对温度补偿效果的讨论，得到了兼顾体积、Q值、填充因子η’、s参数、温度漂移系数的填充SrTiO3补偿晶体蓝宝石谐振腔。Temperature-compensated effect of SrTiO3 ring is calculated for sapphire cavities with different dimensions. The rules for temperature coefficient and unloaded Q changed with different dimensions is studied. Also the region, in which microwave cavity dimensions with zero cavity frequency shit（ temperature coefficient） can be found, is studied. At last for consideration of volume, unloaded Q, temperature coefficient, filling factor η＇ and S parameter, a low - temperature coefficient sapphire loaded cavity for active H maser is designed.
