中文摘要：

利用具有温度控制的磁光调制倍频法,测量了Tb20顺磁性铽玻璃在293K～343K范围内不同温度下的本征旋转和费尔德常量的温度响应特性.结果表明,这种铽玻璃具有敏感的温度响应.以此种玻璃制作各种磁光器件,特别是在准确度要求很高的零锁区激光陀螺中作为法拉第偏频器件时,必须进行温度补偿.最后给出了两种可能的温度补偿方法.

英文摘要：

A magneto-optical-modulating-double-frequency system is set up and actualized with temperature controlled added. The eigen rotation and Verdet constant of the paramagnetic terbium glass Tb20 are measured in 293K-343K. With the temperature goes higher,the eigen rotation increases to a stable value gradually and the Verdet constant decreases keeping to the theoretical formula. The experimental results show that the terbium glass has sensitive temperature response. When it is used, especially used as Zero Lock gyro Faraday bias element, temperature compensation must be taken, and several potential approaches to temperature compensation are also given.
