It is found in the experiment result that the Verdet constant of the terbium glass sample in 333K is about 20% less than which in 293K. So temperature compensation must be taken when the terbium glass is used as Faraday bias element medium.

- 从实验结果可以看出,铽玻璃样品的费尔德常数在333K时比293K时减小了近20%25,则当其作为法拉第偏频介质时,必须进行温度补偿。
