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.

- 從實(shí)驗結果可以看出,鋱玻璃樣品的費爾德常數在333K時(shí)比293K時(shí)減小了近20%25,則當其作為法拉第偏頻介質(zhì)時(shí),必須進(jìn)行溫度補償。
