"euxenite:a lustrous, blackish-brown rare-earth mineral consisting primarily of cerium , erbium, titanium, uranium, and yttrium."

"稀金矿:一种光亮色稀土矿石,主要由铈、铒、钛、铀和钇构成."

Erbium-doped superfluorescent fiber sources (SFS) pumped near 980nm in double-pass backward (DPB) configuration have been characterized through theoretical simulation.

理研究了双程后向结构掺铒光纤超荧光光性。

Erbium ions concentration is obtained by the information of measured coefficients along with modeling of double-pass backward (DPB) superfluorescent fiber source (SFS).

再利用这些系数和复行后向超萤光光纤光模拟，得到掺铒光纤浓度。
