spontaneous emission noise meaning in Chinese

自发发射噪声
自发射噪声

The justification of(13. 2-2)as a representation of spontaneous emission noise is provided by the discussion preceding(13. 1-7) .
根据上面对式（131-7）的讨论，就可以将公式（132-2）看作是自发辐射噪声的表达式。
4 . the lpfgs are used in single wavelength er - doped fiber amplifiers ( edfas ) as a spontaneous emission noise ( ase ) filter , and the gain of the edfa is increased by 7db and the noise figure ( nf ) is decreased by 0 . 5db , for the first time
4 、成功研制了掺铒光纤放大器,首次将高频co2激光脉冲写入的长周期光纤光栅应用到掺铒光纤放大器中作为自发辐射噪声滤波器,使edfa的增益提高了7db 、噪声系数降低了0 . 5db 。
Because power management in this thesis aims at amplified spontaneous emission noise of erbium ? oped fiber amplifier ( edfa ) , the thesis introduces the simplified stark ? split energy levels of er3 " , amplified working mechanisms of er3 * and working performance of edfa in details
因为本文所采用的功率管理主要是针对edfa掺饵光纤放大器所产生的自发辐射噪声去采取均衡措施，所以论文中详细介绍了edfa中铒离子的stark分裂的简化的能级模型、铒离子的放大工作机理及edfa的工作特性。
