modulus of gain

• 增益系数

modulus of gain的用法和样例：

例句

1. The demand of high-power Raman pump light in FRAs is due to the low gain coefficient of the existing optical fibers.
   光纤拉曼放大器对于高功率拉曼激发光源的需求原因，来自于现行广为铺设的光纤之中，拉曼增益系数相对为低的理由。
2. When the interaction length or gain coefficient is changed, the SBS threshold is changed, and the intensity value of optical limiting is altered.
   当改变相互作用长度或者介质增益系数，即可以改变受激布里渊散射的产生阈值，进而改变输出脉冲空间限幅的幅值。
