modulus of gain的用法和樣例：
例句
- The demand of high-power Raman pump light in FRAs is due to the low gain coefficient of the existing optical fibers.
光纖拉曼放大器對于高功率拉曼激發(fā)光源的需求原因，來(lái)自于現行廣為鋪設的光纖之中，拉曼增益系數相對為低的理由。 - When the interaction length or gain coefficient is changed, the SBS threshold is changed, and the intensity value of optical limiting is altered.
當改變相互作用長(cháng)度或者介質(zhì)增益系數，即可以改變受激布里淵散射的產(chǎn)生閾值，進(jìn)而改變輸出脈沖空間限幅的幅值。
