coupling efficiencies的用法和樣例：
例句
- Without the misalignment, coupling efficiency increases with the decreasing of taper length.
失配不存在時(shí)，耦合效率隨著(zhù)錐長(cháng)的增加而減小。 - The phase holograms are expected to be able to guide the emission straight out from the OLED device and hence the external light coupling efficiency can be improved.
這種相位全像術(shù)可以預期將發(fā)射出來(lái)的光直線(xiàn)導出有機發(fā)光二極體元件因此可以改善外部發(fā)光耦合效率。
