coupling efficiency

• 耦合效率

coupling efficiency的用法和样例：

例句

1. Without the misalignment, coupling efficiency increases with the decreasing of taper length.
   失配不存在时，耦合效率随著锥长的增加而减小。
2. 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.
   这种相位全像术可以预期将发射出来的光直线导出有机发光二极体元件因此可以改善外部发光耦合效率。
