propagating mode meaning in Chinese

传播模
传播膜

we have to distinguish between the propagating modes with real valued β, and the evanescent modes with imaginary β.
我们必须分别考虑具有实数的导模和具有虚数的消失模。

The long period fiber gratings ( lpfg ) have been chosen to be the filters finally after comparing several filters . the specific loss could be achieved by the coupling between two co - propagating modes in lpfg
Lpfg利用光纤内同向传输模式之间的耦合,把正向传输的基模能量有选择性的耦合到其它正向传输的模式中,实现选择性损耗。
The term of mode - filtered light refers to the observation that light initially propagating down an optical fiber can be decoupled from that fiber by increasing the cladding ri at the core / clad interface with a permeating analyte , thus changing the allowable propagating modes within the fiber , resulting in a continuous and nearly linear increase in mode - filtered light with increasing cladding ri
所谓模式滤光，是指分析对象进入光纤包层引起光纤芯包界面的折射率增加，导致光纤内的部分传导模不满足传导条件而从光纤的包层中侧漏出来的光学信号，它与包层折射率的增量在一定条件下线性相关。
