查询词典 longitudinal wave

Reaearch on mode selection theory of coupled resonator and single, double wave plate longitudinal-mode splitting theory.

研究耦合腔激光器的选模原理以及单、双波片纵模分裂原理。

In these lasers, a section of Erbium doped fiber without undergoing bump used as saturatable absorber. A self-written grating may be formed by stable standing wave in this absorber. Because selfwritten grating possesses a characteristic of very narrow rejection band and can suppress any other side-band effectively, so the multi-longitudinal mode and mode jumping in other normal fiber ring laser are removed in this one.

将未泵浦掺铒光纤作为饱和吸收体，利用驻波干涉在掺铒光纤中诱发的自写入光纤光栅，由于自写入光纤光栅具有窄带滤波特性及对边模有效的抑制作用，解决了一般光纤环形腔激光的多纵模和易跳模之问题，获得具有极窄线宽，不跳模时间大于3小时单频激光输出。

The mode simulated the propagation of guided wave in a pipe by applying the longitudinal ultrasonic to the pipe end.

利用有限元方法建立管道导波3-D模型，通过在管道中激励纵向超声波，模拟导波在管道中的传播形态。
