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。

The fundamental of longitudinal guided wave NDT magnetostrictive transducer is explained.

阐述了纵向导波磁致伸缩传感器应用于钢管无损检测中的基本原理。

The responses of roll motion were obtained for the ship in irregular longitudinal waves of 10m and 12m significant wave heights with respect to the initial roll angle of 3°and the bias heel angle of 5°which was assumed to be caused by the permanent wind pressure.

华建波对随浪和尾斜浪航行的耐波性进行了深入研究[1]，采用计算机仿真研究了在纵浪中滚装船的参数激励运动，此外，他还提出了在规则和不规则

The split between the two groups can hardly be papered over.
