光纤

The using of the fiber-optic detector can decrease the loss of light energy to reduce the unorder light's effect and can make the testing system flexible.

集光系统主要是指用于光能收集和传输的光纤探头，光纤探头的使用一方面使光能损失减少，不受环境杂散光影响，另一方面灵活性大，便于测量样品各个部位的颜色，实现微区测量。

Single-longitudinal-mode laser output can be realized by employing a Fabry-Perot filter and a saturable-absorber-based autotracking filter composed of an unpumped EDF and an optical reflector.

而本S频段的单模光纤回路型雷射是利用一个S频段的EDFA模组、一个光纤式法布里－珀罗（Fabry-Perot）可调滤波器、一段尚未泵激且较短的 EDF及一个反射镜所组成。

By cascading a delay interferometer as a comb filter with a tunable bandpass filter,and employing a saturable absorber formed by a unpumped polarization-maintaining EDF to select the single-longitudinal-mode of the laser, a stable wavelength-tunabledual-wavelength single-longitudinal-mode fiber laser is demonstrated.

4将梳状滤波的延迟干涉仪与可调带通滤波器进行级联，用未泵浦的保偏掺铒光纤饱和吸收体进行单纵模滤波，获得了波长可调的双波长单纵模掺铒光纤环形激光器。

Only an arbitrary single pulse among pulse train with temporal separation of about 1 ps was trapped by soliton pulse,the trapped pulse was blue-shifted and the optical spectra of trapped pulse was distinctly separated from those of the untrapped signal pulses.The trapped pulse can be easily picked off using a wavelength filter such as a fiber Bragg grating.

通过数值求解光子晶体光纤中脉冲传播满足的耦合非线性薛定谔方程，发现用孤子脉冲可俘获信号脉冲串中的任何一个脉冲，被俘获的信号脉冲的中心波长明显蓝移，在频域上和其他信号脉冲分离开来，于是让信号脉冲串在输出端通过布喇格光纤光栅，被俘获的信号脉冲将被过滤掉。

There are two defferent design of hardware: optical fiber temperature sensor is used for middle-voltage Metal-clad switchgear, which data is transferred by optical fiber; another one is 1-Wire Digital Thermometer, it is used for lower-voltage Metal-clad switchgear, and the data is transferred by unwired.

硬件方面设计了两种不同的温度传感系统：中压开关柜过热故障监测采用光纤式温度传感器，同时采用光纤传输数据；低压开关柜采用单总线数字式温度传感器，数据采用无线传输。

The Sagnac interference method and a 1.31μm light source, generally used in fiber-optics current sensor, are used to measure the Verdet values. The measured results are useful in the research of FOCS.

实验数据采用目前研制光纤电流传感器最常用的Sagnac干涉方法，并在最常用的1.31μm波长光源下得到，因此对进一步研究扭转光纤环电流传感器具有实用价值。

According to the analysis of relations between optical power,center wavelength,sensing fiber Verdet constant,and Fiber Optic Current Transformerscale factor,it was demonstrated that the center wavelength excursion generated by power attenuation of SLD was the prime reason of FOCT scale factor error.

通过分析光源功率、中心波长、传感光纤Verdet常量，以及闭环光纤电流互感器变比之间的关系，结合测试数据，证明了中心波长漂移是光源功率衰减引起闭环互感器变比变化的主要原因。

For the first time, we observe the polarization effect in two-core fiber interferometers, for which we give our analyses and explanations in the thesis. This effect can be used to improve the S/N ratio and the stability of the system. Meanwhile, we did experiments to measure strain within a deformed cantilever, and the results are in agreement with our theory.

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
