查询词典 gratings

During the manufacturing process of OFBG-FRP rod, optical fiber Bragg gratings were pultruded in series along with host materials, i.

在OFBG-GFRP的拉挤过程中，多个串连的光栅随同母材，即GFRP筋一同拉挤成型。

Then some improvements which bestow the cavity with certain characteristics are achieved on the basis of the original laser. There are more adjustment factors, such as the detuning of gratings and the length of the cavity. The resonance cavity can make use of each other better, and the synchronization of the dual-wavelength laser can be improved.

然后我们在原有激光器的基础上做了一些改进，改进后的腔具有的优点有：腔的调整因素有所增加，比如镜的失调，腔的长度；同时可以改变两谐振腔的相互利用情况，以便更有利于双频激光的同步运行。

The flexible nature of ASOC technology means it can also be utilized to provide application specific, high functionality, high value devices including Arrayed Waveguide Gratings and Variable Optical Attenuators.

ASOC技术的灵活性意味着该项技术同样可以应用于提供偏向于应用的、功能广泛的高价值元器件包括阵列波导光栅以及可调式光衰减器。

In the case of short light pulses irradiance, photovoltaic effect has no effect on the writing and erasing photorefractive gratings in the LiNbO3 crystal.

因此，在短脉冲光入射光折变晶体材料情况下，考虑光生伏打效应与不考虑光伏效应，对短脉冲光在光折变LiNbO3晶体中写入和擦除光栅基本没有影响。

Based on Valley's quasi-cw approximation, the writing and erasing of gratings in materials exhibiting bulk photovoltaic effect on illumination with short light pulses is investigated.

利用G.C.Valley的准连续光近似模型，研究了短脉冲激光在光伏光折变材料LiNbO3晶体中写入和擦除光折变光栅的过程，给出了空间电荷场随时间变化的表达式。

Vincent de Paul has divinely traced the features of the Sister of Charity in these admirable words, in which he mingles as much freedom as servitude:"They shall have for their convent only the house of the sick; for cell only a hired room; for chapel only their parish church; for cloister only the streets of the town and the wards of the hospitals; for enclosure only obedience; for gratings only the fear of God; for veil only modesty."

味增爵在下面这几句名言里已经神妙地把一些作慈善事业的姆姆的面目刻画出来了，并且把她们的自由和劳役融成了一片：&她们的修道院只是病院，静修室只是一间租来的屋子，圣殿只是她们那教区的礼拜堂，回廊只是城里的街道和医院里的病房，围墙只是服从，铁栅栏只是对上帝的畏惧，面幕只是和颜悦色。&

In the modeling of recording optics, the main contents of this thesis are: deriving the fourth-order analytical model for the recording optics with auxiliary spherical mirrors and auxiliary uniform-line-spacing plane gratings, providing the numerical ray-tracing models based on Fermat's principle and local search, and analyzing the expansion errors of analytical models.

本文在记录光路建模方面的主要工作是：针对使用辅助球面镜与辅助等间距平面光栅的两种记录光路，推导了四阶解析模型，给出了基于费马原理与局部搜索的光线追迹数值模型，并分析了解析模型的展开误差。
