The main works include: In this thesis, we use Finite Difference Time Domain method to study the relationship between diffraction efficiency, angular dispersion and grating constant, to discuss how the grating figure influence the diffraction efficiency, and to research the frequency spectrum characteristic.

主要工作包括：本文分别在垂直入射和自准直入射（光垂直于光栅刻槽面入射）情况下，采用时域有限差分方法，利用商业数值计算软件OptiFDTD对二维闪耀光栅进行了矢量电磁场数值计算，研究了光栅的衍射效率和角色散随光栅常数的变化情况，研究了光栅形状对光栅衍射效率的影响，还讨论了各种光栅的频谱特性。

Because of wide spectrum bandwidth of the mode-locked laser, When the AOD works, the light spot of the 1 st diffraction order will be distorted by significant angular dispersion, thus reduces the spatial resolution of the image.

研究表明：由于飞秒激光在锁模情况下具有较宽的光谱带宽，经过AOD后的一级衍射光斑带有严重的角色散，导致光斑形状发生畸变，影响成像的空间分辨率。

The method of moments in conjunction with the asymptotic waveform evaluation technique is applied to predict the mono-static RCS of an arbitrarily shaped two-dimensional cylinder in both frequency and angular domains.

本文采用矩量法并结合渐近波形估计技术在频域和角度上预测了任意形状二维柱体的单站RCS。

This boy has an ok shoulder and good rear angulation with correct length and shape of croup.

At this temperature the mineral anhydrite, which was abundant in the water, dissolved into gypsum, a soft mineral that can take the form of the crystals in the Naica cave

在此温度下的无水石膏矿是十分充足的存于水中的，并且分解成Naica山脉里易于形成各种形状水晶的软矿石。

Malaysia: The groom's gifts to the bride are delivered to her home by costumed children in a noisy procession, carrying lavish trays of food and currency folded into animal or flower shapes

马来西亚：新郎赠送给新娘的礼物由盛装打扮的孩子们组成的热闹队伍送过去，孩子们捧着许多盛有食物和用钱折叠成的动物和花卉形状的托盘。

This is more of a breast anomaly than a shape.

这是更多的乳房异常比一个形状。

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.
