In aspect of investigation on the binary phase splitting grating, Dammann grating, rectangle grating and also coordinate-phase modulate grating have been studied respectively. Detail analysis shows that the grating phase angle can inflect greater than coordinate to the splitting efficiency and equality rate.

在对二元位相型光学分束光栅的研究方面，在本论文对Dammann光栅、矩形孔径光栅以及坐标位相调制型光栅分别进行了研究，通过对光栅设计参数的变化对分束效率、分束均匀度的影响的分析可以发现光栅位相角对分束效率及分束均匀度的影响要比突变点坐标的影响大得多。

Based on the relationship between the numerical aperture of the objective lens and scale pitch, this study chooses a suitable Plano-convex lenses available on the market, so as to approximate the diameter of the focusing spots to scale pitch. Also, by using the optical path of an optical encoder similar to the nanoscale, the changes in the surface profile of the scale can be measured directly, so as to obtain the two quadrature sinusoidal signals. By counting the zero crossing of these two quadrature sinusoidal signals and calculating the interpolation value of these two quadrature sinusoidal signals, the moving direction and moving displacement value of the scale can be obtained.

研究中再以搭配物镜的数值孔径与尺条间距的关系，选择ㄧ适当的市售平凸透镜，使聚焦光点的直径与尺条的间距相近，并使用相同於奈米级长行程双雷射聚焦读头装置的光路设计，如此将可藉由直接量测尺条的表面轮廓变化，以获得一组正交弦波讯号，继而利用讯号四分割与细分割处理，计算出尺条之移动方向与移动量，研制出一实用性长行程双雷射聚焦读头光学尺。

Two Mode Carrueau Viscosity model showed that polymer and filler had a strong effect on structure orientation, demonstrating that the interaction between polymer and filler in premixing them existed, and the interaction made the polymer and the filler gather in blending the polymer/filler compound with asphalt.

老化使得沥青的软化点及粘度增大，而针入度和延度降低，在红外谱图上主要表现为羰基峰的增大，而亚砜基峰的变化趋势和老化时间及强度相关，老化之初亚砜基峰增大，但随后又减少。

This paper primarily used methods of Historical Citation and Statistic Data Analysis discussed investment environment of Shanghai new economy area, and made case study of Pudong New Area, intending to use related investment and regional development theories such as international production eclectic theory, regional economy gradient transfer theory, growth pole theory, to inspect effect of new economy area investment environment change on metropolitan development.

本文主要透过历史文献分析与统计资料分析方法，探讨上海新经济区的投资环境，并以浦东新区作为个案分析，期望藉由国际生产折衷理论、区域经济梯度转移理论、成长极理论等相关投资与区域发展理论，来观察新经济区投资环境变化对都市发展的作用。归纳研究发现，主要有下列几点：1。

Then dig in and talk about the human planarians in your life, the people who've struck out three times, the gaslighters, the pity mongers, and the Dr. Jekyll/Mr. Hyde transformers.

然后，深入，讨论一下你的生活中的人类真涡虫，那些三击出具的人们，点汽灯的人，同情聚敛者，还有双重性格变化的人们。

These tiny peepers line the upper part of the mantle (seen as orange dots on this specimen) and work together to detect shadows and movements.

这些微小的眼睛位于壳的上部（那些橙色的小点就是它们的眼睛，如图所示），它们一起工作来感知外界微小的变化。

For the understanding of the kinetic variation and distribution of Cl in tobacco area soil of upland yellow-red earth in South Anhui ,soil samples were collected in 4 times of tobacco growth :early winter of 2002,before transplanting in next year, beginning midway, and leaf collecting .

通过对皖南旱地黄红壤烟区进行施Cl处理，施Cl后分别在初冬、次年移栽前、采烤开始、采烤中期、采烤结束后，分五次分别挖土壤剖面取土样；每次剖面层分别取0-20cm、20-40cm、40-60cm、60-80cm的土层土样，同一层同时取4-5点混匀作为一个样品，分析土壤Cl的动态变化。

By adjusting the positions and angles of the two DVD optical pick-up heads, the relative distance of the two laser spots can be equivalent to one quarter of the grating pitch. When the grating moves, the surface profile of the grating can be measure directly, in order to obtain the two quadrature sinusoidal signals. Then by counting the zero crossing of these two quadrature sinusoidal signals and calculating the interpolation value of these two quadrature sinusoidal signals, the moving direction and moving displacement value of the grating can be obtained.

采用两个光学读取头，且两个光学读取头共用同一分光镜与同一聚焦物镜，於搭配光路的设计，可使两个光学读取头之光束打入同一聚焦物镜，藉由调整两个DVD光学读取头的位置与角度，使聚焦物镜聚焦的两相近聚焦光点的距离相等於四分之ㄧ光栅尺间距，当光栅尺移动时，可直接量测光栅尺的表面轮廓变化，以获得一组正交的弦波讯号，继而利用讯号四分割与细分割处理，计算出光栅尺之移动方向与移动量。

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.
