In this dissertation, we optimized the thinkness of each layer of TFEL devices using the layered optimization method to obtain ZnS: Ce〓 TFEL devices. Accoding to the energy level structure of Ce〓, two criteria for distinguishing the EL of Ce〓 were found out, from which it was conduded that the TFEL of ZnS: Ce〓 comes from 5d→4f transition of Ce〓. The measurement of brightness waveform showed that the TFEL of ZnS: Ce〓 was the luminescence from independent centers. and there were the field induced-delocalization in this process anf it〓s the cause of low TFEL efficiency of ZnS: Ce〓. In this dissertation, different influence factors on TFEL of ZnS: Ce〓 were sdudied. The influence of different host lattice is different: The blue/green ratio of ZnS: Ce〓 in hexagonal system of ZnS is larger than that in cubic system of ZnS, and the TFEL peaks in hexagonal system of ZnS moves toward longer wavelength compared with that in cubic system of ZnS. The adding buffer layer was used in this stage. The solubility of Ce〓 in ZnS was small and it was another limit to TFEL brightness of ZnS: Ce〓 device. The solubility of Ce〓 increased ten times when using Li ions as flux, so that the TFEL brightness of ZnS: Ce〓 was enhanced. It was found that the appearing of ZnO in active layer improves the TFEL of ZnS: Ce〓: the brightness and the wave range of ZnS: Ce〓TFEL were enhanced.

本文采用TFEL的分层优化方案，优化组合了各膜层厚度，选择最佳制备条件，得到了ZnS：Ce〓的TFEL；根据Ce〓的能级结构，找到了判别Ce〓的EL的两个简单依据，并据此断定ZnS：Ce〓的TFEL的两个发射峰分别属于Ce〓的〓和〓跃迁；亮度波形测量表明ZnS：Ce〓的TFEL属于分立中心发光，分析认为在此过程中存在着较严重的场致离化，这也是ZnS：Ce〓的TFEL效率较低的一个原因；本文考查了影响ZnS：Ce〓的TFEL的各种因素，发现：基质的晶体结构对ZnS：Ce〓的TFEL有所影响，在六角相ZnS中Ce〓的TFEL优于立方相ZnS中Ce〓的TFEL：发射峰的蓝-绿比相对较大，且光谱向短波方向移动，在此项研究中本文采用了在发光层前增镀过渡层的办法，过渡层为六角晶相的ZnO；限制ZnS：Ce〓的TFEL器件亮度的一个原因是Ce〓在ZnS中的溶解度低，本文用Li离子作助溶剂增大了Ce〓的溶解度，增大幅度为一个量级，并且ZnS：Ce〓的TFEL亮度明显提高；从ZnS：Ce〓的TFEL光谱来看ZnS：Ce〓的TFEL波长覆盖范围较小，亮度也不高，达不到做为白色TFEL材料的要求，需要寻找新的白色TFEL材料；在研究ZnS：Ce〓的TFEL中还发现：发光层中ZnO的出现有利于ZnS：Ce〓的TFEL：发射峰变宽、亮度增大。

However, the image-retrieving environment is so complicated, such like from a nature object to a variety of objects, from a light environment to a dark environment, or from a nature light to a daylight in office, the properties of objects, and the varieties of light sources and light intensities. These complex external image-retrieving environments let users can not get an accordant image quality. Such under a tungsten lamp, the image appears yellowish and reddish; under daylight in office, the image becomes greenish and bluish.

CCD Camera面对的是复杂的取像环境，从自然景物到各式各样的景物，从光亮环境到灰暗环境，或从自然光到办公室日光灯、景物的特性、光源的种类及光线的强弱，这些外在复杂的取像条件及变因往往让使用者无法得到相当一致的影像品质，如在钨丝灯下拍摄的影像，将产生偏黄、偏红效果的影像；在办公室的日光灯下将产生偏绿、偏蓝效果的影像。

Purified GO had a molecular weight between 145, 000 and 162, 300, as determined by Sephadex G-200 filtration and SDS-PAGE of the enzyme as cross-linked with glutaraldehyde. This result showed that the holoenzyme was a tetramer, and no change occurred in molecular weight of the enzyme during the s〓orage. The active form of GO from brassica leaves showed a constant molecular weight during purification, so did that from O. sativa leaves during greening of etiolated seedlings, maybe acting as a stable tetramer.

On the basis of the cultural axis, in the city's brain----the Citizen Center, there forms the guide idea for the city's development and construction, while the Citizen Plaza is revealed as that the guide idea sublimes to be a great power which could promote the society after melting with the suggestions and advices of the populace. This power grows with the green river and becomes stronger and stronger, passing by the south plaza and south main axis in the center plaza, finally reaches the climax area----the conference and exhibition center, the display district for the society's productive forces.

在文化轴的基础上，城市的大脑－市民中心产生城市发展建设的指导思想，市民广场则表达为这种指导思想在与来自四面八方的群众的意见和建议融汇后，升华成为可以推动社会进步的力量，这股力量随着绿河成长，由弱变强，其间经历了中心广场南广场和南中轴（市民休闲和商业活动复合区），最终到达了高潮点——会展中心，即社会发展力水平和社会财富的展示区。

To do this you need to get the code for the beakers in the lab by riding the little green car on the lake floor around to the window outside the lab and noting the proper proportions of each color liquid.

你要做的第一件事是变大。先要在湖面上乘小绿车来到实验室外的窗户旁注意观察每种颜色液体的合适容积以获取烧杯的代码。

The next development in musical notation were "heighted neumes", in which neumes were carefully placed at different heights in relation to each other. This allowed the neumes to roughly indicate the size of a given interval as well as the direction. This quickly led to one or two lines, each representing a particular note, being place on the music with all the neumes relating back to them. At first these lines had no particular meaning and instead had a letter placed at the beginning indicating which note was represented. However, slowly the lines indicating middle C, and the F a fifth below, became most common. Having at first been merely scratched on the parchment, the lines now were drawn in two different colorded ink: usually red for F, and yellow or green for C.

音乐记谱法的再一次新发展是heighted neumes，这种记谱法标识出音符之间的音高关系，这样就使得纽姆谱可以粗略并直接地标记出指定音程的增减，这样的标识方法导致了谱上一线或者二线的出现，每条线代表一个特定的音符，这个音符与纽姆谱中所有的音符的音程关系都能被标识出来，最初这些线并没有什么特殊的含义，反而会有一个字母被放在开始的位置表明代表哪个音符，渐渐的，线代表中央C或者比C低五度的F 变得最常用，这些一开始只不过在羊皮纸上刮出的线，开始用两种不同的颜色书写，红色代表F，黄线或者绿线代表C，以上的这些便是我们所知道的音乐记谱法发展的开端。

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.
