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。

Between the chaos caused by war, the political struggle, the human and the human engage in factional strife, the traditional morality to crush mutually, the majority of people have not been able to accept holonomic system's good education, after with great difficulty reform and open policy, also encounters the organizational reform, comes off sentry duty, the medicine changes, the reform of the housing system and so on and so on, says regarding their this generation of people, the survival, continuously the survival which paces back and forth nearby the low-income level as well as to survive all sorts of endeavors which makes and struggles, is primary coverage which they live, in theirs idea, lives is most important.

战乱、政治斗争、人与人之间相互倾轧、传统的道德观念被粉碎，大部分人未能接受完整系统的良好的教育，好不容易改革开放后，又遭遇体制改革，下岗，医改，房改等等等等，对于他们这代人来讲，生存、一直在贫困线附近徘徊的生存以及为了生存做出的种种努力和挣扎，是他们生活的主要内容，在他们的观念里，活下来才是最重要的。

A high level ab initio method and an ABEEM/MM model had been applied to study the hydronium ion clusters H3O＋(H2O)n (n＝1～6). The low energy geometries had been optimized and the binding energy and the stability had been discussed, revealing the preponderant existence of the local structure of the H3O＋(H2O)3 cluster.

RESULTS The proliferation of fibroblasts was inhibited by K102 in vitro. A dose-dependent antagonistic effect was found between K102 and bFGF. The serum levels of ALT, AST and the liver hydroxyproline level in the treated groups were lower than that in the CCl4 model group. Pathological examination showed a slight fatty degeneration and hydropic degeneration was observed in the group treated with the high dose K102, the low dose K102, and the control group.

But if you want to date your anxious inamorato, where to meet in a coffee house of dim light, then you could need that a peachblow cheek, a glittering and translucent lip, tri-level eye black, incompact crimp and the dressing of erogenous low-laying breast. In generally, what we suppose all can be designed by our subjective activity and put in practice by external means, thereby reaching final goal.So do not casually ask me " What design does fit for me?......"

但如果你今天要见的是你久未谋面的情人，相约在灯光昏暗的咖啡屋，那么你可能就需要一个桃红色的腮红，满是珠光的唇冻，三层蓝蔻睫毛膏，松散的卷发和性感的低胸装，这些都只是笼统的讲，我们想要得到什么都可以靠我们的主观能动性去策划，客观手段去实施，从而达到最终的目的。
