In an ultrahigh vacuum chamber with a base pressure of 1 x 10-10 torr, we have used Low Energy Electron Diffraction and Temperature Programmed Auger to study the effect of adsorbates on the surface structure of Nb(111). That is, in O/Nb(111) systems, we observe the structure of the surface with LEED to see if any surface reconstruction occurs after annealing and analyze the structure.

在超高真空(约1 x 10-10 torr)的环境下，我们利用了低能量电子绕射(Low Energy Electron Diffraction， LEED)、可程式控温欧杰能谱(Temperature Programmed Auger， TPA)，来研究氧覆盖层对於铌基板的影响，亦即PO/Nb(111)表面系统中，再利用LEED观察是否有任何表面重构的现象发生并详细分析此结构。

This paper discusses the information system box structural analysis and designs in three kinds of basic structure : black box, state machine and white box, and give each structure of definition, structure, counteract the language of BDL to describe.

1引言在结构化程序设计中我们通常采用顺序结构、选择结构和循环结构，它们可以互相嵌套。但在大型系统设计时，特别是在分析设计阶段，往往需要更高层次的抽象结构。

E. OCB mode LCD elements . Then,we added bi-functional powder and LC E7 in the bulk copolymer of Poly Acrylic Acid and EOPO,then poured the LC solution,and exposed it with 5V voltages under ultraviolet radiation. Finally,we observed the changing phenomena of the planar display of OCB cell with additional external voltage under polarized microscopy . It can be observe obviously the polymer wall in OCB cell when NO.4 LC solution having concentration of 3％ wt . At the same time,the polymer which didn't sheltered by mask will polymerize,then,lead LC into high inclined angle alignment. And it formed discontinuous structure along mask affected LC which surrounded the wall. The results measured by photoelectric instruments showed the discontinuous structure not only keeps the inner LC structure at twist mode,but also promotes the originated respond-velocity of OCB.

然后利用聚丙烯酸与EOPO之团聚共聚合物，添加双官能基粉体及液晶E7，制备成液晶溶液再注入液晶盒里，放置光罩并给予固定外加5V电压在UV下进行曝光，然后在偏光显微镜下外加电压观察液晶盒的平面显示变化现象，发现四号高分子的液晶溶液在3%时，可以明显观察未被光罩遮蔽的高分子将会聚合形成高分子格子结构，并造成液晶成高倾角排列，顺著光罩形成不连续的结构藉以影响墙周围的液晶，从光电量测结果显示，利用此种不连续结构不仅可将内部液晶结构维持在twist的状态，也成功提升OCB原有的响应速度。

This article introduces the analysis and design of UAM from two aspects: structure of the system and data model, which relate to net structure, function structure, technique framework, database design, etc.

从系统结构和数据模型2个方面阐述了UAM系统的分析设计，具体涉及到网络结构、功能结构、技术架构以及数据库设计等多个内容。

Microscopic characteristics of cladded crystal fiber are analyzed by X-ray diffraction, Laue X-ray diffraction and scanning electron microscopy, it is found that magnesium-ion indiffusion does not affect the single crystal structure and the domain structure of the magnesium diffused crystal fiber. It is found for the first time that MgO-rich layer in the magnesium diffused LiNbO〓 surface layer exhibits the crystal structure of an unknown compound from the Li-Mg-Nb-O ternary system and MgNb〓O〓. It is proposed for the first time that this unknown compound and MgNb〓O〓 in MgO-rich layer are the real sources of magnesium-ion indiffusion LiNbO〓. Their appearance indicate that MgNb〓O〓 is in the surface layer of MgO-rich layer, the unknown compound is in the subsurface layer and beneath where the MgNb〓O〓 is located, and these compounds have obviously preferred orientation.

通过镁离子内扩散法，首次在国内实现了具有阶跃和抛物折射率分布的c轴LiNbO〓单晶光纤和a轴Nd：MgO：LiNbO〓单晶光纤的芯—包层波导结构，为我国在该项目的研究填补了空白；建立了晶纤损耗的测量系统，提出了利用单模石英光纤作为晶纤入射光耦合器的思想；通过对晶纤损耗的测量，得到了包层晶纤比未包层晶纤损耗降低约14倍的好结果，并实现了低次模传输：对经镁离子内扩散实现包层后的晶纤的微观特性，利用X射线衍射，劳厄照相和扫描电镜表征发现，晶纤并不因镁离子的内扩散而影响其单晶结构和镁的扩散层畴的变化。
