The third key-press is regarded as letter affirmance key-press on mini key-board, at the same time, identifies sound, the identical method is: identifying the three sounds by lengthways three lists, identifying the three rhymes by transverse three rows, the intersectant is the whole identifying key-press of sound.

小键盘以输入第三键作为字符确认键，同时识别声韵，识别方法是：以纵向三列键识别三声；横向三排键识别三韵，纵横交合键位就是该音节的声韵全识别键。

The BCH coded authentication data is modulated by chaotic sequence and then embedded into the DCT domain of the image by using the owner's private key.The embedding process is controlled by Just Noticeable Difference of the DCT block.Users can extract the authentication data with the public key,while they can't get the private key to destroy or delete the watermark through the public key.

提出一种基于非对称水印的图像认证改进算法，算法中将经过BCH编码和混沌序列调制的认证信息作为水印，利用所有者私钥嵌入图像DCT域，嵌入过程根据DCT块的可视噪声阈值控制，用户可以利用公钥从水印图像中提取认证信息，但无法从公钥中获取任何私钥信息，从而无法破坏或删除水印。

METHODS: A computer-based online search of PubMed database was undertaken to identify related articles about the microcapsulated cell or encystation material for treating diabetes mellitus published from 1980 to 2009 by using the key words of "microcapsulation, islet, transplantation" in English. Meanwhile, we search CNKI for relevant articles published between 1999 and 2009 with the same key words in Chinese.

检索PUBMED数据库中1980/2009有关人工细胞微囊技术进展在糖尿病中应用的文献，检索词"microcapsule， islet， transplantation"，并限定文献语言种类为English；同时检索中国期刊全文数据库1999/2009有关人工细胞微囊技术进展在糖尿病中应用的文献，检索词为"微囊，胰岛，移植"。

You can put all your passwords in one database, which is locked with one master key or a key file.

Secondly, the key techniques of the embedded database system in this experiment, such as memorizer management, query management and data synchronization replication, are further researched. The massive materials consult, the analysis and the research had been carried on and the key effects on the performance of the system had been discovered:(1) numbers of I/O of external storage;(2) numbers of repetition of parse SQL.

其次在实验的过程中，对嵌入式数据库系统中的存储管理、查询管理和数据同步复制等几项关键技术进行了深入研究，经过大量的资料查阅、分析和研究，找出了影响系统性能的关键所在：(1)外存I/O的次数；(2)重复解析SQL语句的次数。

Database encryption and user-dependent restorable key management scheme insure the security of key storing, backuping and restoring.

给出了数据库加密技术和依赖用户的可恢复密钥管理机制的设计，实现了用户密钥的安全存储、备份与恢复。

In chapter 5, I describe the tools, the flat roof and their key technology. And by illustration I emphasize the database design and its key technology.

RETRIEVE STRATECY: A computer-based search in High Wire Press was undertaken to identify the articles publish in English between January 1959 and June 2007, with the key words of "boxing, injuries". Meanwhile China Journal Full-texts Database was retrieved for the related articles from January 1995 to June 2007 by using the identical key words in Chinese.

检索策略：用计算机检索High Wire Press 1969-01/2007-06年期间的相关文章，检索关键词为&Boxing， injuries&，同时在中国期刊全文数据库中检索，1995-01/2007-06期间的相关文章，检索词为&拳击，损伤&。

The map symbolization is the first key in this model. The spatial data can be compiled through map symbols. For publishing paper map, some approaches, for examples, area feature symbolization, feature covering, making mask and so on, are accomplished on the process. It is the second key that spatial attribute database management is applied in digital mapping.

本文指出解决空间数据的地图表达是实现一体化生产模式的第一个关键，其中地图数据符号化技术贯彻全部过程，实现了基于地图符号的空间数据生产，并在地图出版阶段，通过面状符号配置、要素压盖、蒙片等地图出版处理技术，实现地图出版；本文把属性管理技术应用在地图制图中，实现了属性数据库支持下的地图编辑。
