微波滤波器综合的出发点在于滤波函数的选择,滤波函数的性质决定了滤波器的响应。文中提出了一种广
义的巴特沃思滤波函数,在保留其群时延上优势的同时,通过引入有限位置的传输零点,大大的改善巴特沃思函数的带外
特性,使得其可以适应现代通信技术对微波滤波器的要求,在微波滤波器的实际设计中具有很好的应用价值。-Microwave filters and integrated starting point is the choice of filter function, filtering function, the nature of the filter response. This paper presents a generalized Butterworth filter function, while retaining the advantages of their group delay at the same time, through the introduction of limited number of locations of transmission zeros, greatly improve the function of the band Butterworth characteristics, making it to adapt to modern communications microwave filter technology requirements, the actual design of microwave filters has a very good value.

第二十一世纪是知识的时代
21世纪是知识经济的时代，组织和利用知识信息的有力武器――数据库将继续得到广泛应用。数据库(Database，即DB)是存储在一起的相关数据的集合，是存储数据的“仓库”。其名词源于20世纪50年代，美国为战争的需要，把各种情报案中在一起，存入计算机。60年代数据库帮助设计了阿波罗登月火箭，推动了数据库技术的产生。70年代，数据库蓬勃发展，网状系统和层次系统占领了市场，并且关系数据库理论也日趋完善。80年代起，关系数据库产品已相当成熟，后来有了分布式数据库系统(Distributed Database Systems)、数据库机(Datsbase Machines)、知识库(Knowledge Base)系统相知识机。现在，数据库技术已成为计算机领域最重要的技术之一，它是软件学科中一个独立分支(即研究数据库的结构、存储、设计和使用的一门软件学科)。-The 21st century is the era of knowledge-based economy, organization and use of knowledge and information of a powerful weapon- the database will continue to be widely applied. Database (Database, or DB) is stored together a collection of related data is stored data "warehouse." The term originated from the 20th century, 50 s, the United States for the war needs, the case of the various information together into a computer. 60 s database to help design the Apollo moon rocket to promote the generation of database technology. 70 years, vigorous development of the database, network systems, and levels of the system o

基于C++Builder 6的医药类单据打印系统，主要是Access + FastReport + VCLSkin的一些综合应用，重点功能是FastReport中实现人民币中文大写、空行补齐，页面小计(SubTotal)等……
本打印程序开发过程中使用了FastRepot和VCLSkin组件，源程序在编译时需要在工程(Project)的选项(Options)中更改一下Include和Lib的路径，指向你的FastReport的安装目录。否则会提示找不到头文件等编译错误。
-Based on C++ Builder 6 categories of documents of the printing system of Chinese medicine, primarily Access+ FastReport+ VCLSkin the number of integrated applications, with a focus function is to achieve FastReport Chinese Renminbi capital, filled blank lines, page Subtotal (SubTotal) and so on ... ... this printing process used in the development process FastRepot and VCLSkin components, source code at compile time the need for the project (Project) options (Options) to change the look of Include and Lib path FastReport point to your installation directory. Otherwise will be prompted to find header files, such as compiler error.
