滤波法
A、名称:限幅滤波法(又称程序判断滤波法)
B、方法:
根据经验判断,确定两次采样允许的最大偏差值(设为A),
每次检测到新值时判断:
如果本次值与上次值之差<=A,则本次值有效,
如果本次值与上次值之差>A,则本次值无效,放弃本次值,用上次值代替本次值。
C、优点:
能有效克服因偶然因素引起的脉冲干扰。
D、缺点:
无法抑制那种周期性的干扰。
平滑度差。(A. Name: Limited filter method (also known as program judgement filter method)
B. Method:
Based on experience, the maximum allowable deviation (set to A) of two sampling times is determined.
Judge each time a new value is detected:
If the difference between the current value and the previous value is <=A, the current value is valid.
If the difference between the current value and the previous value is greater than A, then the current value is invalid, abandon the current value and replace the current value with the last value.
C. Advantages:
It can effectively overcome the impulse interference caused by accidental factors.
D. Disadvantages:
That periodic interference cannot be suppressed.
The smoothness is poor.)

关于 ZFC 框架的自述文件
2003.6.18
======================================================================
如何在PowerBuilder 开发环境中运行ZFC 框架。
1、文件
app.pbl 常用应用库;
controls.pbl zfc 控件库;
main.pbl 主要对象库;
demo.pbl 演示程序库;
2、目录
DB 演示数据库;
PSR 演示PB报表;
3、基于 ZFC 框架编写程序需要哪些文件和表:
引用main.pbl、controls.pbl、app.pbl 三个库
演示数据库中的Employee,EmployeeToFunction,Function,Profile 四个表;
演示数据库中的usp_DateGet,usp_EmployeeGet,usp_FunctionGet,usp_ProfileGet,usp_ProfileSet 五个存储过程;
如果您使用其他数据库,请移植表和存储过程。
4、PowerBuilder 9.0,Adaptive Server Anywhere 7 必须;(ZFC framework on the readme file 2003.6.18 ========================================= ============================= How to run the PowerBuilder development environment ZFC framework. 1, document library app.pbl commonly used applications controls.pbl zfc Component Library main.pbl the main target of the Treasury demo.pbl presentation library 2, Demo DB database directory PSR demo PB statements 3, based on the framework of the preparation procedures ZFC What are the documents and forms: invoked main.pbl, controls.pbl, app.pbl three library demo database Employee, EmployeeToFunction, Function, Profile four tables demo database usp_DateGet, usp_EmployeeGet, usp_FunctionGet, usp_ProfileGet, usp_ProfileSet five storage process If you use other databases, please transplantation tables and stored procedures. 4, PowerBuilder 9.0, Adaptive Server Anywhere 7 must )

bookmanage
图书管理系统,关键字:Access数据库,VB可视化编程,ADO控件。随着人类社会的发展,人类对知识的需求也不断地增长。在这种形势下,书籍就渐渐地成为人们获取并增长知识的主要途径,而图书馆就自然而然地在人们的生活中占据了一定的位置。
学校作为教书育人的中坚力量,图书馆的作用更是举足轻重。学校图书馆要做到安全顺畅的运转,为广大同学提供良好的服务,就必须有一套完善健全的运行管理机制。联系实际,考虑各层次学校的情况,软件本身要求易学,界面友好,容易掌握,可以较简单方便的管理各种图书信息;硬件的配置要求不能太高,这样可以很好的适应当前的学校图书馆。系统的总体特点应该是方便、简单、实用。
本系统主要实现的功能有:图书的编目,图书资料的查询删除以及修改,用户资料的查询修改以及删除,图书的借阅,图书的归还,添加管理员帐户,修改管理员密码等功能。(aaaaa)
