摘　　要：用VB脚本查询中尺度自动气象站SQL Server 2000中心数据库,在VB 6.0下编程调用绘图软件Surfer 8的Automation功能,对查询得到的数据进行图形分析,通过系统剪贴板将Surfer 8在后台绘制好的图形复制到图片框进行前台显示。将查询信息输入和图形显示功能模块编译成Active X控件,插入网页文件,实现了将任意时段的中尺度自动气象站资料以图形的形式在互联网上为用户服务,克服了目前多数网站只提供固定时段气象资料分析图形的问题。系统采用了模块化和控件的方式进行开发,减轻了开发工作量,方便了系统发布。The system queries the central SQL Server 2000 database of mesoscale automatic weather stations by VB Script. The automation function of Surfer 8 is used to analyze the gathered data in VB 6.0. The generated graphs are copied to the picture frame through the system clipboard. The querying-information input module and graph display module are compiled into Active X and linked into the Web page. The graphic service of any period to the users through the Internet is realized. The problem that most Web sites supply only the graphs of a specific period is resolved. Because the module and Active X technology are applied, the program editing workload is reduced, and the issuance is easier.
