摘要
在白粉菌属分种性状数据库支持下,以 Foxbase 编程建立分种鉴定数据库管理系统,能够快速、全面地进行各性状比较分析,具有较好的“模糊判别”能力,在一定的概率保证下做出鉴定结论.同时可以列出相近种的性状以供用户参考,可以调用计算机存储的模式标本图形进行核对,系统的灵活性和可靠性都已达到实用化程度.数据库系统的建立和分类鉴定融合在同一系统中,操作的自动化程度较高,有较强的统计分析能力,用户可以十分方便地了解白粉菌属分类性状的有关信息,在计算机帮助下提高分类鉴定的速度和水平.
An expert system on Erysiphe identification has been built in the microcomputer based on the data base which characters Erysiphe.All programs were written in Foxbase.The system runs quickly and gives the multiple judge including Fuzzy diagnosis according to the comparative results.The building of data base and the sample identifying were arranged into a systematic unit,so that users can get detail information about the taxonomic characters and the statistics of Erysiphe from this system to enhance their identify ability.
