摘　　要：介绍了分布式环境下产品数据的合成机制,分析了数据合成中的两个重点环节——数据定义和数据提取。指出了当前采用的数据定义和数据提取方法的不足,并在此基础上提出基于数据本身逻辑关系的数据定义和基于比较推理的数据提取技术。以863/CIMS项目工艺信息管理系统为应用背景,对相关技术进行了应用验证。The product data integration mechanism based on distributed environment is introduced. Two important links -- data definition and data extraction in data integration are analyzed. The disadvantages of data integration and data extraction methods being used now are pointed out, and new methods of data defi- nition based on logic relation of data in itself and data extraction based on comparison reasoning are proposed. With the process information management system of 863/ CIMS project being as the application background, the related techniques are verified in practice.
