摘　　要：变动产品模型是从现有的产品数据模型中归纳出来的一类新的产品数据理论模型，具有许多新的性能特点，是新一代ＣＡＤ／ＣＡＭ系统中产品数据模型的研究核心。本文在总结一般产品数据模型的特点之后，提出变动产品模型的形式化定义，分析了它的特点和性质。Variational model is a new kind of theoretical product model induced from those models currently provided. It has some new characterics and is the key research subject of product data model for new generation of CAD/CAM system. After introducing some new ideas about general product data model, this paper provides the formal definition of the variational product model, including its functions, characterics and main applications. Finally, the key problems left are listed for future research.
