中文摘要：

产品的概念设计对其最终设计结果具有重要的影响。提出了支持产品概念设计的知识网络模型，通过该模型将显性知识进行组织，以支持产品需求转换为产品功能，进而转换为产品结构的概念设计过程，并根据模型对产品参数间的隐性联系进行挖掘，使其转换为显性知识以支持重用。通过对某工业汽轮机转子通流部分设计过程的知识网络应用过程给出实例论证。

英文摘要：

Product conceptual design affects the final design results seriously. Knowledge network model is proposed to support product conceptual design. Based on this model, explicit knowledge can be organized to support the process of transforming requirements into functions, and then into structures; tacit relationships between product parameters can be found out that tacit knowledge may be transforming into explicit knowledge to reuse.The knowledge network application process of industrial steam turbine rotor flow division section is tanken as an example.
