中文摘要：

本文利用图论对技术创新网络进行描述，分析了技术创新网络中知识的组成，以产品为顶点，给定知识的维度特征；在提出知识能量概念的基础上，分别由给定知识的动能与势能来描述知识在知识时空中的明晰性和模糊性，在此基础上，利用现代场理论构造模型研究既定知识明晰性和模糊性之间的互动变化。以此为工具进一步分析了技术创新过程中的创新阶段与扩散阶段的知识测度特征之间的相互关系，验证了本文提出的知识测度模型。

英文摘要：

This paper describes the techno - innovation network by adopting graph theory and analyzes the component attributes of knowledge within the techno- innovation network -product attributes and organizational attributes, dimensional characters of the given knowledge in the knowledge space that takes the products as its vertices. Then based on a presentation of the concept ＂knowledge energy＂ it describes the distinctness and indistinctness of knowledge in the time - space of knowledge via kinetic energy and potential energy of the given knowledge, on which basis it researches into the interactions between the distinctness and indistinctness of the given knowledge by the means of model analysis which is realized by applying graph theory. Further, it analyzes the interrelationship of the two measures in the techno - innovation process, which are the innovation phase and diffusion phase, and proves the knowledge - estimating model that put forward in the paper.
