After quantifying knowledge difference,knowledge level, knowledge uprush,knowledge oblivion,the characteristics of knowledge growth in the course of team knowledge communication were discussed.

It advances a model of knowledge conflict process based on knowledge heterogeneity.

Based on the definition of the knowledge conflict and its types,the group effectiveness and its measurement,the relationship model between the knowledge conflict and the group effectiveness is setup,certain hypotheses are brought forward and investigation questionnaires for the case verification are obtained by visiting more than 120 group-members with group-work experiences in 10 companies.

Aiming at team’s knowledge conflict,this paper introduces"temporal framing effect",an important contextual factor,to establish a new type of conflict management mechanism.

And then we study carefully the reader s knowledge conflicts carefully and analyze the reason,type and character of knowledge conflicts.

This paper analyses the Knowledge taxonomy, and then discusses the root ,styles, and process of knowledge conflicts, which in order to provide a new theory framework to analyse the know.
