Abstract: Take the discovery of unsymmetry of parity conservation as a case, the paper constructed the knowledge structure and knowledge chain of the scientific discovery by co-citation analysis, analyzing its knowledge source, logic relationship among knowledge and the knowledge renewing process .The results have shown that 1)all knowledge caused the discovery had come from one field but belonging to different topics; 2) logic contradiction existed in the relationship among knowledge and a lot of structure holes existed in knowledge network; 3) the knowledge renewing process could be divided into some steps and levels. From the case study, co-citation analysis is proved as an effectively approach to construct knowledge structure and research the pattern of scientific discovery. Future research also has been presented.
