| Abstract: | The scale-free network theory is introduced to analyze the structure of scientific knowledge.By investigating the structure of scientific knowledge,we point out that scientific knowledge has a scale-free network topology characteristics.Analysis the specific micro-mechanism in scientific knowledge network,find the correct methods based on B-Amodel.Analysis the robustness and frangibility of scientific knowledge network,clarify the mechanism in topology of scientific knowledge network during scientific revolutions.Finally,considering the theory of dissipative structure,define structure entropy of scientific knowledge network.Analysis the direction and progress of the evolution of science based on study about topology of scientific knowledge network. |
