Disciplinary structure of natural science history and great science history

After hundreds of years' evolvement and development, natural science history has entered into an initially mature stage, which can self-understand itself. There are several established and un-established branch disciplines which can be demarcated by seven discipline groups: history of general science, history of science integration, history of science disciplines, history of science social activities, history of special science system and history of special science achievements. Great science history refers to the science history whose research range involves all of the science categories. In the course of researching into great science history, special attention should be paid to the historical survey of the rising science categories on the dimension of analysis and emphasis on the historical review of interrelation between each science category and relative basic research of general great science history on the dimension of integration.
