Abstract: The terminology theory has formed a relatively complete science system,while the position and internal partition of terminology in the entire disciplinary system have not been cleared. Modern scientific knowledge system can provides methodological reference,in which Mr.QIAN Xueshen’s principle for dividing the framework of modern scientific theory is significant to the position and internal partition of terminology. Terminology theory can be divided into three gradual levels: basic theory,technologic science and engineering,which embody the disciplinary structure from macroscopic view to specific view. At the same time the principle of crossover step by step should be followed in the study of inter-discipline,and theories of other disciplines should be introduced into the research of Terminology.

Key words: systematic of science and technology, discipline, terminology
