Specific introduction to the relevant classification of archive boxes:

1. Time classification method, according to the composition time of science and technology archives or the time characteristics reflected by the content of the archives. It is convenient to analyze and discuss the scene, hydrology and other disciplines in the relevant time from the perspective of historical contact. To

2. The regional classification is based on the regional characteristics reflected in the content of the science and technology files. It's like sight, hydrology, geology, etc. In terms of content and composition, it has outstanding regional characteristics.

3. The professional classification method is based on the professionalism reflected in the scientific and technological archives, and the other methods are stopped. It is mostly suitable for scientific and technological archives whose tools and content are standardized, generalized or highly interchangeable, and suitable for enterprises and institutions that use scientific and technological archives from an amateur perspective. The feature is that relevant scientific and technological archives are combined according to the amateur nature, which is convenient for searching and applying scientific and technological archives from an amateur perspective, and is convenient for constructing the same type of production, promotion and growth of standardized things. Such as civil engineering, layout, HVAC, etc.

4. Project classification method, applicable to infrastructure files, engineering design files and construction files. Take the engineering project as the classification unit. Its characteristic is that all the science and technology archive boxes of the same project are combined together, without breaking the boundary of the project, reflecting the whole picture of a project, and it is convenient to find and apply irrelevant and science and technology files according to the project.

5. The model classification method is applicable to the classification of product archives and equipment archives. Take each Jin product or each type of equipment as the classification unit, and separate the other methods. The feature is: the product or equipment files of the same model are combined together, and the complete set is adhered to. It reflects the overall picture of a product or equipment and the layout and subsidiary relationships between external groups and components, which is convenient for complete application.

6. Subject classification method is applicable to the classification of scientific research files. It is within the scope of the entire scientific research file box, with each independent research topic as the classification unit, and the method of separate department files. Its characteristic is to facilitate the completion of a complete set of convergent management of the archives of a research topic, to systematically reflect the natural process of the research topic, and to facilitate the search and application by topic.
