Abstract: Term selection is an important work of examining and approving the scientific and technological terms. Generally, term selecting should be based on the disciplinary framework, and the selected information should be scientific, representative and authoritative. In order to keep the term system balance, systematic and comprehensive, term selection should be divided into groups and levels, and basic terms and new terms should be paid enough attention. Moreover, the term system should be re-arranged and re-organized after new term inclusion, and duplicate terms should be processed.

Key words: examining and approving, scientific and technological terms, term selection
